Volume increase of spleen in melanoma patients undergoing immune checkpoint blockade.

To find out whether treatment with immune checkpoint inhibitors (ICIs) results in volume increase of the spleen. We studied 49 stage III and IV melanoma patients with an indication for ICIs. Computer tomographic-assisted volumetry of spleens was performed.

Hyperdense pulmonary artery sign - detection of pulmonary embolism in patients with suspected COVID-19 using non-contrast chest CT.

The request for CT (computed tomography) diagnostic in patients with suspected COVID-19 pneumonia has become part of the daily clinical routine. We reported a case of a 61-year-old patient with flu-like symptoms and a suspected COVID-19 pneumonia. After a negative PCR-test (polymerase chain reaction), a non-contrast enhanced CT was performed which revealed a suspicious hyperdensity in the left pulmonary artery and a pneumonia in the left lower lobe.
