Ultrasound features of deep-seated lipomas

چکیده
PURPOSE: The objective of this study was to describe the sonographic features of deep-seated lipomas. METHODS: A retrospective review of the sonographic features of 64 deep seated lipomas in 64 patients (43 females, 21 males, mean age 46.5, range 16-77 years) seen over an 8-year period (1998-2006) was undertaken. RESULTS: Features evaluated were location, size, shape, marginal definition, internal echogenicity, including the presence of intermingled muscle fibres and linear internal echoes, acoustic transmission and vascularity. Confirmation was histological in 37 (58%) cases and by typical magnetic resonance imaging (MRI) appearance in 27 (42%) cases. CONCLUSION: The results show that although the features of deep-seated lipoma are more variable than those reported for subcutaneous lipomas, the presence of thin internal echoes in conjunction with other less specific features should enable a correct diagnosis.

Deep-seated ordinary and atypical lipomas: histopathology, cytogenetics, clinical features, and outcome in 215 tumours of the extremity and trunk wall.
Deep-seated lipomas are often atypical histologically and are considered by some to have a high risk of recurrence after excision. We reviewed 215 deep-seated lipomas of the extremities and trunk wall with reference to histology, cytogenetics, clinical features and local recurrence. We classified tumours with atypical features and/or ring chromosomes as atypical lipomas. These were more common ...

Lipomas are the most common type of soft tissue mesenchymal tumors. They are typically located subcutaneously and consist of mature fatty tissue. 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 ...

BACKGROUND Lipomas can be categorized into deep and superficial lipomas according to anatomical depth. Many cases of forehead lipomas are reported to be deep to the muscle layer. We analyze ultrasound in delineating depth of forehead lipomas. METHODS A retrospective review was performed for all patients who underwent excision of forehead lipomas between January 2008 and March 2013 and for who...

Lipomas are the most common benign mesenchymal tumors. They are located either subcutaneously or under the investing fascia in intramuscular or intermuscular regions. The reported frequency of intramuscular lipomas among all benign adipocytic tumors is 1.0%–5.0% and for intermuscular lipomas is 0.3%–1.9%. The frequency of these lesions is the same in all age groups, but in adults deep seated-...
