Meningioma in 16 Dogs

Intracranial meningioma in dogs and cats: a comparative review.

Meningiomas are extraaxial tumors that arise from the arachnoid layer of the meninges. Seizures are the most common clinical sign in dogs; cats more often present with mentation changes, vision loss, and gait abnormalities. Meningiomas in both species grow slowly and have an insidious onset of clinical signs. These tumors are more likely to be malignant in dogs. Surgery, radiation, and chemothe...

Large Meningioma in an Infant

Abstract Background Histologically confirmed meningiomas in first year of life are quite rare. However, review of the sporadic cases in the literature reported meningioma in infants. Those have unique features in common. Case presentation An 11 month-old Iranian male infant presented with a several weeks history of decrease in movement of his right sided upper and lower extremities. Brai...

Histiocytic meningioma: A distinctive subtype of meningioma?

Meningioma with extensive histiocytic changes is rare. We describe a case of histiocytic meningioma which occurred in a 55-year-old woman. The patient had a progressive headache and a decline in fine motor coordination and memory for the past four years. Magnetic resonance imaging demonstrated a well-demarcated, dura-based and contrast-enhancing mass lesion in the right superior frontoparietal ...

Prognostic Factors in Meningioma

An Immunohistochemical Study Of P63 Protein Expression In Meningioma

  Background and Objective: Histological grading has prognostic and therapeutic implications in meningioma. However, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. P63 gene is a novel P53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. In this stu...
