A rare case of De Garengeot hernia: CT findings.

We report a case of "De Garengeot's hernia" (DGH), a rare condition that occurs when the inflamed appendix is localized inside a femoral hernia. The appendix may be involved in inflammatory or necrotic processes and the treatment is emergency surgery. It is usually discovered by chance during surgery. It occurs in 0.5%-5% of all femoral hernias. In 0.08%-0.13% of cases, the appendix can present inflammatory or necrotic processes due to the narrowness of the neck of the femoral canal; in these cases, an emergency surgery is required through a no standard surgical procedure. In the other cases, it is usually found accidentally during surgical repair of the hernia or more rarely diagnosed preoperatively by CT. Therefore, the purpose of our study is to report a case of DGH describing CT main findings in order to improve the preoperative diagnosis.

Latent tuberculosis reactivation in the setting of SARS-Cov-2 infection: The analysis of the radiologic features that help the diagnosis.

In Italy tuberculosis is a relatively rare disease and people coming from developing nations are usually affected. The radiological findings are variable and depend on the tuberculosis activity, if primary or post-primary. In literature, few data are reported about the co-existence of COVID-19 and lung tuberculosis. In this case report, authors describe the imaging features of latent lung tuberculosis in a patient with SARS-CoV-2 disease. The important role of CT imaging in identifying and diagnosing other infectious lung diseases presenting in the setting of the polymorphism and severity of SARS-CoV-2 disease is also discussed.
