A case of an hemorrhagic cavernous hemangioma of the optic chiasma and the adjacent optic nerve in a 23-year-old woman is reported. The visual disturbance has subacute onset following a sudden lateralized headache. Through a fronto-pterional approach, an intrachiasmal hematoma was evacuated. A small cavernous hemangioma was found in the hematoma cavity, and it was totally removed. Visual symptoms improved slightly postoperatively. Cavernous hemangioma involving the optic nerve and chiasma is extremely rare. Only five similar cases have been reported previously.

A young man is described in whom in full health sudden violent headaches and loss of consciousness developed. After admission to hospital a complex of clinical signs was observed indicating brain stem lesion. Computerized tomography of the head and vertebral arteriography demonstrated arteriovenous haemangioma on the left side of the brain stem. The malformation was supplied by the anterior inferior cerebellar artery. The patient did not consent to operation, after several months of rehabilitation his clinical condition improved greatly.

This article reported a familial occurrence of intracerebral cavernous angioma in four members of one generation diagnosed by X-ray CT, MRI or operative specimen. Case 1, a 34-year-old female, was examined just after an episode of sudden convulsive seizure. On examination, she had a cutaneous angioma without any neurological deficit. X-ray CT revealed a high density mass lesion in the left frontal lobe, and MRI demonstrated a mass lesion in the chronic stage with an old hematoma circumscribed by hypointensity ring indicating peripheral hemosiderosis. Complete excision was carried out and a diagnosis of cavernous angioma was made after histological examination. Case 2, the 37-year-old brother of Case 1, suddenly developed left hemiparesis and hypesthesia with severe headache. X-ray CT revealed a high density mass in the right parietal lobe and two other calcifications. The right parietal lesion was excised and a histopathological diagnosis of cavernous angioma with intracerebral hematoma was made. Case 3, the 49-year-old sister of Case 1, suddenly fell into a coma and was admitted immediately. X-ray CT revealed a large pontine hemorrhage. She died on the 4th day of hospitalization without operative treatment. Necropsy was not carried out. Case 4, the 39-year-old sister of Case 1, was asymptomatic, however, she was examined on the supposition of a familial occurrence of intracerebral cavernous angioma. On examination, it was found she had multiple cavernous angioma without any neurological deficit. X-ray CT revealed parietal intracerebral calcification. MRI demonstrated a mass lesion with peripheral hypointensity ring in the right parietal lobe, and another small lesion in the pons.(ABSTRACT TRUNCATED AT 250 WORDS)

We reported a 41-year-old male with paramedian thalamic and midbrain infarcts due to cerebral embolism from bilateral pulmonary arterio-venous fistula and primary medullary hemorrhage. The patient had an episode of sudden onset consciousness disturbance with left Weber's syndrome (right hemiplegia and left oculomotor palsy) and vertical gaze palsy at age of 23. He noticed numbness in the left hand and the left half body under clavicular when he had got up in a morning at age 41. He had headache and left tinnitus on second and third days, and on the 3rd and 4th days, he experienced nausea. He had severe hiccup persisting from the 6th to the 13th days. The 23rd days he was admitted to our hospital. He showed dysesthesia and paresthesia in left half body under clavicular, dysesthesia in left hand and vertical gaze palsy and convergence disturbance. MRI performed on the 18th and 24th days, disclosed hyperdense mass in T1 and T2-weighted images in dorsal site of medulla, but the 70th days MRI showed no abnormal lesions. Therefore we diagnosed the high intensity mass as primary medullary hemorrhage. Cerebral angiography showed no abnormal vasculature. Many members of his family had history of sever nasal bleeding. He had skin hemangioma and mucosal hemangioma in esophagus, stomach, colon and rectum, and bilateral pulmonary arterio-venous fistula which had been operated at age 39. His mother also had skin hemangioma and pulmonary arterio-venous fistula. Therefore this family was diagnosed Rendu-Osler-Weber syndrome (hereditary hemorrhagic telangiectasia). MRI also disclosed multiple cerebral infarctions in bilateral thalamus, left cerebral peduncle and left cerebellar hemisphere.(ABSTRACT TRUNCATED AT 250 WORDS)

