It is essential to distinguish benign from malignant lesions that require further investigation.Objectives: The aim is to describe the imaging characteristics to facilitate the practical differentiation between malignant and benign incidental findings in bone marrow.Methods: A narrative literature review focusing on a pattern-based approach to the spinal and extraspinal skeleton.Results: The signal characteristics, morphology, and location of the bone marrow incidentaloma are crucial for classifying the lesion. In the spine, classifying the lesion as diffuse, focal, microfocal, or regional helps limit the differential diagnoses. Osteolytic lesions are hypointense on T1w- and hyperintense on T2w-imaging; sclerotic lesions are signal-free on all sequences; and fatty lesions are hyperintense on both T1w- and T2w-imaging. The presence of micro- or macroscopic fat within a lesion is a criterion for benignity.Conclusion: By using a few MRI sequences and correlating them with X‑ray and computed tomography (CT) images, it is possible to reliably classify incidental bone marrow lesions.","PeriodicalId":74635,"journal":{"name":"Radiologie (Heidelberg, Germany)","volume":" ","pages":"784-792"},"PeriodicalIF":0.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148521553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In symptomatic women, uterus-preserving treatment strategies are becoming increasingly more important.Standard radiological methods: Contrast-enhanced magnetic resonance imaging (MRI) is the imaging standard for preprocedural planning. It accurately enables assessment of the number, size, location and vascularity of fibroids while excluding relevant differential diagnoses.Methodological innovations: Uterine artery embolization (UAE) is an established minimally invasive uterus-preserving treatment. Recent technical advances include transradial access, optimized angiographic protocols and modern calibrated embolic agents.Performance: Randomized trials demonstrate sustained symptom relief and improved quality of life with a low complication rate. The use of UAE achieves high fibroid devascularization rates but is associated with higher reintervention rates than myomectomy.Achievements: The UAE is an evidence-based alternative to surgery in women with symptomatic fibroids seeking uterine preservation. In women wishing to preserve fertility, myomectomy remains the preferred treatment because of the current evidence.Practical recommendations: Patient selection should be multidisciplinary.

Because even small epidural lesions can cause significant neurological deficits through compression of the spinal cord or cauda equina, a prompt and accurate diagnosis is essential.Radiological standard procedures: Contrast-enhanced magnetic resonance imaging (MRI) is the imaging modality of first choice as it enables a reliable assessment of the tumor extent, the relationship to the spinal cord, dural sac and nerve roots as well as possible bone marrow infiltration. Characteristic imaging features, such as the origin of the mass, dorsal cortical destruction, neural foraminal widening or a dumbbell-shaped growth pattern, often enable a targeted narrowing down of the underlying tumor entity.Practical recommendations: In adults secondary epidural tumors should be primarily considered in the differential diagnosis as they account for the majority of intraspinal extradural masses. In particular, metastases, plasma cell neoplasms and lymphomas are of high clinical relevance. A systematic assessment of the anatomical location, growth pattern and possible osseous alterations are essential to narrow down the differential diagnosis and to guide appropriate further diagnostic evaluation and treatment planning.","PeriodicalId":74635,"journal":{"name":"Radiologie (Heidelberg, Germany)","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149070670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cavernous malformations typically present as small eccentric lesions with a mixed internal signal pattern and a hemosiderin rim; contrast enhancement is usually absent or only minimal. Spinal AVMs are characterized by a nidus with intra- and perimedullary flow voids; hemorrhagic stigmata may be present, and angiography demonstrates early venous drainage. Hemangioblastomas typically appear as avidly enhancing nodules, usually located superficially or subpially, often with a syrinx that is disproportionately large relative to tumor size. Magnetic resonance imaging (MRI) is the first-line imaging modality; when a shunt lesion is suspected, digital subtraction angiography (DSA) remains indispensable. The spinal dural arteriovenous fistula (SDAVF) is presented as the most important differential diagnosis; its appearance of a venous congestive myelopathy distinguishes it from the aforementioned mass lesions.","PeriodicalId":74635,"journal":{"name":"Radiologie (Heidelberg, Germany)","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148921995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
