When classifying patients by tumor size, however, researchers found that patients with macroadenomas — tumors larger than 10 mm — had higher rates of remission and lower recurrence rates after endoscopic surgery. Patients with microadenomas (tumors smaller than 10 mm) had comparable outcomes with either technique.
In April 2017, the patient arrived at the emergency room with sepsis — a potentially life-threatening complication of an infection — that originated in the gut. Because ketoconazole had failed to lower cortisol levels, the patient started receiving infused etomidate, an inhibitor of the enzyme 11‐beta‐hydroxylase that prevents cortisol synthesis. This treatm […]

Adrenocortical carcinoma is a malignant tumor that develops in the cortex of the adrenal gland. It usually is identified by increased amounts of hormones that are produced by the adrenal glands, like cortisol. This tumor type is very rare in children, representing fewer than two in every 1,000 pediatric tumors.

... I went to my family doctor and asked him for the test it came back showing high cortisol. I also had the 8am and 4pm blood work which came back high indicating Cushings. I sent both those reports to my endo who is in the process of setting up an appointment for me. Finally I have clinical proof. It will be interesting to see how my endo will proceed.
I too have Cushings. Initially I had my 1.8 cm removed and had about three years of feeling better. And I now have a reoccurrence . I started taking Cagaberline but I could not take it. I am currently taking Metyripone....
The UCSF website in an obituary from Kate Vidinsky reads “He took a particular interest in pituitary disorders, those affecting the pea-sized ‘master gland’ at the base of the brain responsible for controlling the body’s hormone levels. He was a pioneer of transsphenoidal surgery – the endonasal approach for removing pituitary tumors – and performed more than 3,300 of these procedures at UCSF Medical Center.”
The New York Times in an obituary published yesterday described him as “a pioneering and virtuosic San Francisco neurosurgeon”.

A 63-year-old man was referred to the Massachusetts General Hospital Neuroendocrine & Pituitary Tumor Clinical Center for management of a pituitary macroadenoma. He experienced increasingly severe retro-orbital headaches in the past year. He reported no double vision, fatigue, orthostatic dizziness, change in beard growth or reduction in libido. An outside head CT scan showed an enlarged pituitary gland.
Imaging and laboratory tests
A pituitary MRI with magnified pituitary slices and gadolinium contrast was ordered. A well-circumscribed “snowman-shaped” sellar mass was identified, measuring 2.6 cm x 2 cm x 1.8 cm (anteroposterior x transverse x craniocaudal) with suprasellar extension (Figure 1). The lesion was heterogeneous on T1-weighted scans after enhancement with IV gadolinium contrast. An area of hypointensity in the superior margin was consistent with a small area of cystic or hemorrhagic degeneration.
Although the mass did not extend laterally into the cavernous sinus, the sellar mass extended upward into the suprasellar cistern through a hole in the dural, the diaphragma sellae, to compress the optic chiasm. The restriction of adenoma growth by the diaphragma sellae results in the snowman shape of the macroadenoma. The optic chiasm and infundibulum (pituitary stalk) could not be identified on coronal or sagittal images (Figure 1). Visual field on confrontation suggested lateral field deficits (bilateral lateral hemianopsia) that were confirmed on formal Goldmann kinetic perimetry visual fields.

A small hypodense area in the adenoma likely represented hemorrhage/cystic degeneration (yellow arrow). The tumor does not surround the carotid siphon, an S-shaped portion of the internal carotid artery (red arrows) within the cavernous sinus located laterally from the sella turcica where the pituitary gland resides.

