A case of a neuroepithelial cyst of the cerebellar vermis is presented. The cyst contained a viscous fluid and a xanthogranulomatous nodule. The fluid showed high signal on T1- and low signal on T2-weighted MR images. The xanthogranuloma showed mixed intensities with partial contrast enhancement. The correlation of the cyst contents and MR signals is discussed.

DEFINITION The histopathologic characteristics of ECD overlap xanthogranuloma and distinctions between the two are made on clinical and radiologic findings. Lipid-laden histocytes with foamy or eosinophilic cytoplasm infiltrate bones and various organs and generate a fibroblastic response that leads to critical organ failure. The histocytes are CD68+, Factor XIIIa+ CD1a-, S100-, and lack Birbec...

Introduction Solid masses in the testicular and paratesticular region are rare in the pediatric age group more so in infancy. Fibrous hamartoma of infancy (FHI), juvenile xanthogranuloma, capillary hemangioma, desmoid tumor, lipoma of the cord are some of the rare pathologic findings among the benign masses in the paratesticular location. We report a case of paratesticularhamartoma in a 10 mont...
