Postoperative Computed Tomographic Assessment of the Complete Resection of an Infiltrative Lipoma Compressing the Spinal Cord in a Dog

Infiltrative lipomas, which are locally invasive tumors composed of well-differentiated adipocytes, histologically identical to lipomas but have a tendency infiltrate adjacent muscle and fibrous tissue without metastasis, such as muscle; connective tissue; bone; and, in rare cases, peripheral nerves the spinal cord. They differ from liposarcomas yet also exhibit neoplastic cell infiltration often recur despite surgical removal. A 10-year-old spayed Maltese female dog presented with hindlimb paresis back pain for two months. Computed tomography magnetic resonance imaging revealed an extensive fatty mass impinging on vertebral canal, compressing cord, extending into surrounding layers thoracic cavity. The was surgically removed, subsequent postoperative computed confirmed complete removal using Vitrea® advanced visualization fat measurement. Histopathological analysis that infiltrative lipoma. patient’s symptoms completely resolved after surgery, no recurrence reported at 2-year follow-up. This case highlights benefits combined automated measurement technique determine whether reoperation is necessary or predict patient prognosis by identifying potential residual lipoma post-surgery.
