A rare case of cavernous angioma located in the fourth ventricular floor occurred in a 44-year-old female complaining of occipital headache, vomiting, diplopia, and dysarthria. Computed tomographic scans demonstrated a high-density area in the fourth ventricle and slight hydrocephalus. Magnetic resonance (MR) imaging showed a mixed intensity mass on T2-weighted images and high- or isointensity regions on T1-weighted images. The tumor was totally removed and histologically diagnosed as cavernous angioma. Postoperatively, ataxic gait, nausea, and vomiting disappeared gradually. MR imaging was useful to accurately evaluate the anatomic relationship between the lesion and the brainstem.

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)

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)

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)

We reported a case of migraine with aura associated with meningioma. A 66-year-old female visited to our department in 1985, with occipital throbbing pain following visual hallucination and nausea. She had been diagnosed as migraine. CT scan, magnetic resonance image and angiography showed a right occipital tumor, which was totally removed in 1990. Postoperatively, the migraine disappeared completely. The tumor was histologically diagnosed as fibroblastic meningioma. We supposed that the migraine had been associated with meningioma. Although some previous papers reported correlation with brain tumor and migraine, as example of arteriovenous malformation or angioma, migraine associated with meningioma is very rare. In arteriovenous malformation, pathophysiology of migraine is unclear, but induction of circulatory disturbance in the distribution of the posterior cerebral, posterior communicating and basilar artery is supposed. And then a space occupying lesion in the occipital lobe is possible to cause in the circulatory disturbance of the posterior cerebral and basilar artery. In the diagnosis of migraine, we should consider its relation to brain tumors, such as meningioma.

We reported a case of cavernous angioma in the middle cranial fossa, which was diagnosed with magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). The patient was a 56-year-old female, who presented with sudden onset right-sided headache with nausea. Her neurological findings were normal. On CT scan a high density area with a surrounding thin low density area was shown in the right posterior temporal region without contrast enhancement. Cerebral angiography of the left vertebral artery revealed only a small stain at the end of the right posterior temporal artery. On T2-weighted MRI after one month, the same region exhibited a central area of mixed signal intensities surrounded by a rim of decreased signal. MRA showed an area with remarkable 10mm mass with some contiguous vessels in the right posterior temporal region. That mass was resected operatively. It's pathological diagnosis was cavernous angioma. For diagnose of cavernous angioma, MRI and MRA were very useful. The specificity of these methods are superior to better than CT or angiography.

A 49-year-old female had experienced headaches and nausea for 2 months. Neurologic examinations showed mild blurring of the optic disc and limitation of ocular movement. Magnetic resonance imaging (MRI) studies disclosed a mass in the central and right paramedian mesencephalon with rostral extension to the third ventricle and the right side of the thalamus. This tumor had a peripheral low signal ring and a heterogeneous central signal on T1 weighted images. The findings were thought to be consistent with a cavernous hemangioma. The clear anatomic boundary of the lesion was defined by MRI enabling removal of the mesencephalic cavernoma. The patient headache remained well with no neurologic symptoms in the 3 years following the operation.

A 35-year-old male was admitted with headache, nausea, and vomiting persisting for 2 days. Computed tomography (CT) revealed a left chronic subdural hematoma. Cerebral angiography demonstrated cerebral venous sinus thrombosis (CVST). He had presented with a subcutaneous mass involving the neck at age 2 years, which was shown to be a cavernous angioma, and thereafter shown signs of consumptive coagulopathy with systemic multiple hemangiomas. Burr hole aspiration of the hematoma was performed. Seventy-two-hours later, he developed clouding of consciousness and right hemiparesis. CT revealed a fresh hematoma in the operated subdural cavity and hemorrhagic diathesis manifested. A frontotemporoparietal large craniotomy was performed to remove the hematoma. Extensive electrocauterization was required. He had a satisfactory postoperative course. Collateral venous pathways, resulting from the CVST due to systemic multiple hemangiomas, may have caused hemodynamic stress in the bridging veins which subsequently induced chronic subdural hematoma.

We report a case of an oligodendroglioma associated with a cavernous angioma. The patient, a 20-year-old man with an 8-year history of epileptic seizures, presented an acute onset of headache, nausea, and vomiting. Computerized tomographic scan and angiogram revealed multiple vascular malformations in both hemispheres including a cystic hemorraghic lesion with a perifocal edema attributing to a mass effect. Repeated puncture of the cyst failed to give improvement of elevated intracranial pressure. At surgery, the cyst and the underlying lesion were excised and found to be oligodendrocyte-rich tissue with malformed vascular tissue. Final histological examination revealed an oligodendroglioma associated with a cavernous angioma. As concurrence of oligodendroglioma and vascular malformation is rare, this case raises a broad range of differential diagnoses such as reactive oligodendroglial gliosis due to a vascular malformation, unusual vascularity of an oligodendroglioma as well as other kinds of cerebral tumors or malformations. The diagnostic difficulties as well as the pathogenetic and pathological significance of the concurrence of an oligodendroglioma and cavernous angioma are discussed.

Recent advances in neuroradiology have enabled us to approach cavernous angioma in the brain stem. A case of large cavernous angioma, which was located in the pontomedullary junction, was removed surgically. A 24-year-old female was admitted with occipitalgia, dizziness, nausea, gait disturbance. On neurologic examination, the patient had right hemiparesis, slight right facial palsy and paresthesia, right hemiparesthesia, dysphagia. T1 weighted Gd enhanced MRI revealed a mixed intensity lesion. These findings were thought to be consistent with a cavernous angioma. Follow up MRI findings demonstrated progressive increase in cavernous angioma. Vertebral angiograms showed a mass sign and a venous angioma in the midline of the pontomedullary junction. Therefore, the operation was performed in an attempt to remove the cavernous angioma through the midline of the fouth ventricle. The operation was performed under monitoring of electromyogram of facial muscle and external ocular muscle. The cavernous angioma was removed totally, and addition neurogical deficits were minimal.
