1/74. sciatic neuropathy secondary to a uterine fibroid: a case report.

    Lesions of the sciatic nerve outside the pelvis have been well described. Lesions within the pelvis, however, are far less common. We report the case of a 55-yr-old woman with a history of chronic low back pain who presented with progressive right buttock and posterolateral right lower limb pain associated with right foot numbness and tingling. She denied any associated low back or left lower limb pain. The patient was initially treated for a probable right lumbosacral radiculopathy, without improvement. A subsequent magnetic resonance image of the lumbosacral spine revealed multilevel disc degeneration at L3-4 through L5-S1, without disc herniation or canal stenosis. A magnetic resonance image of the pelvis revealed a markedly enlarged uterus, with a large pedunculated myoma impinging on the right sciatic foramen. The patient underwent a subtotal abdominal hysterectomy, with resolution of her right lower limb pain. This case illustrates the importance of considering intrapelvic causes of sciatic neuropathy. To our knowledge, this is the first reported case of sciatic neuropathy secondary to a uterine fibroid.

2/74. Nerve root herniation secondary to lumbar puncture in the patient with lumbar canal stenosis. A case report.

    STUDY DESIGN: A very rare case of nerve root herniation secondary to lumbar puncture is reported. OBJECTIVE: To describe the characteristic clinical features of this case and to discuss a mechanism of the nerve root herniation. SUMMARY OF BACKGROUND DATA: There has been no previous report of nerve root herniation secondary to lumbar puncture. methods: A 66-year-old woman who experienced intermittent claudication as a result of sciatic pain on her right side was evaluated by radiography and magnetic resonance imaging, the results of which demonstrated central-type canal stenosis at L4-L5. The right sciatic pain was exacerbated after lumbar puncture. myelography and subsequent computed tomography showed marked stenosis of the thecal sac that was eccentric to the left, unlike the previous magnetic resonance imaging finding. RESULTS: At surgery, a herniated nerve root was found through a small rent of the dorsocentral portion of the thecal sac at L4-L5, presenting a loop with epineural bleeding. The herniated nerve root was put back into the intrathecal space, and the dural tear was repaired. CONCLUSION: Lumbar puncture can be a cause of nerve root herniation in cases of lumbar canal stenosis. The puncture should not be carried out at an area of stenosis.

3/74. diagnosis of intermittent vascular claudication in a patient with a diagnosis of sciatica.

    BACKGROUND AND PURPOSE: The purpose of this case report is to illustrate the importance of medical screening to rule out medical problems that may mimic musculoskeletal symptoms. CASE DESCRIPTION: This case report describes a woman who was referred with a diagnosis of sciatica but who had signs and symptoms consistent with vascular stenosis. The patient complained of bilateral lower-extremity weakness with her pain intensity at a minimal level in the region of the left sacroiliac joint and left buttock. She also reported numbness in her left leg after walking, sensations of cold and then heat during walking, and cramps in her right calf muscle. She did not report any leg pain. A medical screening questionnaire revealed an extensive family history of heart disease. Examination of the lumbar spine and nervous system was negative. A diminished dorsalis pedis pulse was noted on the left side. Stationary cycling in lumbar flexion reproduced the patient's complaints of lower-extremity weakness and temporarily abolished her dorsalis pedis pulse on the left side. OUTCOMES: She was referred back to her physician with a request to rule out vascular disease. The patient was subsequently diagnosed, by a vascular specialist, with a "high-grade circumferential stenosis of the distal-most aorta at its bifurcation." DISCUSSION: This case report points out the importance of a thorough history, a medical screening questionnaire, and a comprehensive examination during the evaluation process to rule out medical problems that might mimic musculoskeletal symptoms.

4/74. osteochondroma of the L-5 vertebra: a rare cause of sciatic pain. Case report.

    Solitary or multiple osteochondromas, which are benign bone tumors that usually occur in the long bones, are rarely found in the vertebral column. When present in the spine, however, they have a predilection for the cervical or upper thoracic regions. The authors present the case of a solitary osteochondroma arising from the left L-5 articular process that contributed to sciatica; complete cure was achieved following its removal. It is possible to speculate that the cartilage of secondary ossification centers can be the origin of aberrant islands of cartilaginous tissue that cause the osteochondroma to form. The more rapid the ossification process of these centers, the greater the probability that aberrant cartilage will form. Therefore, the fact that osteochondromas are more frequently located in the higher segments of the vertebral column could be explained by the different durations of the ossification processes in these centers, which increase gradually below the cervical segments.

5/74. Thoracic spondylitis mimicking idiopathic scoliosis: a case report.

    We report the case of a 12-year-old girl with thoracic spondylitis, who initially presented with a painless scoliotic deformity and was therefore misdiagnosed as having idiopathic scoliosis. Six weeks after initiation of brace therapy, increasing back pain necessitated admission. X-Ray, bone scintigraphy and magnetic resonance imaging then revealed a pathologic process in D8. To rule out a tumorous lesion, open biopsy was performed and led to the diagnosis of acute spondylitis. Treatment with oral antibiotics and bed rest led to a complete resolution of the scoliotic deformity, which clearly demonstrated that it was secondary to spondylitis. After 2 years, the girl is persistently well and free of pain. This unusual presentation of spondylitis delayed correct diagnosis and therefore specific treatment in the case of this 12-year-old girl.

