Key result
MDCT detects rare mixed-type PAPVR draining to portal vein alongside absent celiac trunk.
Why the study?
Traditional diagnosis of partial anomalous pulmonary venous return via echocardiography or catheter angiography can be limited by inadequate pulmonary vein visualisation or procedural invasiveness, whereas multi-detector computed tomography offers a non-invasive alternative capable of concurrently detecting coexisting vascular anomalies.

This case report highlights the utility of multi-detector computed tomography in non-invasively identifying rare mixed-type partial anomalous pulmonary venous return (draining into both the portal vein and inferior vena cava) and coexisting celiac trunk variations in an adult patient evaluated for pulmonary tuberculosis.

MDCT detection of rare mixed PAPVR with absent celiac trunk raises variant awareness; leaves open prevalence and management data in asymptomatic adults.
Partial anomalous pulmonary venous return (PAPVR) is an uncommon congenital vascular anomaly in which one or more pulmonary veins bypass the left atrium and empty instead into the systemic venous system, producing a left-to-right shunt [1,2]. When the anomaly affects the right lung, drainage may occur into the superior vena cava, right atrium, inferior vena cava, azygos vein, hepatic vein, or portal vein. Diagnosis has traditionally relied on transthoracic or transoesophageal echocardiography and catheter angiography [2,3]. Echocardiography is attractive because it is portable and avoids ionising radiation, but visualisation of the pulmonary veins is not always adequate, and angiography, while accurate, carries the drawbacks of an invasive procedure. Multi-detector computed tomography (MDCT) offers a reliable, non-invasive alternative that can also reveal coexisting vascular anomalies in the same study [5,6,9]. We describe a patient in whom PAPVR and a variant celiac trunk anatomy were both discovered incidentally on MDCT performed for an unrelated pulmonary complaint.

Ali et al. (2026) conducted a case report in Partial anomalous pulmonary venous return (PAPVR), variant celiac trunk anatomy, and pulmonary tuberculosis (n=1). Multi-detector computed tomography (MDCT) was evaluated on Incidental identification of vascular anomalies on MDCT. Multi-detector CT incidentally identified a rare mixed-type partial anomalous pulmonary venous return draining into the portal vein and inferior vena cava alongside an absent celiac trunk in a 40-year-old man.
