UNASSIGNED: @entity1201 , or @entity1201 , is a chronic @entity166 with many manifestations. Though still a major health concern and leading cause of @entity1897 in the developing world, it is rare in the United States, with only about 150 cases reported each year. Nevertheless, it is imperative that neurosurgeons consider it in the differential diagnosis of @entity16 . The causative organism is @entity4430 , which infects and damages Schwann cells in the peripheral nervous system, leading first to sensory and then to motor deficits. A rare presentation of @entity1201 is pure @entity527 . It is characterized by nerve involvement without the characteristic cutaneous stigmata. The authors of this report describe a case of pure @entity527 presenting as @entity16 with corresponding radiographic, electrodiagnostic, and histopathological data. This 11-year-old, otherwise healthy male presented with progressive @entity425 and @entity1183 with no cutaneous abnormalities. Physical examination and electrodiagnostic testing revealed findings consistent with a severe @entity16 at the elbow. Magnetic resonance imaging revealed diffuse thickening and enhancement of the ulnar nerve and narrowing at the cubital tunnel. The @entity1 underwent ulnar nerve decompression with biopsy. Pathology revealed acid-fast organisms within the nerve, which was pathognomonic for @entity1201 . He was started on antibiotic therapy, and on follow-up he had improved strength and sensation in the ulnar nerve distribution. Pure @entity527 , though rare in the United States, should be considered in the differential diagnosis of those presenting with @entity1897 and a history of travel to @entity1201 . The long incubation period of @entity4430 , the ability of @entity1201 to mimic other conditions, and the low sensitivity of serological tests make clinical, electrodiagnostic, and radiographic evaluation necessary for diagnosis. Prompt diagnosis and treatment is imperative to prevent permanent @entity16 .
