“…Several sites have been reported: in the soft tissues of the trunk and the extremities [ 2 , 10 , 11 , 12 ], the joint space of the knee [ 13 ], the neck region [ 3 ] (including the retropharyngeal region [ 14 ], the parapharyngeal space [ 4 , 5 , 15 , 16 ], and the oropharynx [ 17 ]) the oral cavity (the most common site) [ 6 , 18 , 19 , 20 , 21 , 22 ], the skull base [ 23 ] and both the intraspinal [ 24 , 25 , 26 ] and intracranial cavities [ 27 , 28 , 29 , 30 ]. There only five cases described in the literature related directly to spine ( Table 1 ); three of them were intraspinal osteolipomas [ 24 , 25 , 26 ], another was located in the anterior aspect of C1-C2, considered the neck region [ 4 ], and the most similar to our case report, was located intramuscularly at the paravertebral cervical spine [ 31 ]. Our case report is the first male with spine-related osteolipoma, found in the posterior aspect of the cervical spine, independent from the cervical vertebra, incorporating the C3 posterior branch.…”

Cervical Paravertebral Osteolipoma: Case Report and Literature Review

Lipomas are the most frequent soft tissue tumors. Osteolipomas are a rare variant that can be difficult to diagnose. We report the case of a 66-year-old man consulting with a tumor of 2 years development in the right paravertebral cervical region. Neurologically, the patient had no sign of myelopathy or neurological focality. Magnetic resonance imaging showed a mass with a lipid component and calcifications inside within the right paravertebral musculature with a possible origin in the right C3 posterior root. A computed tomography scan and guided biopsy were performed, revealing hematic material and small bone spicules with no apparent neoplastic element. The tumor was totally removed, including the right C3 posterior branch, and was confirmed to be an osteolipoma on biopsy. The patient remains asymptomatic at 6-month follow-up. The osteolipoma is a benign tumor of soft tissue, characterized by lipoma areas with mature bone tissue differentiation, and even with hematopoietic marrow.

“…9 Jin Seo Yang et al reported a case of C2-C6 posterior muscular component Osteolipoma without presence of any extension into spinal canal. 10 The presence of an intraspinal Osteolipoma variant in the absence of accompanying spinal dysraphism is extremely rare. To the best of our knowledge, there is only one other reported occurrence of Osteolipoma in an intraspinal location.…”

Osteolipoma is a rare variant of the ubiquitous lipoma. Published literature appears in the form of isolated case reports affecting soft tissue structures in the head, neck and rarely affecting the spine. We present a unique instance of an intraspinal osteolipoma in the cervical spine, without evidence of accompanying spinal dysraphism and an atypical clinical presentation of isolated dysfunction. We describe the clinical presentation, operative procedure and post-operative outcomes with histopathological findings of this rare entity. A 61-year-old male presented with impaired sensation due to an intraspinal extradural ossifying lesion in the cervical spinal canal. The patient underwent excision of the lesion with complete resolution of symptoms. Ossifying lesion in the spinal canal may be frequent finding on radiological imaging but presence of possible adipose tissue in the lesion should raise suspicion of rare clinical scenario of an osteolipoma.

“…Presence of parosteal ossifying tumors adjacent to spinal vertebrae can be troubling due to the presence of nearby important neurological structures. Farley FA et al, Wilkinson CC et al, and Choi HJ et al ( 5 – 7 ) reported separate cases of cervical ossifying lipomas. Fortunately, all of these cases presented asymptomatically and underwent excision without complications or recurrence.…”

“…Parosteal lipomas are rare, accounting for 0.3% of all lipomas ( 4 ). To the best of our knowledge, only three cases have been reported involving the cervical spine ( 5 – 7 ) ( Table 1 ), and there have been none reported involving the thoracic spine.…”

IntroductionLipomas are derived from the mesodermal germ layer and are frequently encountered in adults, and account for almost 50% of all soft tissue tumors. Lipomas are classified based on their component tissues and location. A rare subtype, ossifying parosteal lipoma, accounts for 0.3% of all lipomas and occurs with intimate association with the underlying periosteum of the adjacent bone. Though lipomas are considered to be benign tumors, ossifying parosteal lipomas can manifest symptoms due to their location and relationship to nearby skeletal tissues. We herewith report the first known case of ossifying parosteal lipoma presenting in the region of the thoracic spine.Case presentationAn otherwise healthy adolescent boy presented with a 3-year history of a slowly enlarging painless thoracic mass. A general physical examination was normal, aside from a painless 10 cm mobile, hard mass along the posterior spine in the region of T4 through T6. Musculoskeletal and neurovascular examinations were normal. An ultrasound suggested a solid, cylindrically shaped mass with diffuse ossification. The mass was resected, and the pathology revealed ossifying parosteal lipoma without evidence of malignancy.ConclusionOssifying parosteal lipomas are rare, benign soft tissue tumors that should be added to the differential diagnosis of thoracic masses.
