Objectives:To study 1)the efficacy of transforaminal percutaneous endoscopic lumbar discectomy in lumbar disc herniations.2) limitations and advantages of the surgical procedure. 3)morbidity and complications associated with the procedure.Materials and Methods:This study was carried out on 120 patients who had single level herniated disc Pre-operative assessment of VAS and MSS scoring systems were documented one day prior to surgery. Post operative results were determined by MacNab criteria and by modified Suezawa and Schreiber clinical scoring system (MSS score).Results:Maximum patients were in the age group of 31 to 40 years and 83.43% of the patients were males. 80% patients had lumbar disc herniation at L4-L5 level, The mean operative time of endoscopic discectomy was 52.28 minutes and the mean hospital stay was 2.1days.8 cases of L5-S I were abandoned due to high iliac bone and hence their disc could not be accessed. Out of 112 patients who underwent operation, 2 patients developed discitis and 1 was found to have dysesthesia. Also recurrent prolapsed intervertebral disc was seen in 6 cases The mean preoperative and 6 months follow-up VAS score was 8.4 and 1.89 respectively. Mean preoperative and 6 months follow-up Modified Suezawa And Schreiber Clinical Scoring System(MSS Score) was 3.47 and 7.92 respectively. MSS score showed excellent and good outcome in 82.12% patients and Modified Macnab Criteria showed excellent and good outcome in 89.3% patients at 6months follow-up.Conclusion:TPELD can be a reasonable alternative to conventional microscopic discectomy for the treatment of patients with LDH. We also conclude that TPELD is not an effective procedure for L5-S 1 disc and an open procedure should be opted for better outcomes.
We report two cases with giant intramedullary epidermoid cysts in the thoracolumbosacral and lumbosacral regions with varied presentations. Magnetic resonance (MR) imaging of the thoraco lumbar spine in case 1revealed an intramedullary elongated mass extending from T10 to S2 level causing significant widening of the spinal canal while MR imaging of lumbosacral spine in case 2 showed straightening of the lumbar spine and spina bifida at L5 level with conus at L3 and a lobulated long segment intramedullary solid cystic lesion extending from L2 to S2 veterbrae. The lesion was surgically resected and the pathology revealed an epidermoid cyst. Epidermoid cysts of the spinal cord are rare tumours in the adult population which may be congenital or acquired. Symptoms arising from epidermoid cysts vary with the level of involvement. The treatment of epidermoid cysts is surgical and if possible, complete removal is the goal.
Aneurysmal bone cysts (ABCs) are benign bone lesions mainly occurring at the metaphyseal end of long bones and are a rarity in the calvarium. The reported incidence of this lesion in the skull is 1% of all the ABC. It is a benign condition that may extend intracranially. We report here a case of a 3½-year-old male child who presented with a bony hard, painless, and gradually enlarging swelling over his right temporal region. Radiological investigations and histology revealed that the lesion was an ABC. A total surgical excision was achieved despite its intracranial extension along with the involvement of dura. Prognosis is excellent with total removal as a total surgical removal of the lesion is considered curative. The rarity of the lesion along with a good surgical result despite an intracranial extension with dural involvement prompted this report.
Background:Ventriculoperitoneal (VP) shunt is commonly used in the treatment of hydrocephalus. Migration and extrusion of the distal end of the VP shunt are relatively rarely occurring complications.Aim:To retrospectively analyze patients with extrusion of the abdominal end of ventriculoperitoneal shunts and evaluate the possible etiology and outcome.Settings and Design:All patients presenting with extrusion of lower end of the shunt were included. The variables collected were age, sex, site of extrusion, time duration of extrusion, presence of local infection, meningitis, shunt dependency, and treatment received. Contrast-enhanced computed tomography of brain was carried out in all patients to rule out retrograde migration of infection in the cranial cavity.Materials and Methods:Eight patients of abnormal migration and extrusion of lower end of VP shunt were included.Results:The distal end of VP shunt was extruded from the anus (n = 3), vagina (n = 2), and anterior abdominal wall (n = 3). In five of these patients, shunt catheter was draining cerebrospinal fluid (CSF), the children were afebrile and CSF was sterile. In three children with extrusion of the shunt through the abdominal wall, the shunt tract was infected. Two of these patients had abscess in the shunt tract, which required incision and drainage. Both these patients had meningitis with a growth of Streptococcus species from CSF. Seven patients required further CSF diversion such as endoscopic third ventriculostomy (n = 3) or placement of VP shunt (n = 4).Conclusion:Distal tip migration of VP shunt may prove to have potentially serious complications such as meningitis. A prompt and aggressive protocol of management is recommended.
Spinal schwannomas are slow-growing benign tumors arising from the nerves. In the spinal cord, they arise most commonly from cervical and lumbar levels. They are mostly intradural extramedullary (IDEM) accounting for 30% of intradural tumors showing a female preponderance. They are seen occurring between 25 and 50 years of age. Most of these cases show acute presentation as hemorrhage within the tumor with weakness. This is a rare presentation by itself reported by only 12 cases world over. It is even rarer to see them show chronic presentation. We are reporting one such case of a 61-year-old female who presented to us with chronic low backache for 3 years with radicular symptoms in the bilateral lower limbs following a fall on her back. Magnetic resonance imaging was done which showed a well-defined IDEM lesion from L3 to L5 vertebral level which was isointense on T1 and hyperintense on T2 with a peripheral rim and short inversion time inversion-recovery showed fluid-fluid level within. Gradient-recalled echo showed blooming with no suppression on fat-sat and no diffusion restriction. A computed tomography angiography was done which ruled out vascular malformation. Intraoperatively, a large feeding vessel with a tumor was visualized after laminectomy was done for the corresponding levels. Postoperatively, the patient showed a significant decrease in radicular symptoms and was discharged after 2 weeks with an uneventful postoperative period. HPE of the lesion showed sheets of fascicles of elongated spindle cells arranged in loose myxoid matrix with hyperchromatic nuclei and scanty hemorrhage and lymphocytic infiltrates suggestive of schwannoma with myxoid degeneration. Immunohistochemistry also confirmed a diagnosis of schwannoma. From this case, it is seen that the diagnosis of a spinal schwnnoma showing delayed presentation with atypical imaging findings is a challenge and must needs a high index of suspicion and appropriate surgical planning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
