The authors report a case of Rathke cleft cyst presenting with severe hyponatremia. A 33-year-old man suffered sudden severe headaches, visual changes, dizziness, nausea, vomiting, and a metallic taste in his mouth. Initial laboratory values demonstrated severe hyponatremia. Magnetic resonance
BACKGROUND
Spontaneous rupture of a Rathke cleft cyst is very rare, and rapid de novo aneurysm formation associated with pituitary apoplexy is rare.
METHODS
A 66-year-old woman experienced severe left temporal pain. Magnetic resonance imaging showed a Rathke cleft cyst, and transsphenoidal surgery
Rathke cleft cysts are remnants of the Rathke pouch. Most of them are asymptomatic, but sometimes they can grow enough to cause compression of structures within and/or close to the sella, thus eliciting symptoms such as visual disturbance, pituitary defects, and headache. Asymptomatic cysts can
Arachnoid cysts are commonly thought to arise from either congenital defects or trauma. In this article the authors report the spontaneous development of a suprasellar third ventricular arachnoid cyst whose origin was not clearly congenital or traumatic. At the age of 4 months, the patient presented
We describe an 18-year-old female who complained of general weakness, nausea, vomiting, headache, and lightheadedness. On physical examination, she was euvolemic without visual or neurological deficits. The striking biochemical abnormality was hyponatremia (125 mmol/l). This hyponatremia met the
Bobble-head doll syndrome (BHDS) is a rare pediatric movement disorder presenting with involuntary 2- to 3-Hz head movements. Common signs and symptoms also found on presentation include macrocephaly, ataxia, developmental delay, optic disc pallor or atrophy, hyperreflexia, tremor, obesity,
Rathke's cleft cysts are sometimes associated with aseptic meningitis or metabolic encephalopathy due to hyponatremia. We treated such a case manifest by lethargy, fever and electroencephalographic abnormalities. A 68-year-old man was admitted to our ward after experiencing general malaise, nausea
Pituitary apoplexy (PA) is a rare and potentially fatal clinical condition presenting acute headache, vomiting, visual impairment, ophthalmoplegia, altered mental state and possible panhypopituitarism. It mostly occurs in patients with haemorrhagic infarction of the pituitary gland due to a
