Abstract
We present a case of a 25-year-old woman with isolated aplasia of the lateral semicircular canal (LSCC), a rare congenital malformation that results in the absence or underdevelopment of the LSCC. The patient had vertigo, left-sided tinnitus, and persistent chronic headaches but no hearing loss. High-resolution computed tomography (CT) and magnetic resonance imaging (MRI) were used to detect the malformation and associated vasculo-neural conflict. The aplasia of the LSCC was the only abnormality observed. The article explains the embryology of inner ear development and associated anomalies. CT and MRI were found to be effective imaging techniques for detecting ear malformations. The article also explains the importance of proper diagnosis and assessment of hearing loss for patients with this malformation.