A cavernous angioma of the right optic tract in a 35-year-old man is presented. The patient suffered from headaches and had a left homonymous visual field defect after subarachnoid haemorrhage and an intracerebral haematoma in the right temporomedial region, revealed by computed tomography (CT). Follow-up CT showed a small contrast-enhanced lesion in the right suprasellar and parasellar cistern. Angiography on three occasions did not reveal a vascular lesion. Magnetic resonance imaging was helpful both for diagnosis and planning surgical therapy. It showed typical signs of a cavernous angioma of the right optic tract; the diagnosis was confirmed by surgery and histological examination. This appears to be the first reported case of a cavernous angioma of the optic tract.

We present a patient who experienced sudden onset of orbital headache, visual loss and bitemporal visual field defect. MRI of the optic chiasm suggested a diagnosis of haemorrhage and hence a vascular malformation. Pterional craniotomy revealed an intrachiasmatic haematoma with a cavernous angioma. The malformation was totally excised and vision improved after surgery. The syndrome of chiasmal apoplexy is discussed.

Cerebral venous angiomas are considered by many investigators as infrequent and incidental. Our experience, however, has been different. Since 1975, we have compiled a group of 21 patients with 23 venous angiomas. Nine patients (43%) presented with intracranial hemorrhage, and two in this group had recurrent hemorrhage. Surgical extirpation of the venous angioma was performed in all nine cases. An additional resection of a frontal venous angioma was performed in a woman with intractable seizures and headache. We experienced limited morbidity and no mortality. Although venous angiomas may be uncommon clinically, they have a significant potential for hemorrhage, and particularly, rehemorrhage if left untreated.

A 23-year-old pregnant woman presented with sudden diplopia, ataxia, hemiparesis, and headache secondary to a brain stem hemorrhage. Magnetic resonance imaging (MRI) revealed a hematoma associated with a probable cavernous hemangioma of the rostral brain stem. In this report, we discuss the MRI findings leading to the preoperative diagnosis, as well as the surgical techniques involved in the successful resection.

Thrombosed arteriovenous malformations (AVMs) are the predominant type of occult vascular malformation and do not seem to differ significantly in clinical or radiographic presentation from other types of occult vascular malformations. Thrombosed AVMs and occult vascular malformations occasionally present with symptoms secondary to subacute or occult hemorrhage that requires operation. The histopathology of thrombosed AVMs and occult vascular malformations does not seem to have prognostic significance. Five patients with histologically verified thrombosed AVMs are reported. Two patients had previous incomplete resection of histologically proven thrombosed AVMs and presented with recurrence and bleeding. Two patients presented with seizures and headaches, and one patient presented with hemiparesis and headache. All histology specimens had evidence of hemorrhage. The pathological findings of these lesions seem variable; two specimens contained a mixture of cavernous angioma and AVM. Two previously resected lesions had been defined histologically as thrombosed AVMs. Successful excision of the lesions was accomplished in four patients, and one patient had stereotactic biopsy. The magnetic resonance imaging characteristics of lesions seem to add a degree of specificity over computed tomography and angiography. We have found that the literature poorly describes the natural history and histology of these lesions. Conservative management for seizures and headaches due to thrombosed AVMs may not be warranted because of a propensity for hemorrhage and recurrence.

Angiosarcoma is a rare malignant tumor originating from vascular endothelial cells. We have experienced a case of 17-year-old man, who had angiosarcoma in the pineal region and the liver. Patient's initial symptom was headache and CT scan revealed a high density mass in the pineal region with obstructive hydrocephalus. After the radiation therapy, the tumor was disappeared completely on CT scan. One year later, he developed abdominal pain, and CT scan and angiogram revealed multiple angioma like lesions in the liver. The mass in the pineal region showed concomitant regrowth, and finally, the patient was died of abdominal hemorrhage. At autopsy, pineal tumor and hepatic tumor were both angiosarcomas, although it was uncertain which was the original tumor.
