Spotlight on Pleomorphic xanthoastrocytoma

Pleomorphic xanthoastrocytoma is an indolent (WHO grade I) tumor usually diagnosed in children and young adults. Location is most often temporal, and chronic epilepsy is the most common presenting symptom. It typically appears on imaging as an enhancing lesion with a cystic component in a superficial location. Tissue pathology is very aggressive in appearance, which is in sharp contrast with the typical benign clinical course seen in most cases. Treatment is with resection; other treatments are rarely warranted. Dr. Mintzer, an epilepsy specialist at Thomas Jefferson University, describes the characteristics of this unusual neoplasm, which is of equal interest to both the epileptologist and neuro-oncologist. Although this tumor type is rare, its appropriate diagnosis has considerable bearing on patient prognosis and is, therefore, crucial to avoid inappropriate patient management.

Spotlight on Meningiomas

Meningiomas are the most common intracranial tumors. Although most are benign, morbidity can be high, and in some cases the tumor is fatal. In this clinical summary, Drs. Wendy Sherman and Jeffrey Raizer of Northwestern University review the pathophysiology, presentation, and treatment of this tumor, including new prognostic indicators in atypical and malignant meningiomas.

Spotlight on Atrial myxoma

Atrial myxoma is the most common intracardiac tumor in adults. Its protean clinical manifestations make the clinical diagnosis difficult. It explains 0.4% of all strokes, but it can embolize systemically, cause systemic constitutional symptoms, or cause obstruction in the heart chambers. Its management requires surgical excision. In this update, Dr. Adrian Marchidann of State University of New York (SUNY) Health Science Center updates the data on acute ischemic stroke treatment with both intravenous and intra-arterial interventions.
