On a contrast-enhanced study, an angiolipoma shows marked enhancement as a result of its intense vascularity.
On the other hand, as for angiolipoma with bleeding, MRI seems to show an inhomogenous isointense mass on T1-weighted images.
Based on microscopical features they are classified into classic lipoma, fibro lipoma, angiolipoma, spindle cell lipoma, and pleomorphic, myxoid, sialolipoma, and intramuscular lipomas [3].
Angiolipoma is a rare variant of lipoma; its distinctive feature is prominent vascularity.
The radiological differential diagnosis of both benign and malignant fat containing tumours, including atypical lipoma, haemangioma, angiolipoma, and liposarcoma, therefore warrants histological characterisation prior to excision.
On histology, the IAC tumor showed nerve tissue with fatty infiltration (figure 2), while the forearm tumor showed an angiolipoma. At the 6-month followup, the patient's tinnitus had disappeared, her facial weakness had improved to House-Brackmann grade II status, and a repeat MRI detected no evidence of tumor recurrence.
(1) According to histopathological findings, they are sub classified into conventional lipoma, fibrolipoma, angiolipoma, fusiform cell lipoma, myolipoma and pleomorphic lipoma.
The benign hemangioma group consisted of 13 typical hemangiomas, 6 atypical hemangiomas, 1 angiolipoma, and 1 angiomatosis.
Lipomas can occasionally be altered by the presence of other mesenchymal elements, such as fibrous tissue (fibrolipoma), smooth muscle (myolipoma), capillaries (angiolipoma), and collagen-forming spindle cells (spindle-cell lipoma).
