We reported a rare case of multiple cavernous angioma accompanied with a convexity meningioma. A 41-year-old female developed generalized convulsion on October 8, 1985. Plain computed tomography (CT) scan revealed a round heterogeneous density mass in the right parietotemporal region, which was homogeneously enhanced. Angiography demonstrated a tumor stain fed by the right angular artery and the posterior branch of the right middle meningeal artery. Total removal of the tumor was performed. Since histological examination disclosed meningothelial cells, whorl formation, polymorphism and necrotic tissue, she received radiation therapy (total 50Gy) under the diagnosis of anaplastic meningioma. On November 10, 1988, she suddenly developed headache, nausea, motor weakness and homonymous hemianopia on the left side. CT scan revealed intracerebral hemorrhage (ICH) near the region where the meningioma used to be. Magnetic resonance image (MRI) demonstrated a high intensity mass at T1-weighted image and mixed intensity mass at T2-weighted image. Furthermore, there were multiple low intensity spotty lesions at the cerebral and cerebellar hemisphere in T1 and T2-weighted image. A few parts of these lesions showed central high intensity cores and perifocal low intensity areas, which were called ring formations or reticulated cores with black rims. The multiple lesions could not be detected by CT scan. ICH was evacuated. Histological examination revealed no specific pathology except necrotic tissue around the hematoma wall. Diagnosis of radiation necrosis was made. On October 25, 1992 she suddenly complained of left hemihypesthesia. CT scan demonstrated two high density spotty areas at the left caudate head and right thalamus. MRI showed these two lesions as reticulated cores with black rims.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report a case of a 53-year-old woman who developed symptoms and signs of compression of the left medulla oblongata by the elongated and curved left vertebral artery with normal diameter. Twelve days before admission to the hospital, the patient suddenly noticed severe occipital-nuchal headache and nausea with vomiting, while she was unloading a burden. Neurological examination revealed left facial hyperalgesia, right hemihypesthesia and mild right hemiparesis. Hoarseness was observed, but the movement of the uvula and tongue was normal. Hypertension was noticed (180/100). Cerebral and vertebral angiography revealed no aneurysm, but demonstrated an elongated and curved V4 portion of the left vertebral artery with normal diameter. Coronal plain of T2 weighted image of MRI and CT scan with metrizamide administered into the CSF, clearly demonstrated an elongated and curved left vertebral artery compressing the ventro-lateral portion of the left medulla oblongata, neurovascular decompression of the V4 from the medulla oblongata was performed. Through the operating microscope, it was observed that the elongated and curved V4 portion of the left vertebral artery with normal configuration was compressing the left medulla oblongata ventro-laterally, making a compression notch at the outlets of the cranial nerves IX and X. Transposition of the V4 portion was impossible. Some pieces of Taflon felt, thick enough to prevent the pulsatile movement of the V4 from compressing the medulla oblongata, were inserted between the V4 and the medulla oblongata. Two months after the operation, the patient's right hemiparesis and sensory disturbances were gradually improving and her blood pressure had become normal. The authors emphasize that, among patients with symptoms and signs of compression of the medulla oblongata, there is at least one patient for whom neurovascular decompression was an effective treatment.
