Paradoxical Hyperreflexia in a Patient With Classic Guillain-Barré Syndrome.

Background: Guillain-Barré syndrome (GBS) is a rare entity with characteristic features, including progressive ascending paralysis. Patients typically present with progressive symmetrical weakness with areflexia in bilateral lower extremities, which can be confounded by psychiatric comorbidities. This case is unusual in that the patient had paradoxical hyperreflexia and normal CSF protein levels during her initial presentation, later confirmed to be GBS.

A 44-Year-Old Male With Cerebral Venous Sinus Thrombosis.

Cerebral venous sinus thrombosis (CVST) is a rare condition that can result in severe neurological complications when left untreated. Disease pathology results from thrombus development within the superficial cortical veins or the dural sinuses. Thrombosis impedes cerebral drainage leading to venous congestion and consequent increase in cerebral pressure, parenchymal damage, and blood-brain barrier disruption.

Incidental Moyamoya Disease in an Elderly Patient Presenting With Acute Ischemic Pontine Stroke.

Moyamoya disease (MMD) is a rare occlusive cerebrovascular disease that is characterized by progressive stenosis of the terminal portion of the internal carotid artery and its main branches with compensatory development of dilated and fragile collateral vasculature at the base of the brain. MMD has a bimodal age distribution commonly affecting children and adults, whereas onset in the elderly population is a rare occurrence. Here, we present a case of a 78-year-old patient of Indonesian descent who was incidentally found to have moyamoya arteriopathy after presenting with acute ischemic stroke in the left pons.
