A 69-year-old man suffered from dizziness and nausea after work, and was admitted to our hospital on the next day. On admission, he showed bilateral horizontal nystagmus and left hemiparesis. On the 3rd day he vomited frequently, and the dizziness became worse. Bilateral horizontal and upward gaze palsy and bilateral facial nerve palsy were observed. Brain MRI on the 5th day disclosed bilateral upper medial medullary infarction that extended to the pontomedullary junction. Cerebral angiography on the 13th day revealed occlusion of the right vertebral artery. This case did not show typical medial medullary syndrome. The mechanism was unknown, but similar cases were reported. Recently, many cases of medullary infarction are reported with the progress of MRI technology. It is suggested that the addition of the new concepts on the conventional syndromes of medullary infarction is necessary.

Medial medullary infarctions (MMI) were reported in less than 40 patients with satisfactory clinicotopographic documentation. We studied seven patients with MRI-proven acute MMI seen in two neurologic departments over a 5-year period (1990-1994). MMI represented less than 1% of ischemic strokes in the posterior circulation. Five patients had an infarction above the pyramidal decussation. All patients had contralateral hemiparesis and lemniscal sensory loss, accompanied by ipsilateral lingual palsy (Dejerine's syndrome) in three. Two patients had infarction below the pyramidal decussation, with ipsilateral hemiparesis and lemniscal sensory loss. Accompanying symptoms and signs of MMI were vertigo and nausea (n = 5), mild ipsi- or contralateral decrease in pain sensation (n = 6), headache (n = 4), ipsilateral limb ataxia (n = 6), contralateral truncal lateropulsion (n = 5), mild ipsilateral ptosis (n = 4), nystagmus (n = 4), dysarthria (n = 3), and somnolence (n = 2). Presumed causes of MMI were stenosis, occlusion or dissection of the ipsilateral vertebral artery (n = 5), and cardioembolism (n = 1). Outcome at 3 months was favorable in five patients. In conclusion, the clinical features of MMI are more heterogeneous than commonly thought, whereas its etiology seems fairly constant (vertebral artery disease).

Twenty-two patients with supratentorial malignant gliomas were treated postoperatively with concurrent intracarotid chemotherapy and radiation therapy. There were seven women and 15 men with a median age of 56 years (range, 22-69) and median performance status (Karnofsky score) of 70 (range, 40-90). In all except two cases, histologic studies confirmed malignant glioma. All patients were irradiated with a cobalt 60 equipment. They should have received 45 Gy to the whole brain plus a 15-Gy coned-down boost to the tumor area. Chemotherapy consisted of cisplatin infusion at a dose of 60 mg/m2 on days 2, 22, and 42. Treatment was interrupted in two patients because of progressive disease and voluntary withdrawal in one patient each. In all, 63 courses of cisplatin infusion were administered, all at full dose. Two patients achieved a partial response, and nine had stable disease. Toxicities included nausea/vomiting in nine patients (41%) and transient hemiparesis, confusion, diarrhea, and thrombophlebitis in one patient each. Median time to progression was 26 weeks (range, 4-226+), and median survival was 58 weeks (range, 14-226+). In conclusion, the present study suggests that intracarotid cisplatin administered concurrently with radiation does not improve the therapeutic index in malignant gliomas.

We present a case of right middle cerebral artery occlusion after a controlled ovarian hyperstimulation regimen and cryopreserved embryo transfer (ET) in a previously healthy 22-year-old woman. The patient suffered from nausea and progressive abdominal distension 8 days after ET. Under the diagnosis of ovarian hyperstimulation syndrome, she was treated with hypertonic solution, albumin infusion, and paracentesis, with some improvement. Left hemiparesis and dysarthria occurred suddenly on the fourth day of hospitalization, 11 days after ET. The neurologic deficits progressed to complete hemiplegia within a few hours. Computed tomography of the head showed infarction in the territory of the right middle cerebral artery. Magnetic resonance angiography revealed occlusion of the main trunk of the right middle cerebral artery. Laboratory studies showed leukocytosis with neutrophil predominance and a hypercoagulable state. The pregnancy was terminated because of progressive tachycardia, dyspnea, and increased abdominal girth despite supportive treatment. The neurologic deficits remained stationary at the time of discharge. This case emphasizes that the recent advent of ovulation induction and assisted reproductive techniques is a newly recognized cause of devastating cerebral infarction in otherwise healthy women.

