The area is draped with sterile napkins. Local anesthesia is given with 1% or 2% lidocaine with epinephrine, usually in bulk. Infiltration of the anesthetic into the subcutaneous area surrounding the operative field creates a field block. Small lipomas can be eliminated by electrolysis. An incision of 3 mm to 4 mm is made on the lipoma. A curette is placed inside the wound and used to release lipoma from the surrounding tissue.
Intense lipomas can cause pain, muscle atrophy and lameness by interfering with movement. Unlike normal lipomas, infiltrating lipomas can be difficult to completely eliminate and repel often. Invasive lipomas are the most common in Labrador Retrievers and Doberman Pinschers. All infiltrating lipomas do not cause problems.

During the lipoma nucleation for small benign tumors, the doctor creates micro-incisions on the skin layer that expands on growth. This is done through the use of a thin scoop and gouge stem shape known as a medical grade curette. The curette gives the surgeon the ability to separate the lipoma from the skin around the tumor and effectively eliminate all growth. Once this operation is complete, the small wound is covered with a garment under pressure for good healing.
However, they can appear in other areas of the brain, usually close to the median line. Lipomas vary in size. Single or multiple tumors may be present. A lipoma can cause no symptoms and often goes unnoticed until an examination is done for other medical reasons. Conservative treatment is generally recommended because these tumors are benign and rarely cause symptoms. Surgery may be suggested in some cases.

Utero and postnatal follow-up images (case 3). B, image obtained at birth. Sagittal image spin-echo turbo T1 (350/16/1) confirming the presence of lipoma and the agenesis of the corpus callosum. C, image obtained at birth. Front view turbo spin-shot image in T1 (350/16/1) shows the lateral extension of the lipoma. D, image obtained at the age of 3 years. Sagittal medial spin-echocardiogram weighted T1 (450/15/1) shows the growth of lipoma. E, image obtained at the age of 3 years. Similar results are revealed by the weighted sequence in T1 turbo spin-etch T1 (450/15/1). A mid-sagittal view Spin-echo weighted T1 sequence (400/17/1) shows a typical lipoma and an incomplete corpus callosum.
