Filarial Epididymitis: A Diagnostic Challenge in Pediatric Acute Scrotum.

Genital lymphatic filariasis (LF) is a condition that can present both acutely and chronically, complicating its diagnosis due to nonspecific symptoms. This case report describes an 11-year-old boy who presented with symptoms of acute scrotum. Initial Doppler ultrasound suggested acute epididymo-orchitis; however, despite conservative management, the symptoms persisted, prompting surgical exploration. The surgery revealed an edematous epididymis with a cystic lesion, leading to a diagnosis of filarial epididymitis. This case highlights the diagnostic challenges associated with genital filariasis and underscores the importance of considering it in the differential diagnosis of scrotal swelling, especially in endemic regions. Surgical intervention not only confirms the diagnosis but also alleviates symptoms and helps prevent future complications such as infertility.
