TRANSCAVAL ENDOSCOPIC ULTRASOUND-GUIDED FINE NEEDLE ASPIRATION FOR A LYMPHOMA DIAGNOSIS

A transvascular EUS-guided puncture facilitated the diagnosis of an inaccessible lesion in the inter-aortocaval region. The use of fine needles, to achieve a stable and perpendicular plane to the vascular axis, seems the recommended measures to perform a transvascular puncture. A 77-year-old patient with constitutional syndrome, fever and detection by imaging of a solid, hypercaptant retroperitoneal lesion compromising the aorta and inferior cava vein. (I) First, a EUS-guided transduodenal FNA (22G) of a periaortic lesion, was insufficient for diagnosis. Finally, a transcaval EUS-guided FNA of an adenopathy using 25G needle (slow-pull technique) was successfully perfomed. ROSE confirmed atypical lymphocytes.
