Giant Cervical Occipital Lipoma: A Case Report.

Lipomas are common, well-circumscribed neoplasms of mesodermal origin, characterized by being slow, painless growths that are mostly subcutaneous, not invasive, and not recurring after surgery. Lipomas are the most prevalent kind of mesenchymal tumor, yet giant lipomas are rare in the cervical region and the occipital area. We report a 46-year-old female with diabetes insipidus was referred with a giant occipital cervical tumor, which she had noticed for 17 years and which had rarely given her any complaints of compressive symptoms. The clinical assessment indicated a firm, painless, and mobile swelling, which demonstrated features of venous ectasia, and there was no external ulceration. Ultrasonography and MRI of the neck revealed a large, subcutaneous fatty tumor with distinctive echographic features on both modalities, including hyperintense signals on T1 and T2 and no ring enhancement after Gadolinium injection. Due to the mass being smooth, round, and not attached to any structure, the patient underwent surgical enucleation under general anesthesia, resulting in full recovery without complications. Pathology revealed a benign adipose tissue tumor without liposarcoma, and there were no difficulties observed during follow-up for two years.
