RESUMO
Gallstone ileus (GI) is a rare cause of acute abdomen in an emergency setting and a rare complication of cholelithiasis in the elderly, with a female prevalence. Radiologists play a key role in the diagnosis and management of this condition and, with a multimodal approach, diagnostic accuracy usually increases. Spontaneous resolution of GI has previously been reported for stones smaller than 2 cm. Gallstones usually require surgical management; however, in patients with comorbidities and at high risk of surgical complications, a conservative approach may be considered. Herein, we report the case of an 84-year-old woman who came to the emergency department with an acute abdomen pain caused by a GI, with a 2.6 cm gallstone that was revealed on computed tomography and which was followed by diagnostic imaging with spontaneous resolution.
RESUMO
Imaging plays an important role in the detection of coronavirus (COVID-19) pneumonia in both managing the disease and evaluating the complications. Imaging with chest computed tomography (CT) can also have a potential predictive and prognostic role in COVID-19 patient outcomes. The aim of this pictorial review is to describe the role of imaging with chest X-ray (CXR), lung ultrasound (LUS), and CT in the diagnosis and management of COVID-19 pneumonia, the current indications, the scores proposed for each modality, the advantages/limitations of each modality and their role in detecting complications, and the histopathological correlations.