Initial hormonal evaluation was normal and included morning adrenocorticotropic hormone 18 pg/mL, cortisol 13.64 µg/dL, thyroid-stimulating hormone 2.14 uIU/mL, free thyroxine 1.2 ng/dL and prolactin 12.6 ng/mL. The patient’s morning testosterone level was normal at 324 ng/dL, with follicle-stimulating hormone 2.4 mIU/mL and luteinizing hormone 1.6 mIU/mL. His insulin-like growth factor I level was normal at 124 ng/mL.
Tumor resection
The patient was treated preoperatively with stress-dose hydrocortisone 50 mg. He then underwent transsphenoidal pituitary tumor resection. After the surgeon believed there was an adequate excision of the tumor, the extent of tumor resection was confirmed by an intraoperative MRI (Figure 2 on page 8).
Figure 2. Intraoperative MRI scan. The large macroadenoma is not seen after transsphenoidal surgery. The optic chiasm (yellow arrow) can be seen after removal of the tumor. (A) Coronal image. (B) Sagittal image. Abbreviation: SS = spenoid sinus.
The operation was concluded after the imaging confirmed the complete resection of the pituitary adenoma. The patient’s postoperative course was uneventful. Imaging 4 weeks after the resection confirmed complete resection of the suprasellar mass with residual enhancement of the resection bed and sphenoid sinuses (Figure 3 on page 8). The postoperative MRI revealed a normal optical chiasm and a downward tending of the infundibulum to the residual pituitary gland located inferiorly along the sella turcica (pituitary fossa) of the sphenoid bone. Pathology confirmed a pituitary adenoma. His anterior and posterior pituitary function were normal 6 weeks postoperatively, and his visual field deficit improved.
Intraoperative MRI
Imaging like that used in this case occurs in a specially designed operating room that allows MRI scans during surgery without moving the patient from the surgical table. The MRI is kept in a shielded enclosure during the procedure and then moved along a track into the operating room for imaging. Clinical indications for the use of intraoperative MRI in neurosurgery include resection of pituitary macroadenomas. In the past, these tumors underwent transsphenoidal resection, and the postoperative MRI was performed after 1 or more days after the procedure to check for complete removal. If residual tumor was found, the patients underwent watchful waiting, external radiation or repeat surgery.
The strategic advantage of an intraoperative MRI is that the imaging is performed during the operative procedure, and if there is any residual tumor, surgery can be resumed after the MRI is moved back into the shielded enclosure.

The optic chiasm and infundibulum (pituitary stalk) can be seen after resection of the tumor. The pituitary stalk is deviated to the left of the sella where the residual normal thyroid is locate along the sella turcica. The floor of the sella enhances with gadolinium infusion after surgery due to postoperative inflammation. (A) Coronal image. (B) Sagittal image. Abbreviation: SS = spenoid sinus.
It has been reported that the use of intraoperative MRI does not increase complication rates compared with conventional transsphenoidal surgery. Reports on the improvement of gross tumor resection using intraoperative MRI are variable, perhaps due to the expertise of the surgeon. Several reports suggest the use of intraoperative MRI allowed additional resection of noninvasive macroadenomas in 67% to 83% of the patients with a gross tumor resection. These results suggest that a substantial volume reduction and increased gross tumor resection of pituitary macroadenomas occurs with the use of intraoperative MRI compared with standard surgery. One study demonstrated that the gross tumor resection rates of invasive tumors was also improved with the use of intraoperative MRI compared with usual preoperative imaging and surgery (25% vs. 7%).
The use of intraoperative MRI, especially with transsphenoidal reoperations for invasive and noninvasive pituitary macroadenomas, leads to significantly higher “gross tumor resection” rates. This method prevents additional operations or treatment, such as radiation, because it reduces the number of patients with residual adenoma after surgery. This technology is usually found in specialized tertiary care hospitals but should be considered for reoperation for large pituitary macroadenomas or initial operation for large invasive pituitary macroadenomas.

Ed started as Senior Staff Fellow in the Surgical Neurology Branch at the NIH (1981). After 5 years, Ed would become the Chief of the Surgical Neurology Branch. He would stay on as Branch Chief and lead the neurosurgical effort at the NIH for the next 21 years. During his tenure, he developed clinical, research, and training programs in epilepsy, congenital malformations, syringomyelia, nervous system neoplasia, drug delivery, and vascular malformations. The strength of these programs was his leadership and their multidisciplinary nature, which incorporated physicians and scientists across the basic, translational, and clinical arenas. Research investigation was always targeted at defined clinical problems. Under his direction, these programs shaped understanding of the studied neurological disorders, as well as improving patient care.

