(5 img) http://atlas.mudr.org/RSS/Cholecystostomy-acute-cholecystitis http://atlas.mudr.org/Case-images-Chondrohamartoma-of-lung-ground-glass-1789 Plain chest radiograph shows a well-defined opacity in the left lower lung field. CT confirmed a well-defined nodule in the periphery of the left lower lung lobe most likely consistent with chondrohamartoma. Note also almost diffuse ground-glass opacities in centrilobular location - an unspecific finding.

(5 img) http://atlas.mudr.org/RSS/Merkel-cell-carcinoma-recurrence http://atlas.mudr.org/Case-images-Carcinoma-of-sigmoid-colon-metastasis-in-liver-1787 CT shows multiple liver metastases with a typical appearance of hypodense center surrounded by hyperdense rim. CT also confirmed tumorous thickening of sigmoid colon. Initially, the ultrasound image of hypoechoic lesions in the liver parenchyma was mistaken for liver cysts and segmental thickening of sigmoid colon for diverticulitis. Liver metastases may appear on ultrasound almost anechoic and therefore mimic cysts, if the liver is steatotic as was in this case.

Subsequent CT shows airspace consolidation consistent with acute bronchopneumonia, which was confirmed by a biopsy requested by the physician. Follow-up CT shows regression of bronchopneumonia infiltrates leaving a small area of fibrous changes. Unfortunately, next CT showed recurrence of bronchopneumonia.

CT shows, that it is caused by a right-sided diaphragmatic hernia which contains right liver lobe, gallbladder with gallstones, and large bowel. It causes compressive changes of the right lowe lung lobe. This hernia was treated surgically with a good result which can be appreciated on the last two CT images.

It has somewhat increased density. Ultrasound showed that the nodule has increased echogenicity and is homogeneous and well-defined. MRI study concluded, that a presence of atypical angiomyolipoma (with limited fat content) is more likely.

The gallbladder tumour infiltrates the hepatic flexure, both structures are connected by a fistula.

The cause is acute exudative pancreatitis. Note also bilateral pleural effusion and compressive changes of adjacent lung parenchyma.

Moreover, there is a cluster of popcorn-like calcifications most likely in a uterine fibroma.

Note also large amount of blood in the pericardial sac.
