Aplasia of the optic nerve.

Aplasia of the optic nerve is an extraordinarily rare congenital anomaly that affects one or both optic nerves and is associated with the absence of the central retinal vessel and retinal ganglion cells. We report a case of unilateral optic nerve aplasia in a 4-month-old infant who was found to have left microphthalmos on routine postnatal checkup. Family history, antenatal history, and systemic evaluation were unremarkable.

Torsion of a nongravid myomatous uterus: radiological features and literature review.

Torsion of the nongravid uterus is a rare but potentially fatal acute abdominal condition. The non-specific clinical presentation of this condition makes preoperative diagnosis difficult. We describe a patient with uterine torsion in whom the diagnosis was made using contrast-enhanced computed tomography with multiplanar reconstruction.
