Abdominal macronodular tuberculomas: MR findings.

PURPOSE: Our goal was to determine the appearance of abdominal macronodular tuberculomas on MRI.

METHOD: MR findings of two patients with abdominal macronodular tuberculoma, one of the liver and the other in the kidney, were reviewed.

RESULTS

The two tuberculomas, histologically confirmed to have no calcification, hemorrhaging, or fibrosis, commonly showed low signal intensity on both T1- and T2-weighted images.

CONCLUSION

We report two cases of a macronodular tuberculoma in the liver and kidney, which is visualized as a region of hypointensity on T2-weighted MR images. This finding appears to be important in reaching a definitive diagnosis of an abdominal tuberculoma.
