Abdominal tuberculosis is a grave infection resulting in high morbidity and mortality if left untreated. The diagnostic approach to this disease has drastically changed since arrival of modern CT scan. Role of MRI for the diagnosis is yet to be fully established and is in early stages. In future, patient profile, diagnostic information required, merits and demerits of both the technologies will determine their utility. The purpose of this article is to review CT and MR imaging findings in abdominal tuberculosis.

Horseshoe lung, usually associated with pulmonary venolobar syndrome, is a rare congenital anomaly involving the fusion of the postero-basal segments of the right and left lungs across the midline. The fused segment or the isthmus lies posterior to the pericardium and anterior to the aorta. The associated pulmonary venolobar syndrome involves anomalous systemic arterial supply and anomlaous systemic venous drainage of the right lung. With the advent of MDCT imaging, we can diagnose this rare condition as well all its associated anomalies non-invasively. Volume-rendered techniques greatly simplify the complex anatomy and provide easy understanding of the same.
