Axial (A) and sagital (B) images of an abdomen computed tomography illustrates multiple diverticula in the sigmoid colon. One showed thickened walls (arrows) with adjacent fat stranding, findings consistent with acute diverticulitis

The patient was submitted to a contrast-enhanced CT of the abdomen, with findings consistent with non-complicated acute diverticulitis in the sigmoid colon ( Figure 3 ).
Axial (A) and coronal (B) images of a chest computed tomography illustrate multiple and bilateral ground glass opacities, septal thickening and reticulation, findings consistent with COVID-19

A chest CT was performed on March 23, 2020, and showed typical findings for COVID-19 ( Figure 4 ).
Axial images (A and B) of the lung basis in an abdomen computed tomography show subtle ground glass opacities with some septal thickening, which possibly represented incipient COVID-19 changes (arrows)

A retrospective analysis of the lung basis on the abdomen CT on March 18, 2020 revealed discrete ground-glass opacities with areas of thin reticulation and septal thickening on the periphery of the medium lobe and on the posterior basal segments of both lungs, findings that possibly were related to incipient COVID-19 changes ( Figure 5 ).

Axial (A) and coronal (B) images of a non-enhanced abdomen computed tomography show thickened walls in the cecum and terminal ileum, with fat stranding (arrows), consistent with enterocolitis

An abdominal CT with no contrast enhancement was requested, which revealed a thickened ascending colon and distal ileum, associated with adjacent fat stranding, findings that suggested enterocolitis ( Figure 6 ).
Axial (A) and sagital (B) images of the lung basis in an abdomen computed tomography show ground-glass opacities with septal thickening and fine reticulation, typical COVID-19 pulmonary findings

In the same exam, on the pulmonary basis, areas of peripheral ground-glass opacities were observed on both lungs, especially on the left, and pleural effusion on the right lung ( Figure 7 ).
