Patient Data
A multiseptated cystic lesion is noted at the superficial lobe of the right parotid gland and extending anteriorly superficial to the masseter, as well as through the stylomandibular space to the deep lobe of the gland and right parapharyngeal space.
This lesion measures 4.4 x 4 cm in axial dimensions. It shows fluid-like signals in all pulse sequences, including free diffusion. Only minimal septal enhancement is noted.
Case Discussion
Radiological features are in favor of intraparotid cystic lymphangioma extending to the right parapharyngeal space. It is one form of congenital lymphangiomas which are most commonly occur in the cervicofacial regions in pediatric age group.
It appears as a fluid-containing lesion which can be unilocular or multilocular and can be multispatial. Most commonly presents as a painless swelling, yet it can be complicated by hemorrhage, infection or mass effect.
