OCD Symptoms and Capgras Syndrome in a 13-Year-Old Girl Following Right-Sided Brain Surgery.

This case report documents a rare presentation of obsessive-compulsive-like symptoms co-occurring with Capgras syndrome following surgical resection of a right-sided frontal lobe pleomorphic xanthoastrocytoma in a 13-year-old girl. The patient initially presented with headache and intractable vomiting, leading to the discovery of a right-sided frontal lobe tumor. Postoperatively, the patient exhibited cognitive and behavioral changes manifesting as misidentification beliefs regarding the identities of loved ones and associated distressing thoughts. Comprehensive psychiatric evaluation using validated assessment tools confirmed these presentations. This report contributes to understanding the complex interplay between neurological, psychiatric, and cognitive factors in the development of these rare postsurgical neuropsychiatric complications following frontal lobe tumor resection.
