What is more interesting in this case is the finding on chest radiograph. Although chest radiograph is insensitive to pulmonary embolism, there are signs that may point to it such as Westermark's sign, elevation of hemidiaphragm, effusion, Hampton's hump, and so called CT angiogram sign as seen in this patient - parts of the right truncus intermedius filled with thrombotic material are more transparent and there is an abrupt tapering of its bottom end.

However, CT and subsequently PET-CT (courtesy of As. Kovacova, Institute of Nuclear Medicine) showed large soft tissue mass surrounding the distal esophagus. The patient underwent surgery with resection of the mass and histology showed normal pancreatic tissue.

They are more abundant in lower to middle lung zones. In the brain of this young adult, there are several hypodense cortico-subcortical areas that represent septic emboli.

Abdominal radiograph shows several small air-fluid levels with no dilation of the bowel. An ultrasound image is typical - abundant intraluminal fluid and edema of valvulae conniventes (Kerckring's folds) that increase echogenicity and acquire layered appearance.

The margins of the keratocysts are smooth and well-defined.

The rectus inferior muscle remains in the orbit. The right maxillary sinus is filled with blood.

In the right adrenal gland, there is also a mass which contains a nodule of fat density and therefore it is a myelolipoma as well.
