Imaging Procedures and Findings
Coronal contrast-enhance CT shows a multilobulated intense enhancing mass in the left masticator space involving the left temporalis muscle and the left masseter muscle. Maxilla and zygomatic involvement and extension into the left orbit with displacement of the left glob inferiorly are seen. Right maxillary sinus mucosal thickening is noted.
Vascular anomalies can be classified as either tumors (most common being hemangiomas) or vascular malformations, which may be arterial, venous, lymphatic, or combined. Hemangiomas are the most common benign tumor of childhood with a predilection for the head and neck. Head and neck hemangiomas constitute 60% of all cases, followed by the trunk in 25% and the extremities in 15%.Hemangiomas are multiple in 20% of cases. Hemangiomas are seen much more commonly in girls than boys. Hemangiomas are usually not noticed at birth, most often presenting as a firm soft tissue mass a few weeks after birth. They typically have a rapid proliferation or growth phase in the first year of life, followed by spontaneous slow involution. By the age of 5 years, 50% have involuted, increasing to 70% by age 7 and 90% by age 9 years. Clinical history and physical examination make the diagnosis in 90% of the cases. Imaging is required with a large or atypical lesion for assessment of potential complications, surgical planning, and, in some cases, for evaluation of treatment.
