Colpocephaly in an adult: A rare case report.

Colpocephaly is the disproportionate enlargement of the occipital horns of the lateral ventricles. It is usually diagnosed in the neonatal period or early childhood due to symptom severity. Adult cases of colpocephaly are rarely reported and often incidentally diagnosed. We report a case of colpocephaly with partial agenesis of the corpus callosum in a 30-year-old female with no past medical history. The patient presented after a syncopal episode with associated complaints of dizziness, vomiting, and chronic intermittent headaches. This case highlights the clinical and radiological features of colpocephaly in adults.
