We report a case in a two and a half month old boy presenting a mass in the right parotid gland. Sonography showed a vascular tumor. Magnetic resonance imaging showed an expansive process of the parotid gland measuring 61 x 39 mm taking the contrast with hypo signal in T1 and hyper signal in T2-weighted images. The parotid was extirpated with preservation of the facial nerve. Microscopically the diagnosis of cellular hemangioma associated with CMV infection was made. Hemangiomas of the parotid gland is frequent; the most common tumor in children; the association of juvenile hemangioma of the parotid gland and cytomegalovirus (CMV) is extremely rare: a single case was reported in the literature. The pathologic significance of this association is still discussed, although several experimental studies suggested a relationship between the infection by the cytomegalovirus and this tumor. Our objective is to describe the anatomo-clinical aspects of this lesion and to elucidate the pathologic significance of this association.
