What is a intraosseous lipoma?
Intraosseous lipoma is one of the rarest benign bone tumour. They have been identified in the tibia, fíbula, metatarsals, and calcaneal. They are easily misdiagnosed as the clinical presentation is nonspecific and can mimic other ligamentous or soft tissue injury.
How is intraosseous lipoma treated?
Most of the patients would benefit from non-surgical treatments. But if this is not the case, surgical treatment is indicated. In conclusion, curettage and autogenous bone grafting is an easy and effective method for the surgical treatment of calcaneal intraosseous lipomas.
Can a lipoma be on a bone?
Lipoma can be located in the intraosseous region or adjacent to bone and referred to as intraosseous, parosteal, or periosteal lipoma respectively. Those that are in such sites may contain osseous and/or chondral components [5, 6].
Can lipoma cause back pain?
Episacral lipoma is a significant and treatable cause of acute and chronic low back pain. Episacral lipoma occurs as a result of tears in the thoracodorsal fascia and subsequent herniation of a portion of the underlying dorsal fat pad through the tear. This clinical entity is common, and recognition is simple.
What is intraosseous hemangioma?
Intraosseous hemangioma is a rare bone tumor accounting for 0.7% to 1.0% of all bone tumors. It can occur at all ages but is most common in the fourth and fifth decades of life and has a female preponderance (3:1) [1]. Intraosseous hemangiomas are usually found in the vertebral column and rarely seen in the calvarium.
What do lipomas attach to?
These masses are not typically attached to underlying muscle fascia. Lipomas are composed of lobulated, slow-growing, mature adipose tissue, having minimal connective tissue stroma. They are commonly enclosed in a thin, fibrous capsule.
Is lipoma benign or malignant?
A lipoma is a non cancerous (benign) lump that forms due to an overgrowth of fat cells. You can get a lipoma anywhere on the body where you have fat cells. Lipomas are not cancer.
Can a lipoma affect your spine?
Spinal Lipomas Purely subpial lipomas are rare, and although they can occur anywhere along the spine they tend to affect the cervical region in children when they are not in the lumbosacral spine.
What are intraosseous lipomas composed solely of fat?
Intraosseous lipomas composed solely of fat (Milgram stage 1 lesions) are radiolucent, well-circumscribed lesions that frequently are associated with mild, focal, expansile remodeling. 1 On MRI, the lesion is geographic, rounded, without cortical interruption, with a peripheral rim of high signal intensity on T1- weighted images (1a,1b).
Is intraosseous lipoma diagnostic difficult?
Intraosseous lipoma is an uncommon tumor of bone with indistinct radiologic features that makes it diagnostically challenging to radiologists and pathologists. There is a need to familiarize these physicians with the radiographic and pathologic features of this lesion for the correct diagnosis. We d …
Is lipoma of the femur sclerotised?
Lipomas located in the proximal femur may be surrounded by a relatively extensive area of sclerotisation [13]. Lesions in the intertrochanteric area of the femur need to be differentiated from liposclerosing myxofibrous tumor, a very rare, benign fibro-osseous lesion with mixed histology, which may include components of lipoma [14].
What is the pathophysiology of calcaneal intraosseous lipoma?
Calcaneal intraosseous lipoma is an uncommon benign bone tumor which, as it slowly expands and remodels adjacent osseous structures, acquires a typical appearance that should be readily diagnostic on plain radiographs and MRI.
