Intramuscular cavernous hemangioma arising from masseter muscle: a diagnostic dilemma (2006: 12b)

Abstract

We report here a case of intramuscular cavernous hemangioma of the right masseter muscle in a 41-year-old woman-misdiagnosed preoperatively as parotid tumor-along with its imaging and pathologic findings. Preoperative diagnosis of intramuscular cavernous hemangiomas of the masseter muscle is problematic, in that they may be confused with parotid tumor or other muscular lesions. In a patient with soft-tissue mass suspected of representing a hemangioma, MR imaging may provide more specific information regarding the characteristics, the origin, and the extent of the lesion than other imaging modalities.

Intractable pain due to rectus abdominis intramuscular haemangioma

“…Intramuscular haemangiomas are infrequent, accounting for less than 1 % of all haemangiomas [4,5]. Intramuscular haemangiomas are mostly located in the extremities and the trunk, probably due to the large muscle bulk of these regions [1,5].…”

“…They correspond to capillary, cavernous and mixed type, respectively. These three histopathological types show clinical behaviour differences: the capillary type, characterised by predominantly capillary structures with proliferative activity, occurs more frequently, representing 68 % of IMHs and shows invasion of the surrounding tissue with a typically short clinical history; the cavernous type, characterised by large vessels with occasional mitotic activity, represents 26 % of IMHs and usually has a longer clinical history; the mixed type, and the least frequent with an incidence of 6 % is characterised by having both capillary and cavernous structures but resembles the cavernous type clinically [4][5][6]9]. Moreover, capillary haemangiomas are smaller and located mainly in the trunk and upper limbs while the cavernous type prefers the lower limbs [1].…”

“…Intramuscular haemangiomas are infrequent, accounting for less than 1 % of all haemangiomas [4,5]. Intramuscular haemangiomas are mostly located in the extremities and the trunk, probably due to the large muscle bulk of these regions [1,5]. In a series of 110 patients [6], most lesions were in the lower extremities (66 %) followed by the upper extremities (27 %) and the trunk (6 %), while the thigh was the most common single location (32 %).…”

A rare case of cavernous hemangioma of neck mimicking lipoma

“…Hemangiomas are classified into three groups, depending on their vascular structure: capillary, cavernous and mixed type. 3,7,8,10 A case of a cavernous hemangioma involving the muscles on the right side of the neck is reported here. Surgical treatment was used to achieve a successful outcome.…”

“…1 They are frequently seen on the trunk and extremities, but up to 20% of hemangiomas are located in the head and neck region. 1,4,6,8 Intramuscular hemangiomas often present in the second or third decade of life. Hemangiomas are classified into three groups, depending on their vascular structure: capillary, cavernous and mixed type.…”
