Case History: 62-year-old female with right upper abdominal pain.
62-year-old female with right upper abdominal pain.
Figure 1. US revealed a 40 Ã 35-mm hyperechoic rounded sub-capsular mass in left hepatic lobe segment III.
Figure 2. CT scan demonstrated hypodense fat attenuates.
Figure 3. MRI showed high signal intensity (hyperintense) on T2-weighted magnetic resonance image.
Figure 4. MR imaging sequences aid in the detection of fat, including fat suppression sequences appeared well defined hypointense.
Figure 5. Chemical shift imaging with opposed-phase gradient-echo sequences showed bright signal in phase.
Figure 6. Signal dropout in out of phase, which confirmed the presence of fat in the liver lesion.
Diagnosis: Hepatic lipoma
The etiology of these lesions is not well defined and their clinical manifestations vary, but often they are asymptomatic.
Many authors do not recommend more aggressive diagnostic procedures, such as needle liver biopsy and operation.
