Pineal hemorrhage
It is very important to perform the differential diagnosis because pineal hemorrhage is very rare and it may be associated with many different causes. The possible causes of pineal hemorrhages are pineal region tumors 1) 2) 3) 4) 5) 6) 7).
Vascular pineal malformation and pineal cysts 8) 9) 10).
Various pineal tumors have been reported to cause intra-tumoral hemorrhage including ganglioglioma 11) pineocytoma 12) choriocarcinoma, 13) 14) meningioma 15) and hemangiopericytoma. 16) Embryonal carcinoma and metastatic melanoma are also included in the differential diagnosis 17) 18).
