Infantile Parotid Hemangioma: A Challenging Diagnosis.

Infantile parotid hemangiomas (IPH) are the most prevalent infantile parotid tumors. Imaging features are key for diagnosis. The following report details the case of a female neonate who developed a rapidly enlarging left submandibular mass. Imaging findings on ultrasound and MRI revealed marked vascularity and characteristic flow voids, consistent with the diagnosis of IPH. The presence of two smaller cutaneous hemangiomas further supported the diagnosis. Treatment with propranolol resulted in complete regression of the parotid mass without complications. This case highlights the valuable role of imaging in the evaluation of paediatric neck masses. The ability to recognize the distinct imaging features of IPH on ultrasound and MRI allows for an accurate diagnosis and avoids unnecessary interventions. In addition, it is important to note that propranolol remains a safe and effective first-line treatment.
