At the level of the middle abdomen, colour Doppler examination indicated the presence of a parenchymatous, vascularised structure. The splenic parenchyma shows millimetric focal, hypo/isoechogenic lesions with blurred margins, not extending beyond the organ profile. The peritoneum appears diffusely hyperechogenic. Minimal layers of anechogenic effusion.

Hyperechogenic liver parenchyma without structural alterations. Distended gallbladder, severe parietal thickening, anechogenic endoluminal contents intermixed with finely corpusculated hyperechogenic material in suspension, not generating posterior shadow cone, also evident at the level of the common bile duct.

Mesenteric lymph nodes severely increased in size, hypoechogenic, with increased sphericity index.

Focal thickening of an intestinal loop, probably of jejunal relevance (7.2 mm), associated with loss of stratigraphic distinction.

Jejunal loop, mesenteric lymph nodes, peritoneal reactivity, layers of anecogenic effusion evidenced in the examined quadrants.

The ultrasound picture is compatible with an infiltrative process, probably of neoplastic origin (DD: Lymphoma, Carcinoma). Recommended cytological test for diagnostic purposes.
