Spinal myelolipoma - an extremely rare pathology within the lumbar spine: a case report and literature review.

Myelolipoma is a benign tumor containing mature adipose cells and a combination of myeloid and erythroid elements. This tumor is typically found in the adrenal glands; however, it has been detected outside the adrenal glands in rare cases. We report an extremely rare case of myelolipoma in the lumbar spine causing significant neural compression due to the involvement of the posterior spinal elements. Given the significant neurological deficit, the patient was surgically managed as soon as possible. Extra-adrenal myelolipomas are rare lesions, and only one case has been reported in the spine so far. However, this diagnosis should be considered in cases with its characteristic imaging features.

Recurrent posterior fossa intracranial capillary hemangioma in a pregnant woman: A case report and review of literature.

Introduction: Intracranial capillary hemangioma (ICH) is a rare tumor with a slightly higher incidence in women. Surgical management of ICH during pregnancy requires a joint decision, for it has been a contentious issue owing to the inadequate number of cases. Presentation of case: A 23-year-old female with an ICH in the posterior fossa underwent subtotal tumor resection (STR). One year later, she was referred to the neurosurgery department in the 8th week of pregnancy due to a progressive headache, vomit, and a bulging occipital mass. Subsequent to an abortion, preoperative angiography and Bleomycin injection were performed, and the tumor was totally resected thereafter. Over a one-year follow-up, her symptoms faded, and she experienced no recurrence. Discussion: ICH, a highly vascular entity, poses a substantial intraoperative bleeding risk. During the first surgery, intraoperative bleeding deterred the surgeon from a gross total resection (GTR), leading to a recurrence due to the growth of residual tissue during pregnancy. Having aborted the fetus, the patient underwent angioembolization to lessen the risk of intraoperative bleeding before reoperation, rendering it more possible for the surgeon to achieve GTR. Accordingly, quality of resection and a multidisciplinary approach is necessary to ensure optimal treatment. Conclusion: There is a growing consensus that not only is STR a contributory factor in ICH recurrence, but female hormones and increased cardiac output in pregnancy might play a pivotal role in the progression of the tumor. Thus, paying further attention to pregnant or peripartum patients with suspected ICH should assume greater significance.

The effect of combination therapy with erythropoietin and methylprednisolone in patients with traumatic cervical spinal cord injury: a pilot randomized controlled trial.

STUDY DESIGN: Pilot double-blinded randomized controlled trial. OBJECTIVES: To investigate the additive effect of recombinant human erythropoietin (rhEPO) on functional outcome and disability in patients with traumatic cervical spinal cord injury (TCSCI). SETTINGS: University-affiliated hospital in Mashhad, Iran. METHODS: Patients with acute TCSCI admitted within 8 h after injury were randomly assigned to receive only methylprednisolone (M group) or rhEPO 500 IU/mL plus methylprednisolone (M + E group). All the patients underwent surgery within the next several days. Neurological function was assessed on admission, and at 6th and 12th months after the injury according to the sphincter function and American spinal cord injury association (ASIA) scale. RESULTS: Overall, 54 patients (mean age: 39.7 ± 13.3 years) including 46 (85%) males were studied in two groups of 27. The likelihood of developing adverse neurological outcomes (ASIA impairment score of A compared to D or E) was not significantly different between the groups after 6 (OR = 0.39, 95% CI = 0.03-4.80, P = 0.46) and 12 months (OR = 0.83, 95% CI = 0.11-6.11, P = 0.86). The groups also showed no significant difference in 1-year mortality (OR = 0.83, 95% CI = 0.25-2.74, P = 0.76). CONCLUSIONS: It is not clear whether combination therapy with erythropoietin compared to methylprednisolone alone improves neurological functions of patients with TCSCI. Our study provides interim data to guide future larger definitive trials.

Outcomes of dura-splitting technique compared to conventional duraplasty technique in the treatment of adult Chiari I malformation: a systematic review and meta-analysis.

Chiari malformation type I is a developmental abnormality with an array of surgical techniques introduced for the management of it. The most common technique is foramen magnum decompression with duraplasty. Dura-splitting technique as one of the non-dura-opening techniques is a less known procedure that spares the internal layer of the dura and can theoretically result in fewer complications compared to duraplasty. So, we performed a review of literature and meta-analysis on different clinical and radiological aspects of this technique and compared its outcomes to duraplasty. MOOSE guidelines were followed. A systematic search of three databases based on predefined search strategy and inclusion/exclusion criteria was performed. After quality assessment and data extraction by two authors, summarized data were presented in form of tables, and meta-analysis results were illustrated in forest plots. A review of 10 included studies consisting of 370 patients revealed significantly shorter operation duration and less intraoperative blood loss in the dura-splitting technique compared to duraplasty. Interestingly, there was no significant difference between these two techniques in terms of clinical and radiological outcomes. Overall complication rate and incidence of CSF-related complications or infections were significantly in favor of the dura-splitting technique. Dura-splitting technique can be considered as a safe and effective surgical procedure for Chiari I malformation with comparable outcomes and fewer complications compared to duraplasty, although this interpretation is derived from retrospective observational studies and lack of a prospective clinical trial is evident.