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.

A previously healthy man aged 18 years suddenly developed a severe headache, followed by nausea, vomiting, fever. During the following weeks a left-sided hemiparesis developed. CT of the brain revealed a pansinusitis and a frontal epidural empyema. A few days after surgical drainage his condition deteriorated and subsequent CT showed a right-sided subdural empyema. This was surgically evacuated and followed by long-term high-dose intravenous antibiotic therapy. The patient made a complete recovery. A sudden severe headache can be caused by an intracranial infection and intracranial pus collections can occur in the subdural as well as in the epidural space. Epidural empyema is a limited disease with relatively mild symptoms and a favourable prognosis, whereas subdural empyema may rapidly spread and cause severe disease with a poor prognosis. Quick antibiotic treatment and surgical drainage are required.

We reported a rare case, which was successfully treated by PTA, of right common carotid artery dissection propagated from acute aortic dissection (AAD) type A. A 45-year-old male with a past history of hypertension and an artificial graft replacement of the abdominal aorta due to AAD type B, 7 years ago, was brought into our hospital by ambulance 30 minutes after an attack of fainting and left hemiparesis. On admission, the patient complained not of chest pain or left hemiparesis, but nausea. At that time his consciousness level was JCS 1. During examinations, he had the same attack twice and his consciousness level deteriorated to JCS 2. Brain MRI showed no abnormality, but cervical MRA did not visualize the right carotid artery and thoracic CT depicted acute aortic dissection including branches of the aorta. Emergent angiography disclosed that the dissecting 99% stenosis of the right common carotid artery had developed from AAD type A with poor collateral blood flow. PTA was carried out 8 times and reduced the residual stenosis to about 50% with shortened circulation time. The patient's consciousness disturbance improved. After the replacement of the whole aortic arch in an artificial graft, the residual stenosis disappeared. The patient recovered without neurological deficit but right frontal silent embolic infarction caused by the artificial graft replacement was detected. AAD is a catastrophic illness and sometimes accompanied by devastating ischemic cerebral disease (ICD) because of propagation of dissecting to extracranial vessels. This is the first report that shows the efficacy of PTA for treatment of ICD associated with AAD.

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.

Homocystinuria presenting as cerebral venous thrombosis is not usual. We report on a 13-year-old boy who was admitted to the hospital due to severe headache, nausea, vomiting and fever (38 degrees C). The patient was Marfan like and presented left hemiparesis and meningeal irritation sings. He was mentally retarded, had severe myopia, and had right lens dislocation one month before. Cranial CT scan was suggestive of cerebral venous infarct. MRI and magnetic resonance angiography showed venous infarcts more prominent in the right thalamic projection with hemorrhagic transformation and multiple foci of cortical (occipital and parietal bilaterally) deep parietal and left capsular bleeding, secondary of thrombosis of the transverse and sigmoid venous sinuses. High levels of homocysteine were detected in the blood and urine. Homocystinuria is an autosomal recessive inborn error of methionine metabolism caused by cystathionine-beta-synthase defect in most cases. We discuss the clinical and radiological findings in this patient, analyzing the pathophysiology of the thrombotic events related to homocystinuria.

A 21-year-old woman experienced severe headache and nausea one hour after taking pills containing 160 mg of phenylpropanolamine for common cold. She had no previous history of drug abuse or hypertension. Physical examination revealed slight left-sided hemiparesis. Her blood pressure was 100/52 mmHg. Subcortical hemorrhage was noted in the right frontal lobe with a cranial computed tomography. On the seventh hospital day, cerebral angiography demonstrated with segmental narrowing of a branch of the right anterior cerebral artery, indicating the presence of focal angitis. This finding disappeared on the 35th hospital day. In the majority of the reported cases of the intracerebal hemorrhage associated with the ingestion of phenylpropanolamine, focal angitis rather than induced hypertension is considered to be a causative factor for hemorrhage. Thus, we would like to emphasize that the administration of phenylpropanolamine should be avoided, even to the patients without hypertention or past history of intracerebral hemorrhage.
