They occur mostly on the neck, trunk and extremities, but can occur anywhere on the body. Lipomas are composed of fat cells that have the same morphology as normal fat cells, and there is a framework of connective tissue. Angiolipomas have a vascular component and can beEnder at cold room temperature. These often require excision, while other lipomas should be excised only when they are considered as disfiguring.
BACKGROUND AND OBJECTIVE: Pericellular lipomas are rare tumors. Few reports have included their imaging characteristics. In addition, little is known about their evolution. Our goal was to describe the imaging characteristics of seven cases of pericilosal lipoma diagnosed in utero and followed after birth. Methods: We examined seven cases of pericallosal lipoma diagnosed by obstetric ultrasonography (n = 7) and examined by fetal MR imaging (n = 5).
It often takes longer to observe the lipomas found in deeper tissues, and these tumors can be quite large when they are actually discovered. Deep lipomas also tend to be less mobile. Before a physical exam, your doctor will tell you about your state of health and your current state of health. He or she will want to get a good history of the problem from your point of view, especially how long the mass has been there and what are the symptoms - such as pain - associated with it? s. During the physical examination, your doctor will feel the mass, check his size and consistency, as well as his mobility.
Fetal MR imaging confirmed the fat content and the location of the lesion in all five cases. He showed the choroidal extension in two patients and the type of callosal abnormality associated with another patient better than the ultrasound. In two patients, the lipoma increased, as revealed by subsequent postnatal MR imaging. The results of the neurological examinations remained normal for the five surviving patients with an average follow-up of 3 years (1 month - 9 years).
It is more likely that lipomas are at the extreme benign spectrum of tumors, which, at the malignant end, include liposarcomas (see Pathophysiology). As more than half of the lipomas encountered by clinicians are subcutaneous, most of this article will be devoted to this subgroup. Additional information on other locations (eg, intramuscular, renal, gastrointestinal GI) will be included where appropriate.
A lipoma is slow-growing, benign growth of fat cells. It is contained in a thin, fibrous capsule and found right under the skin. A lipoma is typically not tender and moves around easily with…
