ABSTRACT
Neuromyelitis optica spectrum disorder (NMOSD) may present with area postrema syndrome, which is characterized by intractable vomiting and hiccups. Hyponatremia is common in NMOSD and is mostly associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In contrast to SIADH, cerebral salt wasting syndrome (CSWS) causes hyponatremia, which is associated with severe natriuresis and extracellular volume depletion in patients with cerebral disease. To our knowledge, hyponatremia associated with CSWS has not been reported in a patient with NMOSD. Here, we describe a NMOSD presenting with hyponatremia, which may be caused by CSWS following area postrema syndrome.

Mucormycosis is a rare opportunistic infection caused by fungi of the order Mucorales that typically occurs in patients with diabetes or immunocompromised state. Rhino-orbital-cerebral mucormycosis is the most common type, often has a life-threatening outcome. Mucormycosis has specific vascular tropism complicating mucorthrombosis or mycotic aneurysm. We report a diabetic patient presenting with ophthalmoplegia, orbital necrosis, and contralateral hemiparesis, who suddenly progressed to coma and died of subarachnoid hemorrhage due to the rupture of mycotic aneurysm in distal internal carotid artery.
