20.500.12556/DiRROS-30417 Posterior interosseous nerve lesion due to lipoma review of the literature and rare case presentation Poškodba posteriornega interosalnega živca zaradi lipoma Background. Posterior interosseous nerve lesion is a rare mononeuropathy of the upper limb. Atraumatic posterior interosseous nerve lesions are commonly caused by lipomas of the forearm, manifesting as slow-progressing wrist and finger drop. Patients and methods. In this review and case report study, we present a systematic review of the literature for patients presenting with posterior interosseous palsy due to lipomas and a rare case of patient with acute posterior interosseous nerve lesion caused by a lipoma. Our primary interest was in the timing of clinical presentation. For the review process, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Results. After reviewing the literature, we identified thirty patients with posterior interosseous nerve lesions caused by lipomas. In 28 patients, the symptoms presented progressively, ranging from 1 month to a maximum of 240 months. We found only one case of a patient with acute presentation and another patient with acute worsening of chronic weakness due to trauma. Conclusions. Atraumatic posterior interosseous nerve lesions are frequently secondary to forearm lipomas. In the majority of cases, the symptoms will develope progressively. However, in this study, we also report a rare case of a patient presenting with acute posterior interosseous nerve lesion due to a lipoma. posterior interosseus nerve lipoma compression acute true false true Association of Radiology and Oncology Ljubljana Angleški jezik Slovenski jezik Neznano 2026-06-24 12:31:21 2026-06-24 12:31:22 2026-06-25 03:51:30 0000-00-00 00:00:00 2024 0 0 str. 480-485, II no. 4 Vol. 58 Dec. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-12-01 616-006 1318-2099 10.2478/raon-2024-0041 210664707 https://doi.org/10.2478/raon-2024-0041 1 da1929fb-6fb7-11f1-98c5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46158 https://sciendo.com/article/10.2478/raon-2024-0041?tab=aurhors 1 d917909c-6fb7-11f1-98c5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46157 RAZ_Rojc_Bojan_2024.pdf RAZ_Rojc_Bojan_2024.pdf 1 1AEBA0E4B1E93ED6281BFDC731DB5019 e098dc313d897b2a826ede0156d0694c199a97cec192fdc71d1c71a27a503a32 2bcde1d6-6fb8-11f1-98c5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46159 Društvo radiologije in onkologije Onkološki inštitut Ljubljana 0 0 0
