Vertebral cryptococcosis simulating tuberculosis

Infection with the fungus Cryptococcus neoformans is seen predominantly in two forms: (a) pulmonary and (b) cerebromeningeal. Skeletal cryptococcosis is uncommon. There have been only occasional case reports of thoracic vertebral cryptococcosis presenting as cord compression. A young female had cervical lymphadenopathy diagnosed as tuberculosis by fine needle aspiration cytology (FNAC) and was on antitubercular therapy (ATT) for 5 months. She developed rapidly progressive paraparesis and imaging demonstrated a destructive vertebral body lesion involving T2-3 with a paraspinal abscess producing cord compression. A costotransversectomy with excision of the diseased bone and bone grafting was done. Histopathological examination revealed cryptococcosis. The patient was put on antifungal medication, but expired 2 weeks after surgery. Radiological, magnetic resonance imaging and surgical finding of vertebral cryptococcosis can mimic tuberculosis. The definite diagnosis of cryptococcosis depends upon microscopic identification of the organism. A high index of suspicion leading to early surgical confirmation and institution of anti fungal therapy is necessary to reduce the mortality and morbidity.
