Intraventricular Ganglioglioma Presenting with Spontaneous Hemorrhage.

Intraventricular gangliogliomas presenting with spontaneous hemorrhage are rare. Due to high density of important tracts lateral to the ventricular atrium, the intraparietal trans sulcal approach is a good option to remove lesions in this location. These tracts are displaced and sometimes destroyed by the presence of large masses.

Cytomorphological features of blastic plasmacytoid dendritic cell neoplasm on FNA and cerebrospinal fluid cytology: A review of 6 cases.

Background: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematopoietic tumor that was once believed to be derived from natural killer cells and is now recognized as originating from precursors of plasmacytoid dendritic cells. It generally involves the skin and has an aggressive clinical course. Due to its highly malignant behavior, a fast and accurate diagnosis of this condition is of the utmost importance.

Revisiting Lipomatous Meningioma: A Case Report and Review of an Unusual Entity.

Lipomatous meningioma is a very rare subtype of metaplastic meningioma. It is defined by the presence of adipocytic-like cells, which are thought to result from lipid accumulation in meningothelial cells or true metaplastic change. We report a case of a lipomatous meningioma arising in a female patient complaining of recent seizures.
