Situs Inversus Totalis - A Case Report

SITUS INVERSUS TOTALIS is a congenital positional anomaly characterized by transposition of abdominal viscera associated with a right sided heart (Dextrocardia) .It was Mathew Baillie who first described situs inversus totalis in early twentieth century. A transposed thoracic and abdominal organ is a mirror image of the normal anatomy when examined or visualized by tests such as x-ray filming. The term situs inversus is a short form of the Latin meaning inverted position of the internal organs. Generally individuals with situs inversus totalis are asymptomatic and have a normal life expectancy. Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for an unrelated condition. The reversal of the organs may lead to some confusion as many signs and symptoms will be on the reverse side. A 27 years old male patient reported to the Department of Nephrology with the c/o left sided flank pain since 1 week. The Chest X-ray, Ultrasonography, CT scan and MRI were done and he was diagnosed as SITUS INVERSUS TOTALIS. The anatomic, pathologic, embryologic and etiology of complete Situs inversus and related abnormalities are presented in this case with special emphasis to genetic correlation.
