A Case Report of Grisel's Syndrome Complicating the Postoperative Course of Craniotomy for a Massive Cystic Brain Lesion.

This report presents the case of a seven-year-old child diagnosed with Grisel's syndrome following a craniotomy for a cystic brain lesion. The patient initially presented with persistent, progressively worsening headaches that coincided with neurological symptoms. Imaging revealed a massive cystic lesion causing a significant compression and midline shift. Following craniotomy and insertion of a left frontal Ommaya reservoir, the patient developed Grisel's syndrome, characterized by painful neck muscle spasms and rotation to the right. Management included the application of halo traction to ensure rigid cervical spine immobilization, closed reduction, and subsequent transition to a halo vest to maintain alignment and facilitate gradual recovery.
