{Abstract}: Cruveilhier-Baumgarten syndrome presents a rare manifestation of portal hypertension characterized by a portosystemic shunt through a dilated paraumbilical vein, typically accompanied by classical signs such as caput medusae and a venous hum. We report a compelling case of a 41-year-old male presenting with portal hypertension, exhibiting clinical and radiological features of Cruveilhier-Baumgarten syndrome but notably lacking the characteristic venous hum. Clinical examination revealed moderate splenomegaly with prominent dilated veins and venous thrill but no caput medusae. Laboratory investigations indicated thrombocytopenia and esophageal varices on upper GI endoscopy. Imaging studies confirmed portal hypertension with findings consistent with Cruveilhier-Baumgarten syndrome, including a dilated paraumbilical vein and splenic artery aneurysms, along with the unexpected absence of a venous hum. Despite the classical radiological features, our patient did not present with hematemesis, possibly attributed to the presence of paraumbilical veins. This case highlights the diagnostic challenges and atypical presentations of Cruveilhier-Baumgarten syndrome, emphasizing the importance of comprehensive clinical evaluation and imaging modalities in its diagnosis and management. Management strategies primarily focus on addressing portal hypertension and underlying liver disease. This case underscores the need for further research to elucidate the varied clinical presentations and pathophysiology of Cruveilhier-Baumgarten syndrome variants, enhancing our understanding and management of this rare entity.
