Lipoma | Radiology Reference Article | Radiopaedia.org
2024年7月14日 · MRI is the modality of choice for imaging lipomas, not only to confirm the diagnosis, which is usually strongly suggested by ultrasound and CT but also to better assess for atypical features suggesting liposarcoma.
Lipoma and Liposarcoma | Radsource
Lipomas are the most common soft-tissue mass encountered, accounting for 50% of soft-tissue masses 1 and found in 2% of the population. Simple lipomas have a highly characteristic appearance on MR images and when typical can be diagnosed with 100% accuracy.
Imaging review of lipomatous musculoskeletal lesions - PMC
Superficial lipomas can almost always be diagnosed clinically. In cases where imaging is obtained, lipomas have a characteristic appearance on ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). Large lipomas may appear as a radiolucency on radiographs, but the finding is not diagnostic.
MR Imaging of Soft-Tissue Tumors of the Upper Extremity
2017年9月18日 · Magnetic resonance (MR) imaging can definitively diagnose lipomas, neural fibrolipomas, palmar fibromatosis, benign peripheral nerve sheath tumors, and glomus tumors. In most benign soft-tissue tumors of the upper extremity, characteristic MR imaging features combined with clinical history and epidemiologic knowledge can predict specific diagnoses.
The Value of MRI in Distinguishing Subtypes of Lipomatous …
Extremity lipomas and well-differentiated liposarcomas (WDLs) are difficult to distinguish on MR imaging. We sought to evaluate the accuracy of MRI interpretation using MDM2 amplification, via fluorescence in-situ hybridization (FISH), as the gold standard for pathologic diagnosis.
Underestimation of a Giant Lipoma on Magnetic Resonance …
This case report presents a subcutaneous giant lipoma in the upper arm weighing 350 g. Due to its long-term presence, the lipoma caused discomfort and pressure effects in the arm. Gross underestimation on magnetic resonance imaging (MRI) made its removal challenging and difficult.
Soft Tissue Masses: Evaluation and Treatment - AAFP
Lipomas that are 5 cm or larger in diameter or have atypical features on MRI, such as septations thicker than 2 mm or nodular soft tissue changes, should be evaluated for surgical excision. 35...
Spectrum of Fat-containing Soft-Tissue Masses at MR Imaging: …
2016年5月10日 · Lipomas are the most common benign fat-containing masses and demonstrate a characteristic appearance at magnetic resonance (MR) imaging. Less common benign soft-tissue masses include lipoblastoma, angiolipoma, spindle cell lipoma/pleomorphic lipoma, myolipoma, chondroid lipoma, lipomatosis of nerve, lipomatosis, hibernoma, and fat necrosis.
