1/31. Giant cauda equina schwannoma. A case report.STUDY DESIGN: Case report. OBJECTIVES: To present a rare case of a giant schwannoma of the cauda equina. SUMMARY OF BACKGROUND DATA: Giant spinal schwannoma of the cauda equina, which involves many nerve roots, is rare and there is usually no ossification in the schwannoma. It is unknown whether or not complete excision is preferable if the tumor is located in the lumbar lesion. methods: A 57-year-old woman had a 10-year history of low back pain. Scalloping of the posterior surface of the vertebral bodies from L3 to the sacrum was found. magnetic resonance imaging disclosed a giant cauda equina tumor with multiple cysts. Central ossification revealed by computed tomography and an unusual myelogram made the preoperative diagnosis difficult. RESULTS: The patient underwent incomplete removal of the tumor, decompression of cysts, and spinal reconstruction. The tumor was proved to be a schwannoma. The postoperative course was uneventful and she has been almost free from low back pain for 3 years and 4 months. CONCLUSIONS: Giant schwannoma in the lumbar spine region is usually excised incompletely, because complete removal had the risk of sacrificing many nerve roots. In spite of the incomplete removal of the tumor, the risk of recurrence is low.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/31. 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 = 4keywords = cyst (Clic here for more details about this article) |
3/31. Lumbar intraspinal synovial cyst containing gas as a cause for low-back pain.OBJECTIVE: To discuss intraspinal synovial cysts caused by degenerative changes involving the posterior articular facets in the lumbar spine and to provide differential considerations for patients with low-back pain. Clinical Features: A 70-year-old man with low-back and gluteal pain demonstrating eventual progression of radiating pain into the left thigh, calf, ankle, and foot over a 5-month period. Radiographs of the lumbar spine revealed mild degenerative disk disease at L5-S1 with associated vacuum phenomena of the L5 disk. Degenerative osteophytes were present at L3, L4, and L5. Moderate posterior joint arthrosis was evident at L4-L5 and L5-S1. Computed tomography and magnetic resonance imaging studies revealed an intraspinal gas-containing synovial cyst at the left lateral aspect of the central canal at the level of the left L4-L5 facet articulation. Intervention and Outcome: The patient underwent surgical excision of the synovial cyst with remission of symptoms. CONCLUSION: Gas-containing intraspinal synovial cysts can be a significant finding and a causative factor in patients with low-back pain and pain radiating into the lower extremities. Both computed tomography and magnetic resonance imaging are important in defining intraspinal synovial cysts as a cause of back pain in patients whose low-back pain does not respond to chiropractic care.- - - - - - - - - - ranking = 4.5keywords = cyst (Clic here for more details about this article) |
4/31. Haemorrhagic lumbar synovial cyst. A cause of acute radiculopathy.A total of 254 cases of synovial cysts of the spine have been reported in the English literature, but only eight have been associated with haemorrhage. We describe a 55-year-old man with acute radiculopathy resulting from haemorrhage involving a synovial cyst at a lumbar facet joint. Traumatic factors could have caused bleeding around or into the synovial cyst. Treatment by resection of the cyst and evacuation of the haematoma led to complete neurological recovery.- - - - - - - - - - ranking = 4keywords = cyst (Clic here for more details about this article) |
5/31. synovial cyst of lumbar spine presenting as disc disease: a case report and review of literature.Synovial cysts most commonly involve the joints of the extremities. These cysts are rarely found in the spinal canal or the vertebral facet joints. However, if manifested as such, they can pose serious diagnostic and therapeutic problems due to the presentation, which most often resembles nerve root or spinal cord compression. Acute low back pain and radiculopathy are often attributed to a herniated nucleus pulposus. This paper presents a case of synovial cyst in a 62-year-old woman with a 2-year history of refractory low back pain with distal radiation. A facet joint cyst was encountered upon neuroimaging, resulting in excision of the cyst. In this report, we discuss the differential diagnosis of synovial cysts, the role of computed tomography and magnetic resonance imaging in the diagnosis, and treatment options for this uncommon entity.- - - - - - - - - - ranking = 5keywords = cyst (Clic here for more details about this article) |
6/31. Fibrous dysplasia of both alae of the sacrum.A case of monostotic fibrous dysplasia involving both alae of the sacrum is reported. Only 2 cases of monostotic sacral involvement were published previously. The lesion was detected in a 42-year-old man suffering from lumbosacral pain after minimal trauma. Radiographic studies revealed cystic images on both alae of the sacrum, with internal condensations and some liquid contents. A trephine biopsy did not produce enough diagnostic data, and a posterior surgical approach was elected. curettage and refilling with allograft were performed. The pathologic anatomy study diagnosed a fibrous dysplasia. Two years after surgery, the patient was asymptomatic.- - - - - - - - - - ranking = 0.5keywords = cyst (Clic here for more details about this article) |

8/31. Lumbosacral pain in an athlete.This report presents a case of a stress fracture in the sacrum. The diagnosis of a stress fracture in the sacrum is an uncommon localization and has been reported infrequently in the English literature. association of this type of stress fracture with a pneumatocyst has not previously been reported.- - - - - - - - - - ranking = 0.5keywords = cyst (Clic here for more details about this article) |
9/31. Sacral meningeal cyst associated with valve-like mechanism--case report.A 58-year-old woman presented with low back pain radiating to the lower extremities. magnetic resonance imaging revealed a cystic lesion in the sacrum compressing the nerve roots. At operation, a valve-like communication was found between the subarachnoid space and the cyst cavity in the vicinity of the sacral nerve root. The communication was obliterated with a purse-string suture and reinforced with a free muscle graft. Postoperatively, she reported improvement of the pain. Valve-like communication between the cyst cavity and subarachnoid space can cause enlargement of spinal meningeal cyst, and could also explain enlargement of sacral meningeal cyst. Surgical obliteration of the communication rather than the cyst resection is more important for sacral meningeal cyst.- - - - - - - - - - ranking = 5.5keywords = cyst (Clic here for more details about this article) |
10/31. Sacral extradural arachnoid cyst: a rare cause of low back and perineal pain.Sacral extradural arachnoid cysts are rare. The clinical and radiological features of this condition are characteristic. One such rare case with low back and perineal pain is presented and the literature is reviewed. This patient presented with pain in the low back and perineal region, which was aggravated by standing, walking and straining. The patient also had numbness in both lower limbs, precipitated by standing and walking. Both the symptoms were relieved by lying down. magnetic resonance imaging (MRI) revealed a sacral extradural arachnoid cyst. Sacral laminectomy with opening of the arachnoid cyst and ligation of the fistulous tract was done. Postoperatively, there was complete clinical recovery. Though rare, this entity should be considered in the differential diagnosis of low back and perineal pain. Surgical treatment is curative.- - - - - - - - - - ranking = 3.5keywords = cyst (Clic here for more details about this article) |
