Psoas abscess secondary to tuberculous lymphadenopathy: case report

Tuberculous psoas abscesses, a well-known sequel of tuberculous spondylitis , very rarely develop without concomitant spinal involvement. We report a u nique case where a psoas abscess was secondary to retroperitoneal tuberculo us lymphadenopathy in a 13-year-old boy who had no demonstrable findings of spinal tuberculosis. Computed tomography showed an obvious communication b etween the necrotic and calcified retroperitoneal lymph node and the psoas abscess. To the best of our knowledge, fistulization of tuberculous lymph n odes into the psoas sheath has not been reported in the English-language li terature.
