A rare case of huge congenital parieto-occipital teratoma in a female infant: An unusual site of occurrence

Abstract

Teratomas are considered the most common congenital tumors located on the dorsal midline and arise from cells derived from more than one germ layer (i.e. ectodermic, endodermis and mesodermic) at different regions of the body. Those in the head and neck regions are considered rare with an incidence of 1-3.5% of all cases. Imaging provides critical information that helps in formulating differential diagnosis even though, history and physical examination provides critical information in making the diagnosis. A successfully surgically treated case of an usually huge parietooccipital teratoma in a 40 days old girl was presented with emphasis on the importance of imaging in diagnosis and management.
