An incidental finding of splenic vein aneurysm in 59-year-old woman with systemic lupus erythematosus

This case report discusses a rare presentation of a splenic vein aneurysm (SVA) incidentally discovered in a 59-year-old female patient with a history of systemic lupus erythematosus (SLE), interstitial lung disease (ILD), and chronic liver disease (CLD). The patient presented with symptoms of cough and breathlessness, leading to an abdominal ultrasound, which revealed a cystic lesion in the distal pancreas with a venous waveform. Further evaluation through contrast-enhanced computed tomography (CECT) confirmed the diagnosis of SVA, showing a saccular outpouching from the splenic vein without thrombosis or extravasation. Given the patient’s asymptomatic status, conservative management and follow-up were advised. SVA is an uncommon entity with potential complications, including thrombosis and rupture. This report adds to the limited literature on SVA, particularly in patients with connective tissue disorders like SLE and conditions of portal hypertension. It underscores the need for further research to establish clearer guidelines for the management and treatment of such aneurysms.
