Rare Tumors , 2009, DOI: 10.4081/rt.2009.e10
Abstract: Capillary hemangiomas are benign vascular neoplasms. When associated with the spine, these growths frequently involve the vertebral body, but rarely have they been reported to occur as intradural lesions, while even more rarely occurring in a true intramedullary location. We report a rare case of an intrame-dullary capillary hemangioma of the thoracic spinal cord and a review of the literature.

Abstract: Cavernous hemangiomas can arise in any region of the body, including the central nervous system. Spinal cavernous hemangiomas account for 5% - 12% of all cases of vertebral vascular malformation. Most of these are of vertebral origin, and cases that are non-vertebral in origin are rare. We encountered a patient with a relatively rare spinal epidural cavernous hemangioma of the thoracic spine that was non-vertebral in origin. The patient was a 63-year-old man. He had become aware of bilateral leg pain and numbness about 2 months earlier, and gait disturbance appeared gradually thereafter. On MRI, a lesion showing iso-intensity on T1-weighted imaging and high intensity on T2-weighted imaging was detected at the 7th thoracic vertebra. On gadolinium contrast-imaging, the lesion was found to be a homogenously-enhanced dumbbell-shaped extradural spinal neoplasm protruding from the left 7th/8th thoracic intervertebral foramen. A neurogenic tumor was suspected based on myelography and MRI findings, and complete tumorectomy was performed, which improved the lower limb symptoms and gait disturbance. The histopathological diagnosis was cavernous hemangioma. Epidural hemangiomas arise from the vertebra in many cases, and pure spinal epidural cavernous hemangiomas are rare. It is difficult to make a preoperative diagnosis because there are no specific imaging findings that can differentiate these tumors. It may be important to consider this disease before surgery in the differential diagnosis of epidural tumors.

Journal of Cancer Research and Therapeutics , 2010,
Abstract: Background: Vertebrae are the second commonest site among skeletal locations affected by hemangioma, but only about one per cent becomes symptomatic throughout the life. Though surgery, intra vertebral injection of various sclerosing agents have been tried in treating this benign process, no general consensus regarding management has been reached. Radiotherapy is emerging as a low cost, simple, non-invasive but very effective modality of treatment of symptomatic vertebral hemangioma. Aim: This study aims to find out the role of external beam radiotherapy in alleviating the symptoms of symptomatic vertebral hemangiomas without compromising the quality of life. Materials and Methods: Seven consecutive patients with symptomatic vertebral hemangioma were treated with a fixed dose of external beam radiotherapy; and muscle power was assessed before, after treatment and during follow-up. Results: All patients showed improvement of muscle power, which increased with the passage of time. Pain relief with improvement of quality of life was obtained in all the patients. Conclusion: Effect of radiotherapy on vertebral hemangioma is dose-dependent and the dose limiting factor is the spinal cord tolerance. In the present era of IMRT, greater dose can be delivered to the parts of vertebra affected by the hemangioma without compromising the spinal cord tolerance and expected to give better results.

Journal of Medical Sciences , 2004,
Abstract: The present experimental investigation was aimed to observe structural changes in thoracic segments of the spinal cord in developing fetus of diabetic mouse mother. A total of 124 adult mice (100 females and 24 males) of ICR strain were used. Diabetes was induced in 55 female mice by two intraperitoneal injections of streptozotocin. Animals with blood glucose level > 200 mg dL-1 were considered diabetic and mated with adult male mice. The other 45 female mice served as controls without any diabetes induction. Successful mating in treated and control animals was indicated by the presence of vaginal plug and this day was considered as gestational day (GD) 0. Pregnancy was terminated on GD 14, 16, 18 and 20 (day of delivery). Foetuses and pups were fixed in 10% formaldehyde for light microscopy study. The light microscopic observation demonstrated asymmetry of the two-halves of the spinal cord at thoracic segments of the spinal cord. Shrunken or eroded dorsal funiculi and dorsal horn represented the most frequent defect in the foetus/pup of GD 16 (23 in number), GD 18 (21 in number) and GD 20 (26 in number). In addition, the white and grey matters on the lateral and dorsal sides are much reduced in size or disappeared. Imperfect growth and protrusion of spinal cord were also observed. In some cases, a portion of the spinal cord has protruded beyond the vertebral laminae showing a condition called meningomyelocele. Irregularity and dilatation of the central canal were also noticed. These changes were not present in the control samples. The findings in the present investigation implicated that the central nervous system is subjected to structural changes in the developing foetus when exposed to diabetic milieu. The results are supportive of the previous clinical studies that indicated neurobehavioural and habituation disturbances in the offspring of diabetic mothers.

