A Rare Case of Lumbar Region Diastematomyelia in a 25-year-old Woman With Lower Back Pain.

Diastematomyelia is an infrequent congenital anomaly that anatomically presents with a longitudinal division of the spinal cord at the level of one or several sections. It is generally diagnosed and treated in children. We present a 25-year-old female patient who has entered the Neurosurgery clinic after a traumatic experience with severe low back pain evaluated with 7 points on the visual analog scale (VAS). Magnetic resonance imaging (MRI) of the lumbar area discovered evidence for diastematomyelia type 1 at levels L3-L5 with deformations in L4 and L5 vertebrae and mild scoliosis. Because of the lack of neurological deficiency, the patient's treatment was conservative and included a 10-day intake of nonsteroid anti-inflammatory drugs (NSAIDs) in combination with myorelaxant and physiotherapy. On the 15th day, the patient was evaluated with 2 points on VAS. Neurological follow-up examinations were conducted on the third and the sixth month and the patient was evaluated with VAS 1, which proves that conservative treatment is successful for diastematomyelia in adults without neurological deficiency.
