Case in brief

A 46-year-old man developed sudden left-ear fullness and diplacusis monauralis five days after diagnostic lumbar puncture, together with a post-lumbar puncture headache. Audiometry showed elevated bilateral air-conduction thresholds at 250 Hz, greater on the left. In view of the symptoms, audiometric pattern, and timing, the authors presumed secondary endolymphatic hydrops, possibly related to reduced CSF pressure. He was monitored with serial audiometry without active treatment; hearing and auditory symptoms fully recovered 17 days after onset.

What made this case unusual

The presumed hydrops presented with auditory symptoms after lumbar puncture and resolved completely with expectant management, without reported vestibular symptoms.

Diagnostic / clinical pearl

New ear fullness or altered pitch perception after lumbar puncture may accompany low-frequency hearing changes; serial audiometry can document recovery when a pressure-related hydrops mechanism is suspected.
