We present a case of a solitary fibrous tumour (SFT) resembling an aggressive angiomyxoma/liposarcoma on radiological imaging, causing significant diagnostic challenges preoperatively. A 76-year-old male was incidentally found to have a large pelvic mass on a CT scan. Further evaluation with an MRI scan confirmed a presacral mass containing fat and soft tissue components. It was inseparable from the sacrococcygeal spine, rectal serosa and the posterior wall of the urinary bladder, but no evidence of invasion was seen...

(no author information available yet)
Dural tears (DT) and the consequent cerebral spinal fluid (CSF) leak are not rare in spine surgeries. CSF leak can be troublesome, leading to pseudomeningocele, cutaneous CSF fistula, and meningitis. Revision surgery is unavoidable in some cases. The reported incidences of DT and CSF leak are different according to the various pathologies. Ossification of the posterior longitudinal ligament, revision spine surgery and multi-segment laminectomy have higher risks for DT. Various techniques have been described to manage this complication, such as bed rest, repair with dural substitutes, fibrin glue, gelatin sponge, lumbar drain, muscle flap, etc...

BACKGROUND: Minimally invasive surgery (MIS) technique is becoming the standard tissue sparing approach for decompression of lumbar central and lateral recess stenosis, intervertebral disc herniation, or any situation that would have required extensive open decompression laminectomy. Full-endoscopic or arthroscopic assisted surgery is arguably the "ultra-MIS" approach to lumbar spinal pathology. Age and body mass index (BMI) are significant risk factors to be considered in full-endoscopic assisted ultra-MIS...
