Introduction. 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.
