Tumors in the temporal horn of the lateral ventricle as a cause of epilepsy.

Three neoplastic lesions located in the temporal horn of the lateral ventricle were diagnosed after the onset of seizures. Neither hydrocephalus nor temporal horn entrapment were present. The complete surgical removal of the tumor resulted in the disappearance of the epileptic episodes in 2 cases; the third patient refused surgery, and his lesion appears unmodified after a 3-year follow-up.

Expression of cyclooxygenase-2 and its correlation with vasogenic brain edema in human intracranial meningiomas.

COX-2 expression was evaluated in intracranial meningiomas, relating this molecule to grade, vasculature, VEGF and brain edema. Fifty-six tumors were evaluated for COX-2 and VEGF expression and for microvessel density. In 34/56 cases, the edema was evaluated by CT scan.

Primary intra-diploic meningioma in a child.

Background: Primary intra-diploic meningiomas are uncommon in childhood and, at the clinical onset, may be confused with other and more frequent bone tumours because they lack specific clinical and radiological characteristics. Surgery is indicated not only to remove the lesion but also to obtain an accurate histological diagnosis.

Case Report: We report the case of a young girl who presented with a recently developed subcutaneous hard mass in the left pterional region.

Expression of endothelin 1 and its angiogenic role in meningiomas.

Meningiomas are one of the most frequent central nervous system tumours. Although slow-growing at times, they continue to be a cause of morbidity and mortality. The endothelin (ET) family consists of three isoforms: ET-1 is the most abundant one.