Hallmark Health and Tufts Medical Center have established a new neurosurgery program at Melrose-Wakefield Hospital to bring advanced care and services to the community. Fellowship-trained neurosurgeon Mina G. Safain, MD, has been jointly hired by Hallmark Health and Tufts Medical Center to lead the new program. He will provide care at both Melrose-Wakefield Hospital and Tufts Medical Center.
The neurosurgery program is an example of clinical integration of services between Hallmark Health and Tufts Medical Center since Hallmark Health joined Wellforce as a third founding member this past January. At that time, leaders from the organizations discussed finding ways to bring specialized care traditionally performed at academic medical centers into the community hospital setting for the benefit and convenience of patients.
“Offering neurosurgery provides a service for our patients that few community hospitals can offer,” said Steven Sbardella, MD, chief medical officer at Hallmark Health. “Our clinical relationship with Tufts Medical Center enables us to bring more highly specialized care options to our patients.”
“We are extremely excited to work with the physicians at Melrose-Wakefield Hospital and look forward to increasing the services available to care for patients with neurologic diseases,” said Carl Heilman, MD, neurosurgeon-in-chief at Tufts Medical Center. “Dr. Safain is an exceptionally talented and compassionate neurosurgeon and the perfect person to spearhead the launch of this new program.”
Dr. Safain’s clinical interests include all diseases affecting the brain, spine and peripheral nervous system. He has specific interests in minimal access procedures for degenerative, infectious and oncologic spine disorders, as well as minimally invasive treatments for brain tumors, including neuro-endoscopy.
“The opportunity to practice in the community is very important to me,” said Dr. Safain. “I look forward to working with the esteemed staff and providers at Melrose-Wakefield Hospital and Lawrence Memorial Hospital and treating the patients in the surrounding communities.”
“Welcoming such a highly-respected neurosurgeon as Mina Safain to our team is a tremendous benefit for our communities and patients across our system including Lawrence Memorial Hospital in Medford and Melrose-Wakefield Hospital,” said Dr. Sbardella.
Dr. Safain, together with Ran Ku, PA, a neurosurgery physician assistant with more than 12 years of experience, will provide neurosurgery coverage and expertise five days a week.
Dr. Safain received his medical degree from Yale University School of Medicine. He completed his neurosurgery residency at Tufts Medical Center serving as chief resident during his final year. Dr. Safain also completed fellowship training in pituitary and neuro-endoscopic surgery at Brigham and Women’s Hospital.
Dr. Safain has published and presented nationally on a range of topics related to neurosurgical diseases and minimally invasive treatments for brain tumors.
The Cushing/Whitney Medical Library is pleased to announce the completion of a grant funded to catalog 2,600 glass plate negatives from the Cushing Brain Tumor Registry. The grant proposal, “Rethinking Early Neurosurgery: The Harvey Cushing Collection,” was funded through a National Network of Libraries of Medicine-New England Region Knowledge/Data Management Award. From mid-February through April 30th 2017, a team of graduate and undergraduate students carefully inputted information on over 3,000 glass plate negatives into the Cushing Center database, exceeding the estimated amount in the grant. The negatives depict Dr. Harvey Cushing’s patients, including histology.
Harvey Cushing, the pioneer and father of neurosurgery, was born on April 8, 1869 in Cleveland, Ohio. He graduated from Yale University in 1891, studied medicine at Harvard Medical School and received his medical degree in 1895. In 1896, he moved to Johns Hopkins Hospital where he trained to become a surgeon under the watchful eye of William S. Halstead, the father of American surgery. By 1899 Cushing became interested in surgery of the nervous system and began his career in neurosurgery. During his tenure at Johns Hopkins, there were countless discoveries in the field of neuroscience.
In 1913, Cushing relocated to Harvard as the surgeon-in-chief at the new Peter Bent Brigham Hospital. Cushing continued to operate on several hundred patients a year with remarkable results. In addition he was relentless in his recording of patient histories and continued his careful attention to the details and documentation of each surgery.
In 1932 Harvey Cushing retired and in 1933 he agreed to join the staff at Yale University, his alma mater, as the Sterling Professor of Medicine in Neurology. Cushing died in 1939.
The negatives are undergoing rehousing and digitization, and will be made available for research through the Cushing Center database, which brings multiple parts of Harvey Cushing’s work together in one place. The database, still in development, will allow researchers to explore Cushing’s medical work and patients. Please contact Terry Dagradi, Cushing Center Coordinator, for details.
