Intramuscular haemangiomas of the head and neck region are rare. They may present as an incidental finding, a mass or swelling, pain, tenderness, limitation of movement or cosmetic deformity. Treatment depends on the clinical signs and symptoms. Because of the apparent rarity of this lesion, we report a case of an incidental finding of multiple radio-opacities in a dental panoramic tomograph that was diagnosed as cavernous haemangioma in temporalis muscle with multiple phleboliths.
Intramuscular haemangiomas (IMH) are uncommon tumours in the head and neck region, occurring most often in the trunk and extremities. Haemangiomas located in skeletal muscles represent less than 1% of all haemangiomas. Of these, less than 20% occur in the head and neck region, predominantly in the masseter and trapezius muscles. Intramuscular haemangiomas in the temporalis muscle are rare. Previously reported cases include cavernous, capillary and venous haemangiomas. Cavernous haemangiomas in the muscles of the head and neck can be clinically distinguished from the more aggressive capillary ones. Complications associated with IMH are rare, but include haemorrhage or functional deficits. In this paper, we report a case of an incidental finding of multiple radio-opacities in a dental panoramic tomography (OPG) that is diagnosed as cavernous haemangioma in temporalis muscle with multiple phleboliths.
A 57-year-old female was referred to our oral and maxillofacial surgery unit by her general dental practitioner with symptoms of pain originating from the upper right quadrant and a finding of multiple radio-opacities in a dental panoramic tomography (DPT/OPG) in and around the right maxillary tuberosity region (Figures 1 and 2).
