Four cases of venous angioma, one cerebral and three in the cerebellum, are reported. Case 1. A 50-year-old woman who had a sudden attack of headache and disorientation was admitted to the Mitsui Memorial Hospital. Neurological examination revealed slight disorientation, mild motor aphasis and right hemiparesis. Plain CT scan on admission showed a left frontal hematoma. Left cerebral angiomas demonstrated a caput-Medusae-like lesion which consisted of numerous small veins and drained into one single enlarged vein. Enhanced CT scan taken 12 days after the attack demonstrated a linear enhancement next ot the hematoma. Left frontal craniotomy was performed, and the hematoma was evacuated. In the next step, coagulation and resection of the major part of the angioma was attempted. However, this caused significant swelling of the adjacent brain and the angioma had to be resected totally including intervening normal cerebral tissue. Postoperatively, the patient became worse with significant hemiparesis and severe motor aphasia. After intensive rehabilitation treatment, she recovered gradually and was discharged on foot with moderate speech disturbances. Histological examination revealed a typical venous angioma with hyalinization of vessel wall. Case 2. A 55-year-old woman with a 9 year history of vertigo and headache was admitted to our hospital because of sudden onset of numbness in her right lower limb. Enhanced CT scan revealed a small nodular high density lesion and an old hematoma in the right cerebellar hemisphere. Vertebral angiograms demonstrated a single abnormal vein with some small veins in the right cerebellum. Right suboccipital craniectomy was performed and the blood clot was removed. The abnormal veins were electro-coagulated. The postoperative course was uneventful and the patient was discharged with no neurological deficit. Case 3. A 31-year-old man was admitted to our department with 9 month history of nausea and vertigo attack. Enhanced CT scan demonstrated a large nodular high density lesion in the left cerebellar hemisphere. Vertebral angiograms showed a typical caput-Medusae-like venous angioma. The patient had no evidence of hemorrhage and was discharged without surgery. Case 4. A 36-year-old man who had two attacks of nausea and headache was admitted to the Mitsui Memorial Hospital. Enhanced CT scan showed a linear high density lesion in the right cerebellar hemisphere. Vertebral angiograms disclosed a typical venous angioma in the right cerebellum. This patient also had no attack of bleeding and was discharged without operation.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of cavernous angioma at the lateral wall of the third ventricle which was totally removed with interhemispheric trans-lamina terminalis approach is reported. A 40-year-old male had a slowly progressive onset of partial diabetes insipidus and headache with no neurological deficit . CT scan revealed a high density area at anterior third ventricle. The tumor was diagnosed ectopic pinealoma because of CT findings and clinical symptoms. Irradiation and chemotherapy ( RAFP therapy) was performed to this lesion. After two months, his clinical symptoms disappeared. CT scan showed decrease of the density of the region at this point. He was discharged with no symptom. After a half year, he suddenly complained of right homonymous hemianopsia with headache. CT scan showed that the high density area became larger to left posterior than that of half year before. Left carotid angiogram showed no mass lesion and no abnormal vessel. Operation was performed with interhemispheric trans-lamina terminalis approach using bifrontal craniotomy. Operative findings revealed that the tumor situated at the lateral wall of the third ventricle, had rough surface with reddish colour, and old and fresh blood clots inside the tumor. The tumor was carefully dissected without brain damage and was totally removed. The histological findings was compatible with cavernous angioma. Post-operative CT scan showed no high density area. He was discharged with no neurological deficit without right homonymous hemianopsia. Cavernous angioma of anterior third ventricle is very rare.(ABSTRACT TRUNCATED AT 250 WORDS)

A series of 15 angiographically cryptic, histologically proved, cerebrovascular malformations occurred. Nine patients were admitted to the hospital with evidence of recent neurological deterioration or onset of headache. Six patients had convulsions. Computed tomographic scan and surgical exploration disclosed a substantial cerebral hematoma in eight instances. The pathological diagnosis was arteriovenous malformation in 11 cases, cavernous angioma in three, and venous angioma in one. Histological evidence of previous microhemorrhage was present in the majority of the specimens, including the patients who had seizures. A change in neurological status or onset of seizures probably indicates recent hemorrhage in cryptic cerebrovascular malformations.

Spontaneous intracerebral hematomas can be diagnosed immediately and localized exactly by the means of cranial computerized tomography. The occipital lobe is a relatively rare site of hypertensive hematomas which are the most frequent etiologic group. Out of 264 patients with intracerebral hematomas ion cranial computerized tomography we found the occipital lobes affected in 24 cases i.e. 9%. 116 patients with intracerebral hematomas treated in the neurologic clinic demonstrated in 15 cases (13%) occipital localization. In 7 patients bleedings were of hypertensive origin, in 4 cases etiology was unknown, in one case it originated from an arteriovenous angioma and in 3 cases congophilic (amyloid) angiopathy was the basic disease. In smaller occipital hematomas the clinical symptoms are relatively mild, mainly consisting of acute headache and hemianopsia. If the hematoma is limited to the occipital lobe the prognosis is favorable both with or without neurosurgical treatment.

