Neurogenic pulmonary edema associated with a colloid cyst in the third ventricle. Case report

Neurogenic pulmonary edema (NPE) is usually the result of head trauma. The authors describe the case of a 13-year-old girl, in whom NPE was associated with a colloid cyst of the third ventricle causing acute hydrocephalus. The mechanisms involved in the development of NPE are briefly discussed. The possible role of the colloid cyst in the distortion of the anatomical relationships in the vicinity of the hypothalamic nuclei is considered.
