Intramedullary mature teratoma of spinal cord: A rare tumor with review of literature.

BACKGROUND: Spinal teratomas are rare in adults. The clinical findings are nonspecific, reflecting only in the intramedullary location of these lesions. The potential differential diagnosis for intramedullary spinal teratomas include schwannomas, dermoids, epidermoids, and neurofibromas. CASE DESCRIPTION: A 25-year-old male presented with RLE weakness (iliopsoas/quadriceps [4/5], and extensor hallucis longus/dorsiflexor [0/5]) and urinary incontinence. As the contrast, MR showed a heterogeneous intramedullary lesion with well-defined edges located at the T12-L1 level, the patient underwent a focal laminectomy for gross total tumor excision. Pathologically, it proved to be a mature teratoma. CONCLUSION: Teratomas should be considered among the differential diagnostic considerations for intramedullary spinal cord lesions. Although gross total resection is preferred, these lesions have a low recurrence rate, and therefore, partial removal is also valid, where lesions are densely adherent to adjacent neural structures.

Solitary osteochondroma of dorsal spine causing canal stenosis with myelopathy - A case report with review of literature.

BACKGROUND: Osteochondroma is a common benign tumor arising from the long bones. It rarely arises in the spine, where it can cause mild symptoms such as backache all the way up to compressive myelopathy. Malignant transformation has also been reported. Here, the authors present a 52-year-old male with myelopathy attributed to a rare thoracic solitary osteochondroma. CASE DESCRIPTION: A 52-year-old male presented back pain radiating into both lower extremities with paresthesia to the toes of 1 year's duration. On examination, he exhibited hyperactive bilateral lower extremity reflexes with bilateral Babinski signs, and focal sensory changes to pin, and touch appreciation in the left L5S1 distributions. Computed tomography and magnetic resonance imaging showed an abnormal bony mass arising from the posterior arch of T10 with protrusion into the spinal canal resulting in marked canal/cord compression. Surgery included a D10 laminectomy with en bloc resection of the lesion. Postoperatively, the patient's symptoms resolved. Histologically, the lesion was an osteochondroma. CONCLUSION: When patients present with myelopathy, one should include osteochondromas among the differential diagnostic possibilities.

Prospective Randomized Comparative Study to Evaluate Epidural Fibrosis and Surgical Outcome in Patients Undergoing Lumbar Laminectomy with Epidural Autologous Free Fat Graft or Gelfoam: A Preliminary Study.

INTRODUCTION: Epidural fibrosis (EF) contributes to unsatisfactory relief of symptoms and failed back syndrome after spine surgery. EF around the nerve root can be more refractory to treatment than the original disc herniation itself. Reoperation on the scar can produce more scarring. Few studies have been conducted regarding the type of material to be used for decreasing EF. MATERIALS AND METHODS: The prospective randomized comparative study was conducted in the Department of Neurosurgery and Radiodiagnosis, of a tertiary care hospital. Informed and written consent was obtained. Patients previously unoperated with symptoms and radiological features of lumbar spinal canal stenosis were included in the study. Fifteen patients were assigned to Group A (free fat graft) and 15 patients in Group B (Gelfoam group). Postoperatively, at 3 and 6 months, clinical outcome was evaluated and EF was assessed on CE-MRI. RESULTS: Age and sex were comparable in both groups. The pain relief at 3 and 6 months was more in Group A as compared to Group B. In Group A, on CEMRI at 3 months, 87% of patients had none to mild fibrosis, with none had extensive fibrosis. The CEMRI at 6 months showed no increase in fibrosis. In Group B, 80% of patients had none to mild fibrosis at the end of 3 months. At 6 months, 13.3% patients had extensive fibrosis. The extent of EF was found to be statistically significant at 6 months postsurgery. CONCLUSION: Use of free fat graft at laminectomy site helps in reducing EF.

Endoscopic Endo-Nasal Trans-Sphenoidal Excision of Pituitary Tumors: An Institutional Experience.

