Situs anomalies are characterized by the transposition of abdominal and thoracic viscera and vascular organs. It is a rare congenital anomaly, with an incidence varying from between 1/4,000~1/20,000 live births. It can be classified into isolated dextrocardia, situs inversus with levocardia, situs inversus with dextrocardia (so-called situs inversus totalis) and situs ambiguous. We report a case of unexpectedly discovered situs ambiguous. The patient was a 12-yearold girl who had a history of peptic ulcer and gastroesophageal reflux disease and presented with epigastric pain and bloody stool. Her chest X-ray showed gastric gas below the right diaphragm; abdominal computed tomography showed that her stomach, spleen and gallbladder were on the right side of the abdomen; however, her liver was over the midline, mainly on the left side. According to the aforementioned image findings, this patient was diagnosed with situs ambiguous. No other severe diseases such as congenital heart disease or asplenia were found after a series of examinations. She was hospitalized for seven days, and discharged when her clinical symptoms improved significantly. |
