Choroid plexus meningioma: Report of two cases.

Objective. Our intention is to show our clinical and pathologic experience with common tumor found in unusual and rare location. Methods. Case 1. 58 years old female patient was admitted to the hospital for acute psychosis with paranoid ideas and jealousy. CT and MR showed an oval tumor process, about 3 cm in diameter, situated at the trigone of the right lateral ventricle, with dilatation of occipital horn of the ventricle. Left-sided incomplete homonymous hemianopsia remained after regular postoperative course. Case 2. 71 years old, hypertensive and diabetic, female patient, last five years on psychiatric treatment for psychosis. Patient passed through neurologic and radiologic diagnostics because suspicion of brain trauma that find out an expansive process at trigone of left lateral ventricle 4 cm in diameter with dilatation of occipital horn but without central structures displacement and without sings of hypertensive hydrocephalus. During postoperative course the patient developed the deep vein thrombosis and died because of massive pulmonary thromboembolism. Results. Histologic diagnosis of meningioma was made on fresh frozen sections during the operation in both cases. Fibroblastic type of meningioma was diagnosed in both cases. Immunohistochemical staining for EMA, Vimentin, S-100 and progesteron receptors showed positivity in both cases while immunohistochemical staining for GFAP, CKAE1/AE3, CKMNF 116 and CEA were negative. Estrogen receptors showed weak and focal nuclear positivity in the first case. Conclusion(s). Choroid plexus meningioma in this location becomes most diagnostically challenging because certain variants of meningioma may mimic other tumors found in this location and meningioma may be forgotten in the differential.
