Abstract

Coronavirus disease 2019 (COVID-19) is an acute respiratory syndrome caused by SARS-CoV-2 and is known to cause respiratory and systemic symptoms. A SARS-CoV-2 infection is involved in aneurysm formation, enlargement, and rupture in medium-sized vessels, such as the cerebral and coronary arteries and the aorta. In contrast, its involvement in forming aneurysms in medium-sized vessels other than the cerebral and coronary arteries has not been reported. An 84-year-old Japanese man with COVID-19 was admitted to our hospital. The treatment course was favorable, and the COVID-19 treatment was completed by the 10th day. On day 14, pancreatic enzymes increased mildly. An abdominal computed tomography revealed a ruptured left gastric aneurysm after spontaneous hemostasis. Arterial embolization was performed. In this patient, a new left gastric aneurysm was suspected of having formed and ruptured during the course of the COVID-19 treatment. To the best of our knowledge, this is the first report of abdominal visceral aneurysm formation caused by COVID-19 in a medium-sized vessel, and it is necessary to remember that aneurysms can be formed at any site when treating this syndrome.

Keywords: COVID-19; abdominal visceral aneurysm formation; case report; left gastric aneurysm; medium-sized vessel.

(a) Non-contrast computed tomography of the abdomen on admission. Gallstones were found in the neck region of the gallbladder. However, there were no significant findings in the dorsal gastric or ventral pancreas. (b) Non-contrast computed tomography of the abdomen on day 14. A highly absorptive zone in the dorsal gastric/peripancreatic region (yellow arrows) and dilatation of the left gastric artery (red arrows) were observed.
