Anaplastic Astrocytoma (AA) is a relatively rare cancer, and is associated with a median life expectancy of 3 years after conventional therapy. Complete cure of the highly infiltrative AA is uncommon, and reports of positive outcome in cases of partial resection of AA are rare. Further, integrative approaches to the management of AA remain underexplored.

Spinal tumors are rare, of which intradural-extramedullary lesions form the majority of primary spinal tumors. Occasionally these may even be large, dumbbell shaped, with both intraspinal and extraspinal components. Complete gross total resection is the gold standard in the removal of these tumors since most are benign in nature.

Background: Placement of a syringo-subarachnoid shunt as a surgical management for syringomyelia has been well described in the literature. Good results in terms of clinical and radiological improvement have been documented especially for posttraumatic syringomyelia. Traditionally, this has been performed using open approaches which are fraught with risks of cerebrospinal fluid leak, delayed wound healing, and increased postoperative pain.

Background: Here, we present our experience with the minimally invasive (MI) transpsoas approach for lumbar corpectomy and stabilization. Transpsoas approach accesses the lumbar spine and includes both the direct lateral interbody fusion and extreme lateral interbody fusion techniques. Both procedures utilize a tubular retractor system which facilitates adequate retraction and direct visualization of the target, while supposedly reducing soft tissue trauma.

Cervical granulomatous infections of the posterior elements are very rare, it is often difficult to diagnose due to rarity and variable presentation of symptoms. Any cervical surgical procedure carries a certain morbid risk to the patient. We present a case of cervical 2-3 facet joint lesion which was managed by a minimally invasive technique with a favorable outcome.

Study Design: A retrospective study.

Purpose: To study the efficacy of augmented fixation for anatomical reduction of grade 2 and grade 3 listhesis in patients with osteoporosis.

Overview Of Literature: Spondylolisthesis in osteoporotic patients requiring spinal fixation are associated with complications such as loss of surgical construct stability, screw pulling out, and screw loosening.

Cerebral venous sinus thrombosis (CVST) is common in Asians, accounting for 15% of all strokes in the young. CVST causing malignant cerebral oedema with brain herniation and death are referred as malignant CVST. This study was aimed at evaluating the outcome of patients and factors predicting the outcome with malignant CVST after decompressive surgery.

Article Synopsis
  • The study discusses a unique complication of a ventriculoperitoneal (VP) shunt in an 8-year-old boy who experienced shunt dysfunction due to the migration of the shunt tube into the skull's diploic space, a rare occurrence not previously documented.
  • After diagnosing the malfunction, the surgical team successfully revised the shunt by removing the faulty system and placing a new one, leading to a significant recovery for the patient.
  • The authors suggest that careful placement of the shunt valve, considering the head position of paraplegic children, could prevent such unusual complications in the future.

Congenital occipital dermal sinus with an underlying dermoid is a rare, benign lesion of embryological origin and may occur anywhere along the neuraxis. We present a case of a 15-year-old girl with a vermian dermoid and an occipital dermal sinus. Gross total resection of the lesion was done and post-operative period was uneventful.
