Pure intramuscular osteolipoma.

Yang JS, Kang SH, Cho YJ, Choi HJ - J Korean Neurosurg Soc (2013)

Bottom Line: We report a case of a histologically confirmed osteolipoma on the nuchal ligament independent of bone.The patient was a 51-year-old female who presented with a 5-year history of a painless, progressively enlarging mass on the posterior neck.The mass with dual components was totally removed under general anesthesia and no recurrence was observed after 6 months of follow-up.

ABSTRACT
Ossified lipoma or osteolipoma are rarely reported. It is defined as a histologic variant of lipoma that has undergone osseous metaplasia. Osteolipoma presents with a dominant osseous component within a lipoma. We report a case of a histologically confirmed osteolipoma on the nuchal ligament independent of bone. The patient was a 51-year-old female who presented with a 5-year history of a painless, progressively enlarging mass on the posterior neck. Computed tomography and magnetic resonance imaging showed a circumscribed mass compatible with fat between the C2 and C6 spinous processes with a large calcified irregular component. The mass with dual components was totally removed under general anesthesia and no recurrence was observed after 6 months of follow-up. We also reviewed the clinicopathologic features of previously reported osteolipomas in the literature and suggest that although osteolipoma is a rare variant of lipoma, it should be considered in the differential diagnosis when a lipoma of the posterior neck mixed with a bony component is encountered.

Figure 3: Grossly, the tumor consists largely of fat and calcification presented with the red bone marrow (black arrow).

Mentions: We performed tumor resection under general anaesthesia. The mass had a well-demarcated margin and the outer wall was very firm without adhesion to ligaments or paravertebral muscles. Gross examination revealed a well-circumscribed mass composed of adipose and bony tissue, with red bone marrow visible on the cut surface (Fig. 3). Histological study showed a lipomatous lesion with large foci of osseous metaplasia at the periphery of the mass; the bony portion was surrounded by mature adipose tissue (Fig. 4A). Microscopic examination of the red bone marrow showed a meshwork of bone trabeculae and hematopoietic marrow elements (Fig. 4B).
