The classic CT appearance of a hemangioma is a well-circumscribed lesion with a sharp transition zone and sclerotic margin within the vertebral body; the lesion is hypoattenuating with a “polka-dot” pattern (due to a cross-section of reinforced trabeculae) or “corduroy” appearance (due to rarefaction with vertical striations) on axial images a b s t r a c t. Atypical hemangiomas of the spine can mimic metastaticlesions on magnetic resonance imaging,thereforemakingthis distinction isadiagnostic challenge. These are usually an incidental finding found on radiological imaging of the body and spine. In particular, magnetic resonance features are not well established. Usually asymptomatic and identified in middle-aged patients. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors. Vertebral hemangiomas (VH) are an incidental and relatively common radiological finding and a benign tumor of vascular origin. Less than 1% of vertebral hemangiomas produce symptoms owing to collapse (pathologic fracture) or cord compression . Fox MW, Onofrio BM. Numerous radiological signs for VHs have been described, but compressive VHs frequently have atypical features. Ross JS, Masaryk TJ, Modic MT, Carter JR, Mapstone T, Dengel FH. Previous medical history is notable for L1 and L2 vertebral bony lesions identified on prior outside hospital MRI of the lumbar spine imaging, which were biopsy proven hemangiomas (), and were previously treated with radiation therapy. Pregnancy is a recognized risk factor coinciding with the development of a rapid onset of symptoms from these normally asymptomatic lesions. It can mimic malignancy on imaging, particularly as it regularly has an extrasosseous soft tissue component. 2A–G) and metastatic bony lesions (Fig. Case of the Week 587 on award-winning, radiologic teaching site for medical students and those starting out in radiology focusing on chest, GI, cardiac and musculoskeletal diseases containing over 300 PowerPoint lectures, quizzes, hand-out notes, interactive material, most commons lists and pictorial differential diagnoses All studies on vertebral augmentation procedures were performed primarily on metastatic lesions and/or multiple myeloma (Tables 1, 2), except 1 study. J Radiol Case Rep. 2011; 5(10): 7–13. (1) Department of Radiology, Seoul National University College of Medicine, Seoul National University Bundang Hospital, Seongnam, South Korea. 2019;103(1):38. They are asymptomatic, incidental findings in the vast majority of patients; however, in rare cases, they can expand to cause neural compression. PMID:3628764 7. Vertebral hemangiomas are benign lesions accounting for 2 to 3% of all spinal tumors. Vertebral haemangiomas (VHs) are well described lesions of the spine which comprise almost 12% of all benign tumours affecting the general population. Vertebral Metastases Atypical Hemangioma PET/CT Scan. Most of them are asymptomatic and the diagnosis is usually made based solely on imaging. 27.2.2 Imaging Analysis. We present the case of a 50-year-old male with consistent back pain, not resolving with conservative treatment. 6.1 Angiolipoma. Correct preoperative diagnosis is useful both for operative planning (since compressive VHs are extremely vascular lesions) and to allow preoperative embolisation. The most common places are in … In a review article, low T1 signal intensity was found to be present in 48 % of 25 cases of compressive lesions, and in smaller-sample series, this percentage is often even higher [].In the same article reviewing the imaging findings of compressive vertebral hemangiomas, the polka dot sign … A hemangioma is a noncancerous, slow-growing tumor, made of newly formed blood vessels. Multiple hemangiomas were seen in 33% of cases. Thorough examination with computerized tomography and magnetic resonance imaging revealed a hemangioma extending to the posterior third of the vertebral body, compressing the … Else­ JBR–BTR, 2010, 93: 1-3. 9-5 Legend continued on page 129.. Between 1975 and 1996, 14 patients (11 females, 3 males) with vertebral hemangioma received treatment with radiotherapy. Six features were seen significantly more often in those compressing the cord: location between T-3 and T-9, involvement of the entire vertebral body, extension to the neural … 2002 May 7 5 citations Vertebral hemangioma presenting as a cold defect on bone scintigraphy. Plain radiographs reveal a “corduroy cloth” appearance due to the longitudinally oriented trabecular capillary network. Rare But Interesting Spinal Tumors (in Alphabetical Order) , Joon Woo Lee1 and Eugene Lee2. Aggressive hemangioma can occur at any age, with peak prevalence in young adults, and is localized preferentially in the thoracic spine. Brain 98:71–80 PubMed CrossRef Google Scholar. Vertebral hemangiomas are relatively common, occurring in 11% of patients in a large autopsy series . The postoperative and follow-up imaging showed that the implant was in perfect position, and no recurrence occurred in all patients. They represent approximately 1% of spinal hemangiomas and are usually symptomatic 1. Presentation. Our purpose was to analyze various MR imaging features of a spinal epidural hemangioma with histopathologic correlation. Because of the complex anatomy of the vertebrae, CT is more useful than conventional radiography for evaluating lesion location and analyzing bone destruction and condensation. Pregnancy is related to the worsening of aggressive VHs. https://academic.oup.com/neurosurgery/article-abstract/39/5/1054/2812321 Imaging. Vertebral hemangiomas (VH) are benign vasoformative neoplasms of endothelial cells that grow within marrow spaces in the bone and encase bony trabeculae. Fig. Vertebral hemangiomas are diagnosed by MR (magnetic resonance) imaging and/or CT (computed tomography, also known as a CAT scan). 27.1 ). Thirteen patients had a history of back pain or lumbago and 2 patients had neurological symptoms such as sensory impairment or paraplegia. If the imaging tests confirm that the individual is with spinal hemangiomas, the doctor might order an angiogram, a specialized radiographic study, to check the blood supply to the tumor. may be multi-focal. may be asymptomatic. However, although rare, some hemangiomas with atypical imaging features (aggressive hemangiomas) can pose a diagnostic challenge. Hemangioma Symptoms and Diagnosis Hemangioma diagnosis. Vertebral hemangioma at T11.. Lumbar spine degenerative changes as multilevel endplate sclerosis and marginal osteophyte formation. Symptoms. Three of four vertebral hemangioma that were 3 cm or larger showed abnormally increased or decreased uptake on SPECT images. Vertebral Hemangioma. It can occur at any age, but mostly after the fourth or fifth decade of life. 74. If a hemangioma is suspected, the doctor will order an x-ray to check for a specific pattern on the bone, called a trabecular pattern. Atypical hemangioma. Linear areas of decreased signal are seen within the lesion on the T2WI. Vertebral hemangiomas are common lesions and usually considered benign. AB - Vertebral hemangiomas are … MATERIALS AND METHODS: Eleven patients with paraplegia (n = 6) or radiculopathy (n = 5) due to vertebral hemangioma were treated by means of injecting ethanol (5–50 mL) directly into the lesion with computed tomographic (CT) guidance. Vertebral hemangiomas: MR imaging. Around 75 percent of hemangiomas in bones are found in the spine or skull, according to the x-ray text, "Essentials of Skeletal Radiology." View larger version (116K) Fig. 1987 Oct;165:165-169. Radiographs. There is a focal lesion within the T12 vertebral body that is high in signal on both T1WIs and T2WIs ( Fig. Most of the lesions are asymptomatic, found incidentally on radiological imaging 1, 2.The active and symptomatic lesions are rare and can lead to serious neurological deficits if untreated 3, 4.We present a patient with spinal cord compression secondary to epidural extension of an active vertebral hemangioma, and discuss …
