Case list for Hematoma
There are 2 CT cases with this diagnosis.
61 year old woman with spontaneous subcapsular hematoma of the right lobe. No trauma as per the patient. No underlying mass identified up to 9 months after initial event. Typical scalloping of adjacent liver parenchyma. Spontaneous hematoma is indistinguishable from traumatic hematoma. Note perifocal transient hypervascular perfusion anomaly on arterial phase due to mass effect of subcapsular hematoma (arrowheads).
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.
