Background and importance: Ependymomas are tumours arising from the ependymal cells lining the ventricles and the central canal of the spinal cord. They represent the most common intramedullary spinal cord tumour in adults and are very rarely encountered in an extramedullary location. Only 40 cases of intradural extramedullary (IDEM) ependymomas have been reported, all of which were diagnosed pre-operatively as IDEM ependymomas on contrast-enhanced MRI. ⋯ A small residue is now stable at 2.5 years follow-up. Conclusions: Giant IDEM ependymomas are rare entities and pre-operative diagnosis can be challenging in some cases. Surgery represents the main treatment option being resolutive in most cases.

Case Reports
Patient presenting with frontal subperiosteal abscess and headache: a case of Pott's puffy tumour.
Chronic sinusitis can be complicated with erosion of anterior or posterior wall of the sinus; causing Pott's puffy tumour in the anterior, or epidural abscess in the posterior communication. A 65-year old man with a painful swelling in his forehead is presented. Pott's puffy tumour was diagnosed. ⋯ Postoperative course was uneventful. The presented case suggests that treatment of sinus osteomyelitis should comprise immediate surgical drainage and osteomyelitis debridement followed by long-term administration of antibiotics. MRI study with contrast should be obtained to rule out epidural abscess and dural infiltration.
