Presentation
Fevers and right upper quadrant pain.
Patient Data







Multiple hypodense (30-50HU) lesions in the liver that demonstrate nodular, margins with internal, enhancing septations and measure 30-50HU in density. The lesions are predominantly subcapsular:
- segment IVa - 34 x 24mm
- segment VII - 33 x 24mm
- segment II - 31 x 31mm
A further 6mm hypodensity is noted in liver segment VII, it is unclear whether this is a related lesion or not. Segemental perfusion abnormalities are noted in the right liver on arterial phase and with liver segments II/III on portal venous phases.
Remaining imaged hollow and solid abdominal viscera is unremarkable. BIbasal atelectasis. Right pleural thickening/small pleural fluid collection.
Case Discussion
US guided aspiration of one the lesions was performed and Entamoeba histolytica (a protozoan parasite) was isolated.
