A 32-year-old male presented with progressive pure amnesia caused by astrocytoma invading the bilateral medial temporal lobes. Methionine positron emission tomography demonstrated the extent of tumor invasion well. His memory impairment was partially improved by treatment for the astrocytoma. Lesion of the bilateral hippocampus causes memory impairment, but pure memory loss without other associ...

The risk of stroke and management of coiling of the cervical internal carotid artery in the absence of an atherosclerotic carotid bulb lesion is unclear. We report a case of an otherwise healthy 39-year-old woman who developed bilateral sequential strokes associated with bilateral coiled internal carotid arteries. We discuss the risk of stroke and management of coiled carotid arteries as they r...

We report a case of 48-year old woman who presented with dementia, progressive mental decline, personality change, paresis of the right lower extremity, and gait ataxia. Magnetic resonance imaging (MRI) T1-weighted image revealed bilateral thalamic swelling with homogenous low signal intensity and mild contrast enhancement with gadolinium. The T2weighted image showed high intensity lesions in t...

CASE REPORT To describe a case of combined bilateral cranial nerve palsy of traumatic origin. To determine the lesions that produce the symptoms is useful to define the final prognosis and the best treatment. DISCUSSION We report the case of a patient who developed a bilateral sixth nerve and left third nerve palsy after head trauma. The underlying lesion was a diffuse axonal injury. After an...

The presence of bilateral large effusions in sarcoidosis is unu­ sual. The reported prevalence of pleural involvement in sar­ coidosis varies from 0 to 5% [1] with unilateral, small effusions usually. Clinically significant bilateral effusions in sarcoidosis are rare. There are few other reports of sarcoidosis presenting with bilateral pleural effusions but the quantity of fluid was small and c...

We made simultaneous bilateral recordings of unit activity in the n. 9 ventroposterior lateralis (VPL) in intact rats, and after acute and chronic left thoracic 10 hemisection. We observed an immediate bilateral decline in multireceptive units, 11 reflecting a loss of nociceptive input on the lesion side and a loss of low threshold 12 inputs contralaterally. Unit properties were restored to nor...

There are limited case reports of structural lesions causing Korsakoff syndrome. This report describes acute Korsakoff syndrome following localized, bilateral infarction of the mammillothalamic tracts (MTTs). Axial T2-weighted imaging revealed the lesions at the lateral wall level of the third ventricle and diffusion-weighted imaging confirmed that the left lesion was new and the right old. Kor...

A patient with mitochondrial myopathy is described. Examination of his fundus revealed bilateral vitelliform degeneration of the maculae. This lesion is a focal abnormality of the retinal pigment epithelium and may be a manifestation of the underlying mitochondrial disease.

CASE REPORT A 37-year-old patient with a painless genital lesion for 60 days. Long-term partner for many years, he reported casual unprotected sexual intercourse about four months ago. On dermatological examination, elongated, raised, shiny lesion with a cartilaginous consistency, partially surrounding sulcus was observed (Figure 1). Also detected a bilateral, firm and mobile inguinal lymphaden...

PATIENT A patient with subarachnoid hemorrhage developed severe, diffuse, distal bilateral middle cerebral artery vasospasm with resultant cortical laminar necrosis and transient cluster breathing. Intervention Magn...
