A Rare Case of Situs Inversus Partialis With Levocardia in a 73-Year-Old Patient.

Situs inversus partialis (SIP) is an extremely rare congenital disorder in which most of the visceral organs are located on the opposite side of their usual anatomical locations. The condition is usually associated with levocardia, in which the apex of the heart is directed toward the left side. In our case study, a female patient with a history of dysphagia and weight loss presented to the outpatient clinic under the urgent two-week wait pathway. She underwent a CT scan of the thorax, abdomen, and pelvis, which revealed that she has SIP in which some of the abdominal organs are reversed and others are in their normal anatomical locations. The patient was diagnosed with esophageal carcinoma. However, because of her rare condition, it was challenging to insert a nasogastric tube into her reversed stomach and to explore other feeding options, e.g., jejunostomy. This report discusses a rare case of SIP, incidentally discovered in a patient with suspected esophageal malignancy, and its associated surgical challenges in her management.
