    Associate Professor, Department of Diagnostic Radiology and Imaging, Chrisitan Medical College , Vellore, Tamil Nadu, India .
    Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is an infrequently encountered entity with only a handful of cases reported till date. The possibilities in such a case are either a malignant transformation of a benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumour of either a primary ovarian surface epithelial-stromal origin or a secondary from a primary gastrointestinal tract tumour. The importance of distinguishing between the two entities has significant bearing on subsequent therapeutic management. Read More

    Objective: To assess whether computed tomography (CT), magnetic resonance imaging (MRI), and neurosurgical evaluations altered the diagnosis or management of children diagnosed with benign macrocrania of infancy by ultrasonography (US).
