Abstract
Pineal hemorrhage only occurs in rare cases, and this known to have several different causes such as germ cell tumors, pineal cysts and vascular malformations, including the cavernous malformations. Pineal cavernous malformations are extremely rare: to date only fifteen cases have been reported worldwide. Although the diagnosis of pineal cavernous malformation is not easy because of the extreme rareness of this condition, the presence of this lesion can be suspected based on its typical radiological findings. Case 1. A 42-year- old man presented with a limitation in his upward gazing. Radiologic examinations showed acute hemorrhage in the pineal region. He underwent ventriculo-peritoneal (VP) shunting but the patient's condition deteriorated after the shunting surgery. We operated and totally removed the tumor and the hemorrhages via an occipital-transtentorial approach. Case 2. A 37-year-old man presented with diplopia. Radiologic examinations showed acute hemorrhage in the third ventricle. He underwent VP shunting, and after this procedure the diplopia was aggravated. We operated and totally removed the tumor and the hemorrhages via an occipital-transtentorial approach. If there is no doubt about the pineal cavernous malformation on MR imaging, we strongly recommend early surgical intervention without performing a risky biopsy. In this study, we describe our experiences for the diagnosis of cavernous malformations in the pineal region with special emphasis on the radiological aspects and the clinical course of this disease.
