Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery...

OBJECTIVE In the past decade, the role of the endoscopic endonasal approach (EEA) has relevantly evolved for skull base tumors. In this study, the authors review their surgical experience with using an EEA in the treatment of clival chordomas, which are deep and infiltrative skull base lesions, and they highlight the advantages and limitations of this ventral approach. METHODS All consecutive cases of chordoma treated with an EEA between 1998 and 2015 at a single institution are included in this study. Preoperative assessment consisted of neuroimaging (MRI and CT with angiography sequences) and endocrinological, neurological, and ophthalmological evaluations, which were repeated 3 months after surgery and annually thereafter...

PURPOSE: Sphenoid bone dysplasia in neurofibromatosis type 1 is characterized by progressive exophthalmos and facial disfiguration secondary to herniation of meningeal and cerebral structures. We describe a technique for reconstruction of the sphenoid defect apt at preventing or correcting the ocular globe dislocation. METHODS: After placement of spinal cerebrospinal fluid drainage to reduce intracranial pressure, the temporal pole is posteriorly dislocated extradurally...

INTRODUCTION: Posterior C1-C2 fusion is a highly successful treatment for atlantoaxial instability and other pathologies of the cervical spine, with fusion rates approaching 95%-100%. However, poor visualization of the lateral masses of C1 secondary to the course of the C2 nerve root along with blood loss from the venous plexus and compression of the C2 nerve from lateral mass screws are technical obstacles that can arise during surgery. Thus, sacrifice of the C2 nerve root has long since been debated in fusions involving the C1 and C2 vertebral bodies...

A 2-mo-old pet chicken ( Gallus domesticus) was presented because of lameness and a hind limb mass of 1 mo duration. Radiographs revealed a soft tissue mass extending from the mid-femur into the body wall. Cytology of a sample obtained from a fine-needle aspirate was unremarkable. The bird was prepared for surgical investigation of the mass but died acutely at the time of pre-medication. Autopsy revealed an extradural mesenchymal neoplasm that focally compressed the lumbar spinal cord, extended into and along the adjacent nerve structures, and displaced the kidneys, skeletal muscle, and body wall...

Spinal extradural arteriovenous fistulas (SEDAVF) with intradural drainage are uncommon vascular lesions that cause venous congestive myelopathy. We present three SEDAVF with intradural drainage treated with surgical disconnection of the intradural drainage via a single level laminectomy, followed by transarterial embolization (TAE) with Onyx if spontaneous thrombosis of the extradural fistula did not occur spontaneously. All patients improved their neurological condition and no congestive myelopathy recurrence was noted after mean follow-up of 84 months...

OBJECTIVE Post-dural puncture headaches are common, and the treatment of such headaches can be complex when they become chronic. Among patients with spontaneous spinal CSF leaks, digital subtraction myelography (DSM) can localize the exact site of the leak when an extradural CSF collection is present, and it can also demonstrate CSF-venous fistulas in those without an extradural CSF collection. The authors now report on the use of DSM in the management of patients with chronic post-dural puncture headaches...

PURPOSE: Intraspinal hematoma is a serious condition, and early diagnosis is necessary to permit emergency treatment. Among such hematomas, non-traumatic spinal subdural hematoma is a rare occurrence. We have experienced three patients with surgically proven subdural spinal hematoma, and here we report these cases with a review of their clinical and imaging characteristics. METHODS: All three cases were idiopathic with no history of disease, no coagulopathy, and no trauma...

Spinal meningiomas are the most common of adult spinal tumors. Spinal meningiomas account for up to 45% of all intradural spinal tumors in adults and up to 25% of all spinal tumors. While spinal meningiomas are traditionally classified as intradural lesions, up to 14% may have an extradural component. Preoperative evaluation and directed use of imaging techniques are key in these rare but observed cases, to accurately diagnose and direct therapy. In this report, the authors present a case of a 61-year-old female with an incidentally found, exclusively extradural thoracic meningioma treated with surgical resection, highlighting key radiographic pearls in the evaluation of these uncommon lesions...

When ossification of the yellow ligament (OYL) occurs in the lumbar spine and extends to the lateral wall of the spinal canal, facetectomy is required to remove all of the ossified lesion and achieve decompression. Subsequent posterior fixation with interbody fusion will then be necessary to prevent postoperative progression of the ossification and intervertebral instability. The technique of lateral lumbar interbody fusion (LLIF) has recently been introduced. Using this procedure, surgeons can avoid excess blood loss from the extradural venous plexus and detachment of the ossified lesion and the ventral dura mater is avoidable...

Extracranial metastasis of glioblastoma multiforme (GBM) is rare, but has recently been reported with increasing frequency. GBM metastases typically present after a biopsy or resection of the primary tumor. An otherwise healthy 54year-old woman presented with recurring pleural effusions originally believed to be from a primary lung malignancy. The patient subsequently experienced a generalized tonic clonic seizure and a right temporal brain mass was discovered. The patient later developed weakness and radiculopathy, and an extramedullary extradural mass spreading from C7 to T6 was discovered...

Purpose Thoracic disk herniation is uncommon. It still represents a challenge for spinal surgeons. Multiple surgical strategies are available and, often, they are matter of debate. We describe a preliminary experience about a combined extra-intra dural approach for posterolateral disk herniation in patients affected by spinal cord compression. METHODS: We performed a combined extra-intra dural approach in two preliminary cases. We performed bilateral laminectomy of adjacent vertebrae and unilateral partial medial arthrectomy of the involved segment...

BACKGROUND: The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. OBJECTIVE: To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. METHODS: Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. RESULTS: Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished...

CASE DESCRIPTION An 11-year-old English Cocker Spaniel was evaluated because of chronic progressive ataxia of the hind limbs. CLINICAL FINDINGS The dog had no history of previous illness, and findings of physical examination and laboratory tests were unremarkable. Neurologic examination revealed that the dog was ambulatory with severe ataxia of the hind limbs. Proprioception was decreased in the right and left hind limbs (right affected more than left), and spinal reflexes were bilaterally unremarkable. Moderate signs of pain were detected during palpation of the lumbar portion of the vertebral column...

Meningiomas are common spinal tumor and mostly located at intradura. Recurrence rate after surgery for extradural meningioma was higher than intradural meningioma. A patient with intra and extradural spinal meningioma was treated and discussed its features and clinical management. A 41-year-old woman noted numbness of bilateral legs, gait disturbance, and mild bladder disturbance for over the two-month period. Magnetic resonance imaging revealed an epidural mass at T8-9 involving the dura mater from the left side...

We report a case of malignant transformation of an intracranial extradural epidermoid cyst into squamous cell carcinoma (SCC), that presented with cerebrospinal fluid (CSF) leakage at the time of recurrence. Intracranial epidermoid cysts are histologically benign and slow-growing neoplasms. They are congenital lesions that develop from ectodermal remnants during neuroembryogenesis. Malignant transformation of epidermoid cysts into SCC is very rare. Various clinical presentations of these tumors after malignant transformation are mentioned in the literature...
