CASE REPORT 3D CT Evaluation of Common Crus Aplasia
نویسنده
چکیده
Most of the patients who present with congenital sensorineural hearing loss (SNHL) do not demonstrate an imaging abnormality. Only 39% of patients with congenital SNHL have a documented imaging abnormality, with large vestibular aqueduct syndrome being the most common of the congenital anomalies to be identified on imaging. Congenital anomalies of the semicircular canals can result in SNHL. Dysplasia of the lateral semicircular canal has been reported to be the second most common cause after large vestibular aqueduct syndrome to be so associated. Common crus aplasia is an uncommon congenital anomaly. We report the case of a patient with common crus aplasia and review the underlying pathogenesis.

Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus–related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a comple...
متن کاملAbsence of the common crus in Goldenhar syndrome.
We describe an unusual labyrinthine malformation in a case of Goldenhar syndrome studied with CT and steady-state MR imaging. A single posterosuperior semicircular canal was found with no common crus formation. The malformation could not be attributed to any embryologic development. Nosologic considerations are discussed.
