Multifocal nodular steatosis mimicking liver metastasis
We report a case of a 56-year-old male under investigation for large lytic lesion at clivus. After lesion resection, patient was referred to abdominal computed tomography scan for metastasis screening. The lesion was posteriorly characterized as chondroid chordoma at histopathology examination.
On non-enhanced computed tomography, multiple hypottenuating nodules of different sizes were seen; the largest nodule had 3.2cm. On post-contrast phases lesions had similar enhancement to adjacent liver parenchyma. However, no significant mass effect or invasiveness were seen, once vascular structures (liver veins and portal branches) crossed such nodules without dislocation or invasion. Our findings, although not pathognomonic, suggested the hypothesis of multifocal nodular steatosis.[…]
