[When a patient falls (asleep) and can't get up: conversion disorder - paraplegia following general anesthesia]

This case report describes the rare occurrence of paraplegia caused by conversion disorder in a woman who received general anesthesia for breast surgery.

A 46-year-old healthy woman received general anesthesia for excision of a left breast fibroepithelial lesion. In the post-anesthesia care unit, she reported bilateral loss of both sensation and motor function below the knees. Physical signs and symptoms did not correlate with any anatomical or neurological patterns; imaging revealed no abnormalities. Psychiatric consultation was performed wherein familial stressor circumstances were identified, leading to diagnosis and management of conversion disorder.

Conversion disorder is characterized by alteration of physical function due to expression of an underlying psychological ailment. Its diagnosis requires thorough evaluation including appropriate workup to exclude organic causes. The meshing together of anesthesiology and psychiatry - as demonstrated by this case report - offers an opportunity to highlight important information pertaining to the definition, diagnosis, and management of conversion disorder as it may be encountered in the postanesthesia recovery period.
