We reported a case of bilateral cerebellar hemorrhagic infarction in the distribution of the bilateral superior cerebellar artery. A 58-year-old man suddenly developed dizziness and transient loss of consciousness. The neurological examination revealed left hearing disturbance, left sensory disturbance involving face, dysarthria and bilateral ataxia. This patient was considered to be classic clinical syndrome of right superior cerebellar artery. CT and MRI revealed hemorrhagic infarction corresponding to the full territory of the bilateral superior cerebellar artery. The right posterior cerebral artery was filling through the right posterior communicating artery on the right carotid angiography taken 2 hours after the onset. Bilateral vertebral angiography on the 18th day demonstrated no occlusions in the basilar artery and the bilateral superior cerebellar artery. Hemorrhagic infarction corresponding to the full territory of the bilateral superior cerebellar artery, sparing other territories as the present case, is extremely rare. In this case, cerebral embolism (top of the basilar syndrome) was suggested because of existence of atrial fibrillation and sudden onset.

Clinical features of cerebellar infarction in the territory of the superior cerebellar artery (SCA) were investigated in six male patients, ranging in age from 50 to 69 years. In all patients, there were MR images of infarction located in the area supplied by the SCA. The lesion was on the left-side in 2, right-side in 3 and bilateral (recurrent) in 1 patient. The onset of disease occurred with nausea, vomiting and floating sensation, with no overt brain stem signs other than symptoms of unilateral cerebellar ataxia and dysarthria. Five of the 6 patients had heart disease and cerebral angiography without definite evidence of SCA occlusion, strongly suggesting occlusion of the artery at its periphery due to cardiogenic embolism. A comparison of these 6 patients with those reported previously in Japan suggests that patients with SCA occlusion may be divided into two distinct subgroups: one manifesting diffuse brain stem signs in addition to cerebellar signs, and the other showing cerebellar signs as the only neurologic manifestation. In the former group, comprising the vast majority of patients, SCA occlusion occurred at the origin of the vessel due to a thrombus under a state of hypertension, diabetes mellitus or malignancy, producing signs of brain stem involvement, such as dissociating sensory disturbance and Horner's sign. While in the latter group, which included these 6 patients, paucity of brain stem signs, absence of definite cerebral angiographic evidence of SCA occlusion, and the presence of heart disease were distinguishing clinical features. Cardiogenic cerebral embolism was probably the underlying pathology in many of the cases and the functional prognosis was favorable.

We report a case of pulmonary embolism complicated by paradoxical cerebral embolism in a patient with atrial septal aneurysm and patent foramen ovale. The patient was a 65-year-old obese woman, admitted because of sudden development of right-sided hemiplegia and dysarthria. In the few days before hospitalization she noted painful edema of the right leg and suffered from increasing dyspnea. Echo-Doppler examination of the venous bed confirmed the clinical suspicion of deep vein thrombosis. A pulmonary scan showed multiple perfusion defects in both lungs. On cerebral computerized tomography there were two non-haemorrhagic infarct zones. Contrast transesophageal echocardiography revealed a type II atrial septal aneurysm with right-to-left shunting through a patent foramen ovale. The patient was treated by warfarin, followed by implantation of a caval filter, with a good outcome. Paradoxical embolism may be more common than currently thought. In cases of pulmonary embolism, a careful check for clinical symptoms indicative of a possible paradoxical embolism should be performed and, consequently, a search for possible atrial septal aneurysm or patent foramen ovale.

A 61-year-old man had been treated for malignant fibrous histiocytoma with the pulmonary and the lymph node metastasis in the department of orthopedics in our hospital. He was admitted to our department because of an acute onset of conscious disturbance and non-fluent aphasia. Diffusion-weighted imaging (DWI) showed high signal intensity areas in the bilateral cerebella, thalami and posterior lobes. T2WI did not show any mass effects. Enhanced CT did not reveal any enhanced lesion. He was diagnosed as having cerebral embolism, and his conscious disturbance was improved after medication. Eight weeks later, he presented dysphagia, dysarthria, and ataxia in his extremities. DWI showed multiple lesions of low signal intensity located at the identical place where had showed high signal intensity in the initial DWI. T2WI showed high signal intensity area with mass effect. It was indicated that cerebral metastasis might grow after tumorgenic embolism. This is a rare case that tumor emboluses were developed to the metastatic brain tumors.

A 48-year-old male visited the emergency room suffering from acute dysarthria and right hemiplegia. Brain magnetic resonance imaging (MRI) revealed multiple cerebral infarctions. Echocardiography showed a mass in the left atrium. He was diagnosed with cerebral embolism due to left atrial myxoma. Open heart surgery immediately after the attack is generally considered contraindicated because of such problems as hemorrhagic infarction or brain edema. However, relapse of embolism may make the condition worse and miss the timing of surgery. Eventually, we electively performed excision of the myxoma 20 days after the onset of cerebral infarction. The postoperative course was uneventful. This is a report about a rare case of open heart surgery shortly after the attack. The indication and the appropriate timing of open heart surgery following cerebral embolism were discussed.
