1/243. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/243. Vertebra plana of the lumbar spine caused by an aneurysmal bone cyst: a case report.The patient was a 15-year-old girl who had a lesion of the fourth lumbar vertebra. Plain radiographs suggested vertebra plana, with complete collapse of the body of the fourth lumbar vertebra and no involvement of the intervertebral disk spaces. The presumptive diagnosis was eosinophilic granuloma. Progressive neurologic symptoms required surgical excision of the lesion, decompression, and fusion. Histopathologic examination of the operative specimen confirmed the diagnosis of an aneurysmal bone cyst.- - - - - - - - - - ranking = 0.625keywords = cyst (Clic here for more details about this article) |
3/243. Long-term follow-up of skeletal dysplasia in thalassaemia major.We report skeletal changes due to deferoxamine (DF) in 15/29 patients with transfusion-dependent thalassaemia major (TM), followed longitudinally for growth assessment. Clinically the earliest signs were decline in height and/or sitting height growth rate, leg and back pain with restricted movement and limb deformity. Radiologically metaphyseal and spinal changes were seen in 5 subjects and vertebral lesions alone in 10. The metaphyseal changes were mild, moderate or severe and affected all long bones, but were most pronounced at wrists and knees. They progressed from widening of the growth plate and defects of metaphyseal margins to appearance of radiolucent pseudocystic areas and, in severe cases, of cupped, rickets-like metaphyses. The spinal changes proceeded from osseous defects of ventral upper and lower edges of vertebrae and biconvex contours of end-plates to platyspondyly with decreased vertebral body height. After DF dose reduction, metaphyseal changes regressed in 2 patients, while they progressed in 3, requiring corrective surgery for severe valgus knee. Spinal abnormalities either remained unchanged or progressed. Final height was very short in patients with spondylometaphyseal lesions, short and disproportionate in patients with only spinal involvement.- - - - - - - - - - ranking = 0.125keywords = cyst (Clic here for more details about this article) |
4/243. Intraspinal epidermoid cyst occurring 15 years after lipomyelomeningocele repair. Case report.The authors report the case of a spinal epidermoid cyst that developed in a patient who had undergone surgery for lipomyelomeningocele repair 15 years earlier. The patient presented with symptoms of retethering. magnetic resonance imaging revealed a cystic intraspinal mass that extended from L-2 to L-5. The mass proved to be an epidermoid cyst. Spinal epidermoid cysts can cause retethering after a repair of lipomyelomeningocele, and the risk of this development can be present for decades.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
5/243. Intraspinal extradural cysts communicating with adjacent herniated disks: imaging characteristics and possible pathogenesis.We report two cases of intraspinal extradural cysts communicating with an adjacent herniated disk that we term "disk cysts." These cysts were well defined and homogeneous, and were present in the ventrolateral extradural space adjacent to a lumbar herniated disk. They had rim enhancement on contrast-enhanced MR images, and communication with a herniated disk was revealed by diskography.- - - - - - - - - - ranking = 0.875keywords = cyst (Clic here for more details about this article) |
6/243. Immunochemical and molecular characterization of vertebral hydatid fluid.This study describes a 42-year-old male born in tunisia, who presented with vertebral hydatidosis which was initially misdiagnosed as Pott's disease. The correct diagnosis was finally made utilizing CT and MRI imaging and confirmation of the diagnosis was made possible by molecular and immunochemical characterization of the content of vertebral cyst fluid.- - - - - - - - - - ranking = 0.125keywords = cyst (Clic here for more details about this article) |
7/243. Vertebral unilocular hydatidosis in a shepherd and his wife.This paper reports vertebral unilocular hydatid cysts in a shepherd and his wife in Sharkia Governorate. diagnosis was based on parasitological examination of the surgically removed cysts. albendazole was given as postoperative treatment. MRI six months after treatment, showed no recurrence and mild clinical improvement.- - - - - - - - - - ranking = 0.25keywords = cyst (Clic here for more details about this article) |
8/243. Lumbar spinal synovial cyst presenting with neurological deficit. A case report and review of the literature.A spinal synovial cyst is a rare condition. We reported a case of lumbar spinal synovial cyst presenting neurological deficit. A 78-year-old woman was admitted to our hospital with the low back pain radiating to the left buttock. A myelography with computed tomography and magnetic resonance imaging revealed an extradural cystic lesion at the L5 and S1 level. At the time of surgery, a standard posterior approach was used to expose the posterior elements from L5 to S1. An en bloc laminectomy and total removal of the cyst was performed at the L5 to S1 level. The postoperative recovery was uneventful except for a slight pain in the left leg which persisted for some time.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
9/243. Treatment of an aneurysmal bone cyst of the spine by radionuclide ablation.We report the nonoperative treatment of a recurrent, multilevel spinal aneurysmal bone cyst by injection of 32P chromic phosphate colloid into the cyst. The patient was then followed up with serial CT examinations, which showed stabilization and progressive ossification within the lesion. The rationale, alternatives, and possible contraindications to radionuclide ablation of spinal aneurysmal bone cysts are discussed.- - - - - - - - - - ranking = 0.875keywords = cyst (Clic here for more details about this article) |
10/243. Intramedullary spinal epidermoid cyst.Intramedullary epidermoid cysts of the spinal cord are rare tumours, especially those not associated with spinal dysraphism. Around 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient the tumour was located at D4 vertebral level, while in other within the conus medullaris. The clinical features, MR imaging characteristics and surgical treatment of such rare intramedullary benign tumours are discussed, and the relevant literature reviewed.- - - - - - - - - - ranking = 0.75keywords = cyst (Clic here for more details about this article) |
