“…Parosteal lipomas represent 0.3% of all lipomas [37,38]. Parosteal lipomas occur most commonly between the 5th and 7th decades [39]. Parosteal lipomas are generally located upon the diaphyses of long tubular bones such as the femur, humerus, tibia, and proximal radius [40].…”

Several different pathologies may play a role in the etiology of posterior interosseous nerve (PIN) palsy such as trauma, radial tunnel syndrome, tumors, vasculitis, septic arthritis, and rheumatoid synovitis. The most common atraumatic factor is the compression of the nerve through its anatomic path. Parosteal lipoma around the proximal radius is the leading solid tumor seen among the neoplastic lesions. Although it is common, there are only case reports or few case series reported in the current literature and a comprehensive review is missing. Herein a rare case of PIN palsy due to parosteal lipoma of the proximal radius is presented together with a thorough literature review. A 48-year-old woman was presented with elbow pain and wrist drop that lasted for ten months. Electrodiagnostic and imaging findings lead to a diagnosis of PIN palsy due to parosteal lipoma seated over the proximal radius. Total surgical excision was performed, and the patient had been followed up for one year. Removal of the lipoma failed to recover the patient's symptoms. We reviewed all the reported cases and discussed, epidemiology, clinical findings, imaging studies, electrodiagnostic studies, pathology, treatment and prognosis of PIN palsy due to parosteal lipoma.

Abstract. Lipomas are very common benign adipose tissue tumors that most often develop in subcutaneous tissue. A limited number of studies have described the characteristics of parosteal ossifying lipomas located in the fibula, cervical vertebrae and mandible. However, to the best of our knowledge, parosteal ossifying lipoma of the clavicle has not yet been reported. We herein describe the clinical symptoms, radiological and histological findings in a rare case of parosteal ossifying lipoma of the clavicle in a 40-year-old male patient. The characteristic histological appearance, together with computed tomography and̸or magnetic resonance imaging characteristics, should aid in the accurate diagnosis of such cases.

“…In the long bones, intraosseous lipomas are found in the metaphyseal and diaphyseal regions. 2 The sex predeliction in their tumors is controversial. Some authors have reported an equal sex predilection while some others have reported a slight male preponderance.…”

Intraosseous lipoma - A rare cause of ‘cystic’ lesion of calcaneum

et al. 2016

View full text Add to dashboard Cite

Intraosseous lipoma is an uncommon benign bone neoplasm with most of them detected incidentally on multimodality imaging while being evaluated for an unrelated pathology. Long and cancellous bones are commonly involved. This lesion can present a diagnostic challenge to those uninitiated in its appearence because they can be often mistaken for other benign or malignant bone lesions such as enchondroma, fibrous dysplasia, osteoblastoma, bone infarct, bone cyst and chondrosarcoma. Here we report a case of symptomatic calcaneal lipoma in a 50 year old lady who presented with heel pain. Plain X-ray suggested cystic lesion of calcaneum. MRI revealed the presence of intralesional fat and histopathological examination confirmed the diagnosis. We present this report for its rarity and the clinching MRI features of this lesion, the excellent prognosis and near negligible recurrence rates, so that misdiagnosis leading to unnecessary workup, biopsy and treatment may be avoided, especially in asymptomatic patients.
