Keraunoparalysis: Fleeting Paralysis Following a Lightning Flash

Lightning strikes cause a spectrum of manifestations in the human body. Keraunoparalysis is a neurological condition where immediate but transient weakness occurs following a lightning strike. Herein, we report a case of a 45-year-old male with an acute onset of right-sided hemiparesis after a lightning strike. The patient was investigated for probable causes of paralysis with basic investigations and imaging modalities, which did not reveal any significant findings explaining the symptoms. After eliminating other causes of acute neurological deficit, we suspected it to be a case of keraunoparalysis. The patient was observed closely for further progression of symptoms. The patient was managed conservatively, and analgesics were given to relieve the pain. The symptoms started improving in the first 12 hours, with complete resolution within a week of the impact. This case was reported to increase clinicians' awareness of this benign condition to avoid therapeutic mismanagement. Diagnosing keraunoparalysis is possible only after ruling out the other probable causes of neurological deficits.
