. Yolk sac tumors represent only 5%-7% of intracranial germ cell tumors, which comprise about 1% of all primary brain tumors in adults. Literature data about nonspecific imaging characteristics of these tumors are scant. We presented magnetic resonance imaging findings with diffusion-weighted imaging and proton magnetic resonance spectroscopy of this rare type of tumor in an adult patient. Case report. A 55-year-old man with progressive left side weakness, headache, dizziness and ataxia, underwent preoperative magnetic resonance imaging, diffusion-weighted imaging and proton magnetic resonance spectroscopy. After surgical resection and histological analysis, the final diagnosis of yolk sac tumor was established. Retrospective imaging analysis were performed in order to determine imaging and biochemical parameters that could be useful in the diagnostic evaluation of this tumor type. Conclusion. Though the imaging features of yolk sac tumor are not specific, morphoanatomical and metabolic imaging could offer the information that provides new insights into this tumor that may facilitate further therapeutic decision process and potentially provides better information regarding the disease prognosis
