The MRI sequences:
- small well-defined lesion of the segment 7 of the liver, of low signal on T1, high signal on T2 and T2 fat sat with progressive discontinuous nodular peripheral enhancement on arterial phase, more centripetal fill-in on portal venous phase with almost complete fill-in on delayed sequences in keeping with hemangioma.
- small well-circumscribed, lobulated pancreatic lesion at the corporeocaudal region. It elicits a high signal on T1 IP and T2, attenuated on T1 OP and T2 fat sat with no enhancement on postcontrast sequences highly suggestive of lipoma
- small simple left renal cysts
Case Discussion
MRI features of small pancreatic lesion of high signal intensity on T1 IP and T2 attenuated on T1 OP and T2 fat sat most consistent with a small pancreatic lipoma. On CT (not shown), the attenuation value was around (- 80 HU).
Pancreatic lipomas are rare benign tumors, rarely symptomatic and most often detected incidentally on cross-sectional imaging for another purpose. On the MRI, they follow the signal intensity of the fatty tissue.
