Figures

Figure 1
Fig. 1
Images from portal venous phase CT scan of the abdomen. A: Axial CT image highlighting the jejunal overdistension (caliber of ∼ 54 mm; normal range < 30 mm), with associated signs of intramural bowel gas (arrow) as per pneumatosis intestinalis. Non signs of pneumoperitoneum identified. B: Paracoronal CT image nicely demonstrating the differences between the hypoenhanced/unenhanced (circle) and the regularly enhanced (arrows) small bowel loops: these findings are clearly suggestive of small bowel ischemia. C: Paracoronal CT image showing the longitudinal extension of a thromboembolic defect into the lumen of the inferior vena cava (arrow). D: Paracoronal CT reconstruction along the vascular axis of the superior mesenteric vein which is largely occupied by an extensive thromboembolic defect (arrow); the superior mesenteric artery and its main branches were patent (not shown).

Fig. 2
Histological section of mesentery showing recent occlusive thrombosis of a medium size vein (left) and of a muscular artery (right); mixed inflammatory infiltrate is attacking the endothelium of both vessels (Hematoxylin and eosin, 400X).

Fig. 3
The RNAscope probe detected positive staining for COVID-19 viral RNA (brown dots) in the intestinal mucosa, giving rise the chance to estimate the viral load in cells within the morphological context.
