Bidaki Reza, Amin Masoud

Abstract


Objective: This case report highlights arachnoid cyst, a rare benign space-occupying lesions (SOL) formed by an arachnoid membrane containing cerebrospinal fluid (CSF) which in most cases, are identified by accident. Conversion disorder is characterized as a deficit or distortion in neurological functioning, or symptoms suggesting a general medical condition that is not referable to an organic lesion. Methods: We report a case of a 24 year old woman who came to a psychiatrist with history of suicide attempt. She had a history of failed marriage but no history of substance abuse. She had a history of dizziness, light-headedness, blurred vision, seizure and headache for a while. Seizure was identified to be pseudo seizures in further assessments. Results: Diagnosis of Conversion Disorder with Adjustment Disorder was revealed. In Barin Computerized Tomography (CT) scan there was an extra axial cystic lesion with the height, frontooccipital and lateral size of approximately 6.4 cm by 4 cm by 2.5 cm respectively in the left anterior middle fossa and Sylvian fissure. Based on patient's history, the arachnoid cyst and its symptoms may have a synergistic effect on patient's symptoms of conversion disorder. Conclusion: This case reflects the importance of ruling out medical problems in patients with psychiatric symptoms. ASEAN Journal of Psychiatry, Vol. 13 (1): January - June 2012: XX XX.
