An intramuscular lipoma is a benign tumour consisting of fatty tissue that grows inside muscle tissue, and typically can develop in the head, neck, legs and trunk of middle aged adults. Usually, these lumps will be diagnosed following x-rays and a doctor’s examination. Surgery is not usually needed as the condition is not considered life-threatening, but may be an option if the tumour causes a problem by pressing against a nerve. In the case of an intramuscular lipoma, surgery can be a little more difficult and intricate, with a greater possibility of regrowth if not totally removed during the procedure.
Just to be clear, an intramuscular lipoma consists of a fatty tumour growing within the muscle tissue, whereas an intermuscular lipoma develops between groups of muscles, although in both instances, the tumour is exactly the same.
The tumour manifests as a lump, no larger than 1 to 2 centimetres across in the case of an intramuscular lipoma. As the location is within muscle fibres, the chances of being uncomfortable are higher than would be the case with other lipoma types, so a visit to a medical practitioner is highly likely and sensible.
The fatty lump is plain to see via an x-ray, so diagnosis is straightforward, with tests, including blood tests, utilised to confirm whether the growth is benign or malignant. As mentioned, surgery is not generally required, but may be a choice if the lipoma is causing pain or discomfort.
Intermuscular lipomas are easily removed by surgical procedures, but intramuscular lipomas are much more difficult to remove because the surgery involves the cutting of the muscle in which the growth develops. In some instances, this may prevent the total removal of the tumour so that no lasting damage occurs to the muscle involved. This means that if some of the growth remains, then it may possibly regrow to its original proportions.
Successful lipoma removal surgery may only require one or two days recovery time, and the tumour should not return, but for sufferers where the total removal is impossible, further x-rays and surgery may well be needed.
