Intra-muscular hemangioma: A review

Intramuscular cavernous malformation in the temporalis muscle: Diagnosis and treatment of a rare tumor in a rare site

“…Unlike the common subcutaneous types of hemangioma, intramuscular hemangioma is not present at birth, is usually detected in the second or third decades of life, tends to grow slowly and progressively, and does not show spontaneous regression. Although the masseter muscle is the most common site of intramuscular hemangioma of the head region, 6 this lesion has been reported in other facial muscles such as the zygomatic, 7 buccinator, 8 extraocular, 9 and temporalis muscle. 10 …”

Intramuscular hemangioma in the zygomaticus muscle: A rare case report presentation and diagnosis

“…IMH usually occurs in the large muscles of the trunk and extremities. In the head and neck area, it occurs usually in the masseter muscle followed by temporalis and sternocleidomastoid muscles [ 2 ]. Intramuscular hemangiomas are categorized histologically depending on the vessel size into capillary hemangioma (small vessels <140 mm), cavernous hemangioma (large vessels >140 mm), and venous hemangioma with an incidence of 68 %, 26 %, and 6 % of all IMH respectively [ 8 ].…”

“…Hemangioma commonly occur on the skin and subcutaneous tissues. Dissimilar to cutaneous hemangioma, intramuscular hemangioma (IMH), which presents less than 1 % of all soft tissue hemangioma [ 2 ], slowly grows in size and does not tend to disappear spontaneously. It is usually noted in the second and third decades of life.…”
