Abstract
In the modern era, radiological and pathological investigations have made the diagnosis of gynecological diseases easier and reliable. However, in rare instances, very large masses may mask the actual diagnosis and are mimicked by some other abdomino-gynecological diseases especially in pregnancy, where the diagnosis and treatment options both become very difficult. In case under discussion a very large uterine leiomyosarcoma, presented with second trimester pregnancy. Multidisciplinary team approach and anticipation of such differentials could be helpful in such scenarios.
