Antiphospholipid syndrome and neurofibromatosis type I: a coincidence or new association?

Arq Bras Oftalmol 2019 Mar-Apr;82(2):155-157

Department of Neuro-radiology, Sheikh Khalifa Hospital, Abu Dhabi, UAE.

Numerous studies have reported on structural vascular anomalies and ischemia associated with neurofibromatosis type 1 that are thought to stem from dysfunction of neurofibromin, the neurofibromatosis type 1 protein. Documented cases of associated antiphospholipid syndrome fulfilling the accepted diagnostic criteria are exceptionally rare, with only three cases reported in the literature. Here, we report on a patient with neurofibromatosis type 1 and a history of spontaneous abortions presenting with sudden vision loss in the right eye and swelling of the optic nerve head. Read More

Imaging and diagnostic advances for intracranial meningiomas.

Neuro Oncol 2019 Jan;21(Supplement_1):i44-i61

Center for Skull Base and Pituitary Surgery, Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

The archetypal imaging characteristics of meningiomas are among the most stereotypic of all central nervous system (CNS) tumors. In the era of plain film and ventriculography, imaging was only performed if a mass was suspected, and their results were more suggestive than definitive. Following more than a century of technological development, we can now rely on imaging to non-invasively diagnose meningioma with great confidence and precisely delineate the locations of these tumors relative to their surrounding structures to inform treatment planning.

Pathological laughter as an early and unusual presenting symptom of petroclival meningioma: A case report and review of literature.

World Neurosurg 2018 Dec 13. Epub 2018 Dec 13.

Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Rae Bareli Road, Lucknow, India.

Background: Pathological laughter is inappropriate, involuntary and unmotivated laughter episodes which may or may not be associated with mirth or amusement. Though associated with many diffuse brain pathologies, its association with intracranial focal mass lesions causing ventrolateral brainstem compression like petroclival meningioma is very rare. The exact pathophysiology of this interesting and unusual clinical symptom is unknown but probably involves disinhibition and release of the so-called coordination center located in the upper brainstem due to compression by the tumor.

Proceedings of the 2018 next-generation Gamma Knife research meeting.

J Neurosurg 2018 Dec;129(Suppl1):5-9

7Department of Radiation Oncology, Sunnybrook Health Sciences Centre, University of Toronto, Ontario, Canada.

In order to determine what areas of research are a clinical priority, a small group of young Gamma Knife investigators was invited to attend a workshop discussion at the 19th International Leksell Gamma Knife Society Meeting. Two areas of interest and the need for future radiosurgical research involving multiple institutions were identified by the young investigators working group: 1) the development of additional imaging sequences to guide the understanding, treatment, and outcome tracking of diseases such as tremor, radiation necrosis, and AVM; and 2) trials to clarify the role of hypofractionation versus single-fraction radiosurgery in the treatment of large lesions such as brain metastases, postoperative cavities, and meningiomas.

Multiparametric Magnetic Resonance Imaging in the Assessment of Primary Brain Tumors Through Radiomic Features: A Metric for Guided Radiation Treatment Planning.

Cureus 2018 Oct 8;10(10):e3426. Epub 2018 Oct 8.

Radiation Oncology, University of Mississippi Medical Center, Jackson, USA.

Purpose The definition of radiotherapy target volume is a critical step in treatment planning for all tumor sites. Conventional magnetic resonance imaging (MRI) pulse sequences are used for the definition of the gross target volume (GTV) and the contouring of glioblastoma multiforme (GBM) and meningioma. We propose the use of multiparametric MRI combined with radiomic features to improve the texture-based differentiation of tumor from edema for GTV definition and to differentiate vasogenic from tumor cell infiltration edema.
