Renal tuberculosis presenting as a mass lesion in a two-year-old girl: Report of a rare case

Genitourinary tuberculosis usually occurs in young adults and the middle-aged and is very uncommon in the paediatric population. it generally presents with haematuria,pyuria,irritative voiding symptoms and flank pain; presentation as a renal mass is highly unusual. we report a two-year-old girl who was referred to the nil ratan sircar medical college,kolkata,india,in june 2014 with abdominal pain. subsequent radiological investigations revealed a left renal hypoechoic mass lesion. a left nephroureterectomy was performed on suspicion of a wilms’ tumour. histopathology indicated an epithelioid granuloma with lymphocytic infiltration,suggestive of a tubercular aetiology. a mantoux tuberculin skin test was positive; however,there was no evidence of tuberculosis detected elsewhere in the body and the source of the infection could not be identified. a diagnosis of renal tuberculosis was made and the child was treated with antitubercular drugs. the patient was asymptomatic at a six-month follow-up. © 2016,sultan qaboos university. all rights reserved.
