Neurologic complications associated with inferior petrosal sinus sampling for adrenocorticotropic hormone in the diagnosis of Cushing syndrome are rare. Previously reported complications include brain stem infarction and pontine hemorrhage. We report a case of venous subarachnoid hemorrhage with subsequent acute obstructive hydrocephalus occurring during inferior petrosal sinus sampling for Cus...

BACKGROUND AND PURPOSE This case report documents a rare opportunity to observe the motor function of an individual for nearly 6 months following a primary pontine hemorrhage in the medial pontine tegmentum of the brain stem. The purpose of this report is to illustrate how knowledge of the location of the hemorrhage, in conjunction with knowledge of brain-stem structure-function relationships, ...

BACKGROUND AND PURPOSE Pure sensory stroke (PSS) usually is caused by a lacunar infarct; reports of PSS caused by cerebral hemorrhage have been rare. We correlated clinical and neuroradiologic findings in patients with PSS caused by cerebral hemorrhage. METHODS We retrospectively studied seven patients with appropriate clinical findings and lesions revealed by X-ray CT and MR imaging (five me...

Introduction: Vertebrobasilar dolichoectasia (VBD) is an arterial disease characterized by dilatation, elongation, and tortuosity of the vertebral basilar arteries. VBD can generate intracranial hemorrhage, compression brainstem, ischemic stroke as most common presentation. Millard-Gubler syndrome (MGS) a pontine-crossed affecting pons at level facial nerve nucleus. We present unusual case post...

Hypertrophic olivary degeneration is a rare kind of trans-synaptic degeneration that occurs after lesions of the dentatorubro-olivary pathway. The lesions, commonly unilateral, may result from hemorrhage due to vascular malformation, trauma, surgical intervention or hypertension, tumor, or ischemia. Bilateral cases are extremely rare. This condition is classically associated with development of...
