Unusual manifestations of pediatric neuromyelitis optica.

Neuromyelitis optica is a rare, severe idiopathic disease that predominantly involves optic nerves and spinal cord. Main clinical features of neuromyelitis optica are visual loss, paraparesis or tetraparesis, sensory loss, and sphincter dysfunction. A 13-year-old girl with vision loss and behavioral change was admitted. Her behavioral changes concerned demanding everything, eating cacik (a kind of meal prepared by yogurt) continuously, calling everyone "father," and self-throttling during the last 1 month, and blurred vision started 15 days ago. On cranial magnetic resonance imaging (MRI), multiple lesions were seen. The patient was admitted 40 days later with walking difficulty. There were lesions in the medulla and cervical spinal cord on MRI. Neuromyelitis optica was diagnosed. Vomiting was the beginning complaint in 2 of 5 hospitalizations later. We conclude that neuromyelitis optica may involve atypical symptoms such as behavioral change and vomiting. Atypical presentations may delay diagnosis. Vomiting may be a recurrence messenger.
