TY - EJOU AU - Marien, Tracy AU - Zhou, Ming AU - Brucker, Benjamin TI - Benign multicystic mesothelioma masquerading as a urachal cyst T2 - Canadian Journal of Urology PY - 2014 VL - 21 IS - 6 SN - 1488-5581 AB - Benign multicystic mesothelioma (BMM) is a benign intra-abdominal lesion that generally occurs in women in their reproductive years. A urachal cyst occurs when the epithelial-lined urachal canal fails to completely obliterate. We report a case of a 38-year-old female presenting with abdominal pain found to have a lesion highly suspicious for a urachal cyst. On pathologic evaluation the lesion was identified as a BMM. This is the first report of BMM presenting as a lesion suspected to be a urachal cyst. KW - benign multicystic mesothelioma KW - urachal cyst KW - urachus DO -