To analyze the clinical presentation, management and outcomes of patients with pituitary adenoma treated by Endoscopic Endo-nasal Trans-sphenoidal (EETS) excision. Study was conducted on the basis of medical records of 14 patients who had undergone EETS excision of pituitary adenomas. The data obtained was assessed for demographic and clinical characteristics, radiographic features and post-operative outcomes. Study included 10 males and 4 females. Mean age of patients was 46.43 years (range 16-70 Years). Most common presentation was diminished vision reported in 79% patients. Features of acromegaly encountered in 21% cases. Location of majority of tumors was sellar with supra-sellar extension (71%) followed by sellar (14%), sellar with para-sellar extension (7%) and sellar with supra-sellar and para-sellar extensions (7%). Total tumor resection was achieved in 64% cases and sub-total resection in 36% cases. One of the lesions on biopsy revealed granulomatous pathology. No post-operative complication was seen in 71% patients. Transient Diabetes Insipidus was observed in 21% cases that resolved within 3-4 days. One patient expired due to meningitis and septicemia. One patient had CSF leak that was effectively managed by placing lumbar drain. There was significant improvement in visual symptoms and hormonal levels. Average hospital stay was 13.54 days and mean follow up period was 13 months. EETS approach is safe, minimally invasive and effective surgical technique for resection of pituitary adenomas with low post-operative morbidity, reduced hospital stay and better remission of symptoms.

Do they hear what we speak? Assessing the effectiveness of communication to families of critically ill neurosurgical patients.

BACKGROUND AND AIMS: Clinician-family communication must be effective for medical decision making in any Intensive Care Unit (ICU) setting. We performed a prospective study to assess the effectiveness of communication to families of critically ill neurosurgical patients based on the two criteria of comprehension and satisfaction. MATERIALS AND METHODS: The study was conducted on 75 patients in a 15 bedded neurosurgical ICU. An independent investigator assessed the comprehension and satisfaction of families between the 3(rd) and the 5(th) day of admission in ICU. Comprehension was tested using three components, that is, comprehension of diagnosis, prognosis and treatment. The satisfaction was measured using a modified version of the Critical Care Family Needs Inventory (CCFNI) (score of 56-extreme dissatisfaction and 14-extreme satisfaction). RESULTS: Poor comprehension was noted in 52 representatives (71.2%). The mean satisfaction score as measured by the CCFNI score was 28. Factors associated with poor comprehension included increasing age of patient representative (P = 0.024), higher simplified acute physiology score (P = 0.26), nonoperated patients (P = 0.0087) and clinician estimation of poor prognosis (P = 0.01). Operated patients had significantly better satisfaction score (P = 0.04). CONCLUSION: Families of patients were reasonably satisfied, but had poor comprehension levels of the patient's illness. The severity of the patient's illness, poor prognosis as estimated by the physician and nonoperated patients were independent predictors of poor comprehension. Extra effort to communicate with patient representatives at risk of poor comprehension and provision of a family information leaflet could possibly remedy this situation.

Craniovertebral junction melanocytoma: a case report.

Melanocytomas are rare melanocytic tumors of the central nervous system and its presence at the foramen magnum is extremely rare. We report a case of a 55-year-old male presenting with progressive quadriparesis over one year. Imaging showed a well-defined intradural extramedullary lobulated mass at craniovertebral junction towards the left side and extending to left C2-3 neural foramina. Patient was operated through foramen magnum approach with near total excision of tumor. On a ten-month follow up, he was ambulatory with normal motor power on right side of body and left lower limb and with motor power of 4-/5 in left upper limb. Histopathology and immunohistochemistry confirmed the lesion to be a melanocytoma.

Traumatic bilateral basal ganglia hematoma: A report of two cases.

Traumatic Basal ganglia hemorrhage is relatively uncommon. Bilateral basal ganglia hematoma after trauma is extremely rare and is limited to case reports. We report two cases of traumatic bilateral basal ganglia hemorrhage, and review the literature in brief. Both cases were managed conservatively.