6/74. Fibrous adhesive entrapment of lumbosacral nerve roots as a cause of sciatica.

    STUDY DESIGN: Report of seven patients with fibrous adhesive entrapment of lumbosacral nerve roots as a cause of sciatica, whose radiographic findings were negative and who experienced relief from sciatica immediately after the entrapment was released. OBJECTIVES: To describe a new clinical entity of fibrous adhesive entrapment of lumbosacral nerve roots with negative radiographic findings. SETTING: Orthopaedic department, japan. methods: Clinical evaluation and post-operative outcome in seven patients with entrapment of lumbosacral nerve roots because of fibrous adhesion confirmed intraoperatively. RESULTS: Radiographic examinations by magnetic resonance imaging (MRI), myelography, and computed tomographic (CT) myelography demonstrated neither disc herniations nor spinal stenosis in all seven patients, and differential nerve root block was effective for relieving sciatica and low back pain. We confirmed, intraoperatively, entrapment of the nerve root by fibrous adhesion, and all seven patients were relieved from sciatica and low back pain postoperatively. CONCLUSION: This study presented seven patients with sciatica caused by fibrous adhesive entrapment of lumbosacral nerve roots who underwent decompression and release of fibrous adhesion. Radiographic examinations, such as MRI, myelography and CT myelography, showed no compressive shadows and also differential nerve root block was effective for its diagnosis. This study seems to be the first report of patients with entrapment of lumbosacral nerve roots caused by fibrous adhesion, whose radiographic findings were negative.

7/74. The centralization phenomenon in chiropractic spinal manipulation of discogenic low back pain and sciatica.

    OBJECTIVE: To describe 3 cases of discogenic low back pain and leg pain in which the centralization phenomenon was used in determining chiropractic treatment and prognosis. CLINICAL FEATURES: Three men with low back pain and sciatica, positive straight leg raise, mild neurologic deficits, and evidence of discogenic disease requested chiropractic treatment. Two of the patients exhibited centralization of pain on provocation testing; the third did not. INTERVENTION AND OUTCOME: All patients were treated with chiropractic side-posture manipulation, ancillary therapies, and pain medications. The 2 subjects whose pain centralized had excellent outcomes to treatment. The one whose pain did not centralize had a poor outcome and eventually required surgery. CONCLUSION: Assessment of the centralization phenomenon provided valuable diagnostic and prognostic information regarding chiropractic side-posture manipulation in this case series.

9/74. Metastatic meningioma in the sacrum: a case report.

    STUDY DESIGN: This report describes a 51-year-old woman with a sacral metastatic meningioma that originated from an intracranial meningioma. OBJECTIVES: To describe an unusual presentation of a metastatic meningioma in the sacrum. SUMMARY OF BACKGROUND DATA: Extracranial metastases of meningioma are very rare. The phenomenon of metastasis may have more to do with the ability to invade the wall of a blood vessel than with the mitotic activity of a tumor. Therefore, metastases of the meningioma can occur even with a benign histologic picture in the original intracranial meningioma. methods: A 51-year-old woman had experienced low back pain and sciatica of the left leg for several months. Plain radiographs of the lumbosacral spine showed an osteolytic lesion with an irregular margin that occupied the left side of the sacrum. magnetic resonance imaging revealed a soft mass invading the left sacrum, ilium, and presacral space. RESULTS: Surgical removal of the sacral tumor via an anterior-posterior-anterior approach was done. Histopathologic examination revealed a metastatic meningioma with a meningotheliomatous histologic composition. Sixteen months after excision of the metastatic sacral lesion, the patient was ambulating freely and experiencing mild constipation and urine retention. CONCLUSIONS: In this case of metastatic meningioma in the sacrum, which is the first such report to the authors' best knowledge, total excision of the tumor was successful.

10/74. Swelling of the leg, deep venous thrombosis and the piriformis syndrome.

    BACKGROUND: The piriformis syndrome, which was first described 60 years ago, is a well recognized cause of sciatica, leg pain and low back pain, due to the entrapment of the sciatic nerve in the piriformis and other rotator muscles. Very few complications relating to this syndrome have been described. AIMS: To discuss how the piriformis syndrome may cause venous engorgement in the lower limb, and how the piriformis syndrome should be included as a possible cause of acute deep venous thrombosis in a not initially swollen leg. Both complications can occur independently. methods: Two cases of swelling of the leg and acute deep venous thrombosis independently associated with the piriformis syndrome are presented. CONCLUSIONS: Swelling of the leg and deep venous thrombosis are possible complications of the piriformis syndrome that occur due to entrapment of nerves and vessels within the leg, secondary to a severe spasm and hypertrophy of the piriformis and other rotator muscles.
