Dear Editor, Since the original description of ipsilateral occipital-lobe infarction from a tentorial herniation in 1920,1 pathologic and neuroradiologic studies have suggested posterior cerebral artery (PCA) impingement against the leading edge of the tentorial incisura as the underlying mechanism. However, the rare cases of isolated contralateral PCA infarction have not been explained. The ca...

Transient visual disturbance following cardiac catheterization has been regarded as a benign and transient complication. We describe two cases of computed-tomography-documented occipital infarction after cardiac catheterization that emphasize a complication more serious than previously thought.

BACKGROUND Acute renal infarction is a rare entity with varied misleading manifestations resulting in diagnostic delay, misdiagnosis, and treatment leading to renal damage. CASE PRESENTATION We report the case of a 28-year-old Dalit Nepalese man who presented with sudden onset occipital headache and later developed severe left flank pain. He was diagnosed with posterior cerebral infarction wi...

Spontaneous Intracranial Hypotension (SIH) is usually due to cerebrospinal fluid (CSF) leak, resulting in loss of CSF volume. Posterior reversible encephalopathy syndrome (PRES) the inability posterior circulation brain autoregulate response significant variation blood pressure. Altered perfusion with associated blood-brain barrier disruption may lead vasogenic edema, without infarction, common...

Neurological deficits can occur following snake bite. It is usually due to intracerebral haemorrhage or subarachnoid bleed as a result of depletion of clotting factors. A healthy 14-years-old male developed bilateral ptosis and altered sensorium within 3 hours of snake bite. CT Brain revealed bilateral cerebellar and right occipital infarction with mass effect. Clotting time and bleeding time w...

RATIONALE Occlusive cerebrovascular disease is the most common cause of homonymous hemianopia (HH) with macular sparing. PATIENT CONCERNS A 61-year-old man came to our ophthalmology clinic complaining of right-side hemianopia. Ophthalmic examination, visual field (VF) examination, and brain magnetic resonance imaging (MRI) were performed. DIAGNOSES He had right HH without macular sparing on...

Giant fusiform basilar aneurysms (dolicho-ectatic basilar anomalies) are rare and have not previously been reported to cause embolic infarction in territory distal to the aneurysm. They most commonly present as posterior fossa mass lesions with brainstem compression and cranial neuropathies. Originally considered atherosclerotic in etiology, recent authors feel that they may represent a unique ...
