Tinnitus Management in Lateral Skull Base Lesions.

J Neurol Surg B Skull Base 2019 Apr 30;80(2):125-131. Epub 2018 Nov 30.

Department of Otolaryngology-Head and Neck Surgery, The University of Michigan, Ann Arbor, Michigan, United States.

Tinnitus, the phantom perception of sound in the absence of a physical sound source, is a complex problem with multiple etiologies. While most commonly presenting in a subjective fashion caused by measurable hearing loss, other etiologies including lateral skull base tumors that encroach on middle and inner ear structures can lead to phantom sound perception as well. In addition to discussing the basic background of tinnitus, here we also review current theories of etiology that include central auditory and nonauditory neural mechanisms and potential treatments that range from sound therapy to medications to cognitive and behavioral therapies and cranial nerve and brain stimulation.

Intradural Extramedullary Spinal Neoplasms: Radiologic-Pathologic Correlation.

Radiographics 2019 Mar-Apr;39(2):468-490

From the Department of Neuroradiology, American Institute for Radiologic Pathology, 1011 Wayne Ave, Suite 320, Silver Spring, MD 20910 (K.K.K., R.Y.S.); Department of Radiology, Mayo Clinic, Rochester, Minn (K.K.K.); Uniformed Services University of the Health Sciences, Bethesda, Md (R.Y.S.); and Department of Radiology, Walter Reed National Military Medical Center, Bethesda, Md (R.Y.S.).

While intradural extramedullary spinal disease varies widely, identification of tumors in this location and their radiologic manifestations greatly facilitates narrowing of the diagnostic considerations. Meningioma and schwannoma are the two most common intradural extramedullary tumors, and both are associated with neurofibromatosis. Meningiomas are most common in the thoracic spine and show a strong female predilection and a clinical manifestation related to compression of the spinal cord or nerve roots. Read More

68Ga-DOTATOC PET/CT Differentiates Meningioma From Dural Metastases.

Clin Nucl Med 2019 May;44(5):412-413

Radiation Oncology, and.

A 77-year-old woman with history of breast cancer presented with 2 unclear dural contrast-enhancing lesions on MRI; differential diagnoses were breast cancer metastases and meningiomas. On Ga-DOTATOC PET/CT, the temporal lesion showed high uptake and was classified as meningioma, whereas the lesion at the falx showed barely any Ga-DOTATOC uptake uncharacteristic for meningioma and suggestive for a brain metastasis. After resection, histological specimens from the temporal lesion showed meningioma tissue with distinct SSTR2A expression, whereas the falx lesion revealed a breast cancer metastasis without significant SSTR2A expression.

AJNR Am J Neuroradiol 2019 Mar 28;40(3):433-439. Epub 2019 Feb 28.

From the Departments of Radiology and Biomedical Imaging (J.D.B., J.E.V.-M.)

Background And Purpose: Chordoid meningiomas are uncommon WHO grade II primary intracranial neoplasms that possess unique chordoid histology and follow an aggressive clinical course. Our aim was to assess the utility of qualitative MR imaging features and quantitative apparent diffusion coefficient values as distinguishing preoperative MR imaging metrics to identify and differentiate chordoid histology from other meningioma histologic subtypes.

Materials And Methods: Twenty-one patients with meningiomas with chordoid histology, which included both chordoid meningiomas (>50% chordoid histology) and meningiomas with focal chordoid histology (<50% chordoid histology) with available preoperative MR imaging examinations, including diffusion-weighted imaging, were identified.

Implications of Extracranial Distortion in Ultra-High-Field Magnetic Resonance Imaging for Image-Guided Cranial Neurosurgery.

World Neurosurg 2019 Feb 22. Epub 2019 Feb 22.

Department of Neurosurgery, University Medical Center Utrecht, Utrecht, The Netherlands.

Background: Ultra-high-field magnetic resonance imaging (MRI) of the brain is attractive for image guidance during neurosurgery because of its high tissue contrast and detailed vessel visualization. However, high-field MRI is prone to distortion artifacts, which may compromise image guidance. Here we investigate intra- and extracranial distortions in 7-T MRI scans. Read More

Intracranial cell lymphomas that mimic meningiomas: a case report to understand complex genetic, radiological and histopathological entities.

World Neurosurg 2019 Feb 21. Epub 2019 Feb 21.

Department of Neurosurgery, La Pitié-Salpétrière Hospital, Paris, France. Electronic address:

We describe a patient affected by a T-cell primary central nervous system lymphoma (PCNSL) with highly aberrant specific B-cell markers (CD79a and CD20). An unusual imaging presentation leads us to misdiagnose this lesion for a meningioma and perform surgical resection. We think that this infrequent anatomical presentation might be due to the aberrant specific B-cell markers (CD79a and CD20) genotype expression. Read More
