Transient Obstructive Hydrocephalus in Patients with Intracerebral Hemorrhage: Report of Two Cases.

Obstructive hydrocephalus is a relatively common complication of intraventricular hemorrhage resulting in high morbidity and mortality. We report two cases of transient obstructive hydrocephalus caused by obstruction of mesencephalic duct in patients that presented with altered consciousness which resolved spontaneously in a few hours. In very rare cases, obstructive hydrocephalus due to intraventricular hemorrhage may be transient and does not need neurosurgical or invasive procedures for lowering raised intracranial pressure, which otherwise are currently preferred treatment options.

[Central sleep apnea (Ondine's curse syndrome) in medullary infarction].

Ondine's curse syndrome primarily refers to cases with congenital central alveolar hypoventilation, but the term can also be used for acquired cases and implies central sleep apnea that occurs as a manifestation or complication of focal lesion in the area of the dorsolateral segment of medulla oblongata. It occurs rarely, but can lead to fatal outcome. Based on our own case report, the aim of this article is to review its clinical symptoms, and appropriate diagnostic and therapeutic procedures.
