Metastatic choriocarcinoma of the testis mimicking ocular melanoma
MR examination revealed the presence of metastatic lesion in the right occipital lobe (Figure 1A) in a 23-year-old man with headaches, severe visual problems and right exophthalmus, associated with soft tissue choroidal mass of the right eyeball (Figure 1A and 1B) and T1W hyperintensity within the corpus viterum, compatible with hemorrhage due to retinal ablatia (Figure 1B). Melanomas are the most frequent malignant ocular neoplasms. Melanoma, renal carcinoma, thyroid carcinoma, and choriocarcinoma are however the most frequent hemorrhagic metastases within the brain parenchyma (1). Histologic evaluation revealed metastatic choriocarcinoma. Primary neoplasm of the testis was confirmed after additional examinations.
