Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures. We present our initial experience with two cases operated on using O-arm-based spinal navigation at the Clinic of Neurosurgery in St George University Hospital, Plovdiv, Bulgaria. In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation. In the second case, we performed O-arm-navigated corpectomy of the fifth cervical vertebra and anterior spinal reconstruction and fusion with titanium expandable mesh and cervical plate in connection with degenerative narrowing of the cervical spinal canal that lead to clinically manifested myelopathy...

BACKGROUND: Intracranial hypotension secondary to spontaneous spinal cerebrospinal fluid (CSF) fistula is a rare condition which can have serious sequelae. Early diagnosis and treatment can be challenging. CASE DESCRIPTION: We present a case of a 17-year-old man who presented with a history of sudden onset, postural headaches, associated with upper thoracic back pain. Magnetic Resonance Imaging (MRI) demonstrated a thoracic extradural fluid collection and slumping of the brain within the posterior fossa...

We present a case of a man aged 20 years who was referred with the inability to open his mouth as a consequence of severe ankylosis of his temporomandibular joint. He had previously undergone an attempt to release the ankylosis at the referring institution; however, this was complicated by an extradural haematoma as a result of iatrogenic injury. We describe a one-stage procedure which provided safe excision of the ankylotic mass along with immediate total joint replacement with a custom implant. We advocate the use of preoperative vascular imaging along with the use of custom-made cutting guides to minimise vascular injury...

The cerebellopontine angle (CPA) is a narrowed skull base area, containing important cranial nerves and vessels and bordering with eloquent areas of the posterior fossa. Tumors of the CPA are a heterogeneous group and can arise extradural, intradural-extraaxial or intraaxial. Accordingly, their vascular supply changes, depending on their anatomical origin. Symptomatic, large CPA tumors require surgical resection in order to prevent irreversible, severe neurological damages. However, its tight and strategical location make surgery in the CPA very challenging and require appropriate pre-surgical planning...

Stereotactic radiosurgery (SRS) has emerged as a treatment option for patients with spinal metastatic disease. Although SRS has been shown to be successful in a multitude of extradural metastatic tumors causing cord compression, very few cases of intradural treatment have been reported. The authors present a rare case of an intradural extramedullary metastatic small cell lung cancer lesion to the cervical spine resulting in cord compression in an area that had also been extensively pretreated with conventional external-beam radiation therapy...

Pseudomeningocele is a collection of the cerebrospinal fluid in the extradural space due to a defect in the dura-arachnoid layer of the meninge, and manifests as a fibrous capsule in the space of subcutaneous tissues. Classically, growing skull fracture caused by the pseudomeningocele is not uncommon in the pediatric age group. However, a posttraumatic intradiploic pseudomeningoceles is extremely rare, and only a few patients have been described. Herein, the authors present a 6-year-old girl who developed an intradiploic pseudomeningocele of the occipito-cervical region after a severe head trauma...

BACKGROUND: Myeloid sarcoma (MS) is a malignant tumor that usually occurs concomitantly with or following acute myeloid leukemia (AML). Cavernomas are benign congenital malformations that are unusual in the spine and exceedingly rare in pure extradural locations. CASE DESCRIPTION: We report a 73-year-old female with a previous medical history of AML in remission for 3 years who presented with symptoms of low back pain and right lower extremity radiculopathy. A magnetic resonance scan showed an extradural, foraminal lesion centered at the L2 level involving the right L2 nerve root...

Osteolipoma is a rare variant of the ubiquitous lipoma. Published literature appears in the form of isolated case reports affecting soft tissue structures in the head, neck and rarely affecting the spine. We present a unique instance of an intraspinal osteolipoma in the cervical spine, without evidence of accompanying spinal dysraphism and an atypical clinical presentation of isolated dorsal column dysfunction. We describe the clinical presentation, operative procedure and post-operative outcomes with histopathological findings of this rare entity...

INTRODUCTION: Chiari malformation type-1 (CM-1) may be treated by intradural (ID) or extradural (ED) posterior fossa decompression, although the optimal approach is debated. The Chiari Severity Index (CSI) is a pre-operative metric to predict patient-defined improvement after CM-1 surgery. In this study, we evaluate the results of ID versus ED decompression and assess the external validity of the CSI. METHODS: We performed a retrospective cohort study of pediatric CM-1 patients undergoing decompression at a single academic children's hospital...

BACKGROUND: Intracranial carotid sympathetic plexus schwannoma (CSPS) is extremely rare; thus differential diagnostic criteria, optimal surgical strategies, and even a precise definition are lacking. Here we describe a case of CSPS and propose a definition and classification for previously reported cases. CASE DESCRIPTION: A 54-year-old man presented with hypacusis and abducens nerve palsy. Radiologic examinations revealed a well-enhanced mass at the right medial temporal base with erosion of the petrous apex and intact perilesional cortical bone...

Spinal tumors are classically grouped into 3 categories: extradural, intradural extramedullary, and intradural intramedullary. Spinal tumors may cause spinal cord compression and vascular compromise resulting in pain or neurologic compromise. They may also alter the architecture of the spinal column, resulting in spinal instability. Oncologic management of spinal tumors varies according to the stability of the spine, neurologic status, and presence of pain. Treatment options include surgical intervention, radiation therapy, chemotherapy, and hormonal manipulation...

A 9-month-old domestic shorthair cat had progressive ambulatory paraparesis, proprioceptive ataxia, and thoracolumbar hyperesthesia. An extradural mass affecting the left pedicle and lamina of the second lumbar vertebra (L2) causing marked spinal cord impingement was identified in magnetic resonance (MR) images. The mass was predominantly calcified in computed tomographic (CT) images. A hemilaminectomy was performed to resect the mass. Clinical signs were greatly improved at 12-month follow-up. The histopathologic diagnosis was vascular hamartoma...

BACKGROUND: Masson hemangioma is a rare pathologic entity characterized by intravascular papillary endothelial hyperplasia. Although benign, this hemangioma grows to form an expansile compressing mass. This lesion is mostly seen in skin and subcutaneous tissue. Occurrence in the central nervous system is rare. Still rarer is a spinal location with only 5 case reports published to date in the literature. CASE DESCRIPTION: A 32-year-old man presented with paraplegia secondary to extradural compression at the T4-5 level...

Spinal nerve root hemangioblastomas present mostly as intradural-extradurally. Purely extradural spinal nerve root hemangioblastoma is a very rare entity. In this study, we aimed to analyze epidemiological perspectives of purely extradural spinal nerve root hemangioblastomas presented in English medical literature in addition to our own exemplary case. PubMed/MEDLINE was searched using the terms "hemangioblastoma," "extradural," "spinal," and "nerve root." Demographical variables of age, gender, concomitant presence of von Hippel-Lindau (VHL) disease; spinal imaging and/or intraoperative findings for tumor location were surveyed from retrieved articles...

BACKGROUND: Spinal arteriovenous shunts are a common spinal vascular disorder. However, they can have a misleading clinical presentation and poor prognosis. They are classified into 4 types according to shunt points and drainage route, among which extradural arteriovenous fistula (eAVF) is the most rare, comprising only 1% of all spinal arteriovenous shunts. We report an extremely rare case of coexistent eAVF at the craniocervical junction and soft tissue arteriovenous malformation within the same metamere...