The AA relate a case of a complex malformation of the AICA characterized by aneurysm of the internal auditory artery developed inside the internal acoustic channel associated with an angioma fed by the cerebellar branch of the same artery. During a long period with dizziness, tinnitus, headache in the occipital region, mild sensoneural retrocochlear hearing loss a subarachnoid hemorrhage occurred. The vascular malformations were visualized by a vertebral angiography and the axial projection resulted to be the most important clue. The AA report the case for its rarity and emphasize the vascular origin of certain unexplained kinds of vestibular syndromes in young patients.

A 32-year-old man with a history of delayed puberty and obesity was seen initially with bitemporal hemianopsia and headache in 1974. Neuroradiologic studies showed a mass in the chiasmatic cistern and hypothalamus. Surgical exploration of the chiasm was unrevealing. Slowly progressive memory loss and intellectual impairment developed. Necropsy in 1978 disclosed a large cavernous hemangioma in the diencephalon.

A 56-year-old male presented with a posterior fossa cavernous angioma manifesting as persistent headache with mild neck stiffness. Lumbar puncture revealed subarachnoid hemorrhage (SAH). Repeated four-vessel angiography failed to identify the source of the SAH. Magnetic resonance (MR) imaging demonstrated multiple small lesions in the posterior fossa and cerebral hemispheres, and the SAH. A mass arising from the biventral lobule of the right cerebellar hemisphere extended exophytically into the cisterna magna with intratumoral hemorrhage. These findings were compatible with the presumptive diagnosis of SAH from the mass at the right biventral lobule. The lesion was totally removed through a suboccipital craniectomy without sequelae. The histological diagnosis was cavernous angioma. Intracranial cavernous angioma presenting only as SAH has never been reported before. The use of MR imaging in establishing the diagnosis of vascular malformations is emphasized, particularly when neither computed tomography nor angiography can adequately visualize the origin of SAH.

Spinal cavernous hemangioma is rare, and it is extremely rare for cavernous hemangioma to develop in the cauda equina. There has been only one report of hydrocephalus associated with cavernous hemangioma in the cauda equina. We report a case of cavernous hemangioma in the cauda equina diagnosed on the basis of the headaches due to hydrocephalus. A 67-year-old man was being treated for Parkinson's disease because of tremor of both upper extremities for several years. In December 1991 he complained of occasional headaches. On February 15, 1992 the headaches became severe and frequent, with nausea and vomiting, and his gait became unsteady. Four days later he came to our hospital. Neurological examination revealed fine finger tremor and truncal ataxia. Computerized tomography scanning and magnetic resonance imaging of the head revealed ventricular enlargement, but there were no mass lesions obstructing the cerebrospinal fluid pathway. Lumbar puncture at the L3-L4 level yielded bloody cerebrospinal fluid, and the pressure had increased to 410 mmH2O. Cerebral angiography showed no abnormal findings. Magnetic resonance imaging of the lumbar spine demonstrated an intradural tumor at the level of vertebral body L2. Spinal angiography showed no evidence of abnormal vascularity in the mass at the L2 level. On March 10, 1992, laminectomy at three levels, L1 to L3 was performed, and a well-defined blueberry-like intra-cauda equina tumor 1 cm. in diameter, was removed. One spinal nerve root passed through the tumor. The pathological diagnosis was cavernous hemangioma. After removal of the tumor, the patient's headaches improved, and a follow-up computerized tomography scan six months later showed normal ventricle size.(ABSTRACT TRUNCATED AT 250 WORDS)

A 54-year-old female presented with a huge mixed cavernous angioma and astrocytoma in the hypothalamus manifesting as headache, visual field defect, gait disturbance, and convulsion. Radiological studies revealed a huge suprasellar tumor encasing all the major cerebral vessels. Craniotomy disclosed a hemorrhagic tumor poorly demarcated from the surrounding brain which was partially removed. Histological examination of the operative specimen revealed cavernous angioma with low grade glioma in the periphery. The residual tumor responded to radiation therapy remarkably well. An autopsy conducted 3 years later revealed a small hypothalamic astrocytoma with abundant vasculature.

A case of an extra-axial cavernous angioma of the cisterna magna is described. The clinical presentation, radiographic features, treatment of that unusual location in the posterior fossa are discussed. The patient is a 31 years old man admitted for the sudden onset of occipital headache and instability. A CT scan demonstrated a slightly calcified lesion, minimally enhanced after intravenous injection of a contrast agent, located within the posterior fossa. A T2-weighted MR image showed a well circumscribed mass, located between medulla oblongata and left cerebellar tonsil, of mixed signal intensity surrounded by a rim of decreased signal intensity related to the presence of hemosiderin. Cerebral arteriography was normal. A medial suboccipital craniectomy was performed, with the patient in the ventral position, in which a 1.5 x 1 cm solid dark-red mass was encountered arising from the cisterna magna and was easily removed "en bloc". The operative extra-axial aspect of that lesion was evident excluding a medulla oblongata tumor protruding into the cisterna magna. Histologically, the lesion was a cavernous angioma consisting of numerous vascular channels with collagen fibrous walls filled with fibrin thrombi and hemosiderin. Few elastic fibers were found in vascular walls. The patient's post-operative course was unremarkable.
