2022年7月29日 · Intramuscular lipomas most commonly form deep within muscles in your: Arms. Chest wall. Head or neck. Shoulders. Thighs. Tongue. Trunk (pelvic area). What are the types of intramuscular lipomas? Certain tumor characteristics determine the type of intramuscular lipoma: Infiltrating intramuscular lipomas have muscle fibers growing through them.

Noncontrast magnetic resonance imaging (MRI) revealed a large irregular posterior shoulder mass, with a thin capsule and without any obvious septations or heterogeneity, extending between the supraspinatus and infraspinatus muscles and along the scapula, consistent with an intermuscular lipoma (Fig. 1, a-c).

Intramuscular lipoma is a very rare form of lipoma, known to be categorized as an infiltrating lipoma due to its tendencies to infiltrate the muscle or the synovium. Contrary to other subcutaneous lipomas, even after surgical removal, the rate of local recurrence ranges at a high rate from 50∼80% and differential diagnosis with liposarcoma is ...

When they occur under the enclosing fascia, they are called deep-seated lipomas. Infrequently, lipomas can arise inside the muscle and are called intramuscular lipomas. Intramuscular lipomas have been commonly investigated and categorized in the same group as other deep-seated and superficial lipomatous lesions.

2024年10月20日 · Intramuscular lipomas usually show the following features 1: hypodense soft tissue mass within the musculature. typically with Hounsfield measurements in the negative range (fat density) can show a striated appearance. can show thick intramuscular septae and interdigitations. usually, oval or fusiform shape but can vary. MRI

2020年12月4日 · Noncontrast magnetic resonance imaging (MRI) revealed a large irregular posterior shoulder mass, with a thin capsule and without any obvious septations or heterogeneity, extending between the supraspinatus and infraspinatus muscles and along the scapula, consistent with an intermuscular lipoma (Fig. 1, a-c).

Intramuscular lipoma is a rare type of deep-seated lipomas, which arise within the skeletal muscle fibres. It can arise in the background of history of trauma, obesity, chronic

2011年4月1日 · Seven of these lipomas were in the arm, one in the shoulder, and five in the forearm. Six lipomas were intramuscular, six intermuscular (three of them being attached to bone and labelled parosteal lipoma) and one epivaginal lipoma of the flexor tendon sheath.

Referred pain along the deltoid muscle is a common presentation of patients with shoulder pathology. Intramuscular lesions involving the deltoid muscle are often identified on routine ultrasound or magnetic resonance imaging of the shoul-der.

2011年1月1日 · Surgical excision is the best way to treat the symptomatic intramuscular, infiltrating lipoma. Careful preoperative evaluation and complete tumor excision with clear margins are most important to ensure successful surgical results. A lipoma is a benign mesenchymal tumor composed of mature fatty tissue.
