We describe a case of small adenocarcinoma which showed a distinctive MR finding consisting of two different zones of MR signal intensities (SI), central intermediate- and peripheral high-SI on T2-weighted MR imaging, due to different histologic subtypes. The central zone consisted of poorly differentiated adenocarcinoma and the peripheral zone consisted of well differentiated adenocarcinoma, with abundant clear cytoplasm. CT images showed a low density-, nearly homogeneous-nodule, which did not allow recognition of the presence of different histologic subtypes in the tumor. Contrast-enhanced CT and MR imagings showed slight enhancement. T2-weighted MR imaging was most effective in demonstrating uncommon findings of internal structures in the mass.
