Case 197: Hematoma

Diagnostic Categories:

Clinical Presentation:

33 year old pregnant woman with induced cesarean section.

CT: subcapsular, with THAD

Imaging Findings:

Multiphase CT scan of the liver shows a large heterogeneous collection which is indenting the liver parenchyma representing a subcapsular hematoma. It shows areas of increased  and mixed attenuation on non-contrast images representing mixed acute and subacute hemorrhage. Note medially adjacent hypervascular perfusion anomaly (THAD), typically due to compression of sinusoids by large hematoma and subsequent arterial buffer response causing zonal hypervascularity.
