Chronic cough as the presenting symptom of hydrocephalus

Chronic cough is defined as a daily cough lasting for more than eight weeks. We report an unusual case of chronic cough as the primary manifestation of obstructive hydrocephalus. Chronic cough in our case was determined to be of neurogenic origin only after exhaustive investigations failed to reveal a systemic cause, and, in particular, after a positive response to treatment of the hydrocephalus was observed. To the best of our knowledge, this is the first report of hydrocephalus presenting as chronic cough. We believe this case will remind physicians of the importance of considering neurological disease as a cause of chronic cough after common causes are excluded.
