Case list for Sarcoidosis
There are 3 CT cases with this diagnosis.
Arterial phase CT shows multiple well-defined non-enhancing hypodense foci of similar size, which are most conspicuous on the portal venous phase and are isodense to liver parenchyma on the equilibrium image. The lateral most lesion demonstrates a hypovascular linear perfusion anomaly.
Even though is a nonspecific imaging finding, the differential diagnosis can be limited to metastatic disease and microabscesses. Biopsy of one of the lesions confirmed non-necrotizing granulomas with fibrosis typical for sarcoidosis, no signs of active infection.
Multiphase CT reveals multiple small hepatic granulomata. These are hypodense in the portal venous phase, and iso- to hypodense in all other phases. Liver shows contour deformities, representing cirrhotic transformation.
Note also the splenic hypodense foci and the pulmonary nodules, suggesting sarcoidosis in these organs as well.
