“…Lipomas most frequently settle in subcutaneous tissue and also, they can be observed at deep locations under the fascia, i.e., where there is adipose tissue [4]. Deep lipomas are defined by localization as intermuscular, intramuscular, parosteal, and interosseous [5]. Parosteal lipomas occur most commonly among patients over the age of 40, and they are observed primarily in the proximal radius, humerus, femur, clavicular, and pelvis [6].…”

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.

“…It is composed of mature adipocytes admixed with collagen streaks and is often well demarcated from surrounding connective tissue. Histological variants of lipoma include angiolipoma, myolipoma, angiomyolipoma, myelolipoma, chondroid lipoma, spindle cell and pleomorphic lipoma [3,4] which are distinguished microscopically with ordinary lipomas(as reported in this case). Adequate surgical excision is the treatment of choice for intraoral and extra oral lipoma.…”

“…Lipoma comprises 4-5% of all benign tumors in the body whereas oral lipoma constitutes 2.2% of all lipomas and 2.4% of all benign tumors of oral cavity [2]. They are usually asymptomatic unless any neurovascular structure is compressed [3]. The well encapsulated tumors are freely movable beneath mucosa and MRI is helpful in clinical diagnosis of these along with clinical findings [4].…”

Lipoma Compressing the Sciatic Nerve in a Patient With Suspicious Central Post-stroke Pain

et al. 2017

Lipomas are mostly located in the subcutaneous tissues and rarely cause symptoms. Occasionally, peripheral nerve compression by lipomas is reported. We describe a case of a 59-year-old man with a left-middle cerebral artery infarction who was newly diagnosed as right basal ganglia and thalamic intracranial hemorrhage. He had neuropathic pain in the left arm and leg that was suspected to be central post-stroke pain. The administration of pain medication brought only temporary symptom relief. Nerve conduction and electromyography studies revealed left L5 radiculopathy and he showed a positive ‘sign of the buttock’ in the left hip. Left-hip magnetic resonance imaging revealed an intermuscular lipoma compressing the sciatic nerve. After surgery, the range of motion in the left hip joint was significantly increased, and the patient's pain was relieved.
