We report a case treated successfully by emergency carotid endarterectomy (CEA) for progressing stroke resulting from pseudo-occlusion of the internal carotid artery (ICA). A 67-year-old male was admitted to our hospital with dysarthria. Neurological examination on admission revealed mild left-sided motor weakness and dysarthria. Computed tomography (CT) showed cerebral infarction in the territory of the perforating artery of right middle cerebral artery (MCA). Magnetic resonance (MR) imaging indicated similar findings and cervical MR angiography revealed occlusion of right cervical ICA. Cerebral conventional angiography and CT angiography revealed pseudo-occlusion of the right ICA. ECD-single photon emission tomography (SPECT) indicated low perfusion in the territory of the right ICA. Conservative therapy was performed using free radical scavengers and antiplatelet drugs, but neurological signs deteriorated. Revascularization using CEA was therefore performed. After surgery, the patient was restless with neurological abnormalities, and trans-cranial Doppler (TCD), INVOS-3100 and MRA revealed hyperperfusion. Strict control of blood pressure under propofol anesthesia allowed effective management of hyperperfusion syndrome. After a 1-month follow-up period, the patient was discharged with only mild left hemiparesis.

A 47-year-old man was admitted to the hospital because of general convulsion, loss of consciousness and hyperthermia. A diagnosis of acute heat stroke was made clinically and neuroradiologically. As the consciousness level ameliorated, he developed severe abulia and mutism, then cerebellar ataxic syndrome (viz. truncal ataxia, hypermetria, ataxic speech and nystagmus). An MRI (diffusion weighted image; DWI) disclosed abnormal diffuse high signal intensity of the cerebellar cortex with reduced apparent diffusion coefficient (ADC). Two months later after the onset, truncal ataxia and dysarthria significantly improved, while dysmetria of the extremities rather worsened. At that time, the abnormal signal intensity of the cerebellar cortex disappeared, and the cerebellum became atrophic. The cerebellar blood flow was significantly decreased on brain SPECT (99mTc-ECD). The abnormal DWI signal intensity of the cerebellar cortex in the present patient may represent the cytotoxic edema of Purkinje cells resulting from heat stroke-related hyperthermia It is essential to repeat MRI examination for cerebellar pathology and to obtain better insight into sequelae in patients with acute heat stroke. Protirelin tartrate seemed to be valid for improvement of abulia in the present patient. Further study is indicated.