Abstract: synovial sarcoma is an uncommon malignant soft tissue neoplasm, occurring primarily in adolescents and young adults. it is prevalent in the periarticular soft tissues near large joints of the extremities and rarely involves the trunk. metastases are not uncommon and usually involve the lungs; metastasis to the thoracic spine is rare. we report the case of a 47-year-old man with a history of synovial sarcoma of the lower back, with subsequent metastases to the lung, penis, and perineum (all previously resected), presenting with a 3-month history of low back pain and lower extremity paresthesias. magnetic resonance imaging (mri) demonstrated multiple lesions involving multiple contiguous vertebral bodies, with the mass at t12 compressing the spinal cord. the patient underwent t11-t12 laminectomy, transpedicular decompression, tumor debulking, and posterior fixation and fusion. the patient died six months later due to disease progression. although not curative, decompression and stabilization of the spine are often necessary in patients who present spinal cord compression.

Abstract: We report the case of a 28-year-old Iraqi man who was referred to our radiology department with lower limb paraplegia secondary to a gunshot wound. We performed 64-slice computerized tomography with two-dimensional and three-dimensional reconstruction of the thoracolumbar spine. On the two-dimensional and three-dimensional reconstructed axial images of the thoracolumbar spine, an intra-canalicular bullet nucleus was found at the mid-spinal cord at the T8 level, with no evidence of vertebral bone destruction.To the best of our knowledge, there is only one previous report in the literature describing a case of a bullet nucleus lodged into the inferior epidural spinal canal without destruction of the vertebral bone. With the rise of violence worldwide the incidence of gunshot injuries continues to increase, and, thus, it is essential for radiologists to have a clear understanding of gunshot injuries and the findings on radiographic images.Gunshot wounds to the spine are potentially devastating injuries that account for approximately 13% to 17% of all spinal cord injuries every year [1]. The thoracic spine is the most commonly affected region, but gunshot injuries involving the cervical spine are the most devastating of all injuries; such injuries result in the most severe functional impairments [2]. Spinal cord injuries inflicted by firearms usually result in complete paraplegia [3]. This neurological outcome (paraplegia) results from direct trauma brought about by compression of the spinal cord by the bullet nucleus, bone fragments, and sometimes disc particles [4].To the best of our knowledge, there is only one previous report in the literature [5] describing a case of a foreign body lodged into the vertebral canal after a gunshot injury without any accompanying destruction of bony tissues. Our case report is the second such report. The patient in the first case reported presented without neurological deficit, but our patient presented with paraplegia.A 28-year-old I

Abstract: A 50-year-old woman presented with mid-thoracic backache and progressive, spastic, paraparesis for 3 months. Magnetic resonance imaging revealed an epidural mass without bone lesion at the level of thoracic vertebrae (T7, T8 and T9). The mass had a paraspinal invasion. The spinal cord was compressed ventrally. The lesion was totally excised through an anterolateral transthoracic approach. Histopathological examination revealed a cavernous hemangioma. The patient improved dramatically after the excision of the lesion. We report this case for its rarity.

Ciência Rural , 1997, DOI: 10.1590/S0103-84781997000300024
Abstract: a case compression of the spinal cord in a horse by a tumor located in the vertebra is described. a 10-year-old gelding was euthanized after being found recumbent with hind limb paresis of unknown duration. at necropsy an hemangiosarcoma was detected in the vertebral body of t3. the tumoral mass invaded upwards through the bone tissue of the vertebral body into the vertebral canal, compressing the spinal cord and causing wallerian degeneration at t1-3 levels of the cord.
Incidence of Vertebral Hemangioma on Spinal Magnetic Resonance Imaging in Northern Iran
M. Barzin,I. Maleki
Pakistan Journal of Biological Sciences , 2009,
Abstract: The incidence of vertebral hemangiomas as the most common benign spinal neoplasms has been differently reported from 10 to 27% based on autopsy series, plain X-rays and MRI reviews. In this study, we reviewed consecutive 782 standard spinal MRI with axial and sagital T1 weighted and T2 weighted images looking for hemangiomas. In this study, the incidence of hemangioma was 26.9%, more common in females (30%) than males (23%), in older age group and in lumbar spine. Most hemangiomas (65%) were less than 10 mm in diameter. Multiple hemangiomas were seen in 33% of cases. The results of this study are similar to another Mediterranean study reported based on MRI findings, but differ from other reports using X-ray or autopsy as diagnostic tool, suggesting the influence of either the race or the sensitivity of the diagnostic tool on the incidence of vertebral hemangioma.
