Intraocular Medulloepithelioma: AIRP Best Cases in Radiologic-Pathologic Correlation

Abstract

Editor's Note.-RadioGraphics continues to publish radiologic-pathologic case material selected from the American Institute for Radiologic Pathology (AIRP) "best case" presentations. The AIRP conducts a 4-week Radiologic Pathology Correlation Course, which is offered five times per year. On the penultimate day of the course, the best case presentation is held at the American Film Institute Silver Theater and Cultural Center in Silver Spring, Md. The AIRP faculty identifies the best cases, from each organ system, brought by the resident attendees. One or more of the best cases from each of the five courses are then solicited for publication in RadioGraphics. These cases emphasize the importance of radiologic-pathologic correlation in the imaging evaluation and diagnosis of diseases encountered at the institute and its predecessor, the Armed Forces Institute of Pathology (AFIP).

Intraocular medulloepithelioma: an unusual and challenging entity in paediatric population

“…Intra-tumoural cysts are considered as pathognomonic feature readily picked by MRI Furthermore, any extra-ocular or extra-scleral invasion of tumor can be caught on this imaging modality. 6 Differential diagnosis of medulloepithelioma includes other ocular tumours such as retinoblastoma, malignant melanoma, or secondary involvement of orbit in Ewing sarcoma, Rhabdomyosarcoma, and Neuroblastoma. Histologically, medulloepithelioma is classified into teratoid and nonteratoid types.…”
