A rare case of patent Urachus with calculus with Omphalolith

Patent urachus is a well-known pathological and clinical entity presenting usually in infancy or in the elderly (Burns et al., 2004). Urachal affections are rare. Their variable ways of presentation may represent a diagnostic challenge. Urachal sinuses are a rare type of these abnormalities (Nix et al., 1964). Omphalolith (Umbolith) is uncommon under normal circumstances. However in a deeply retracted umbilicus in an obese individual, accumulation of sebum and keratin may lead to the formation of a stone (Russel et al., 2004). This calculus may remain undiagnosed for many years until revealed by secondary infection or ulceration. We report a case of 45 year old male with urachal sinus as umbilical discharge. The diagnosis was suspected clinically and confirmed with ultrasonography and computed tomography scan. An initial broad spectrum antibiotic therapy followed by complete excision of the sinus and fibrous tract done. The postoperative course was uneventful. Histological examination did not reveal any sign of malignancy. The post operative period was uneventful and discharged on sixth post operative period. it is being presented for its rarity.
