Chondroblastoma of the Clivus: Case Report and Review.
Background and Importance Chondroblastoma is a benign primary bone tumor that typically develops in the epiphyses of long bones. Chondroblastoma of the craniofacial skeleton is extremely rare, with most cases occurring in the squamosal portion of the temporal bone. In this report, we describe the first case of chondroblastoma of the clivus presenting with cranial neuropathy that was treated with endoscopic endonasal resection. We review the literature on craniofacial chondroblastomas with particular emphasis on extratemporal lesions. Case Presentation A 27-year-old woman presented with severe headache, left facial dysesthesias, and diplopia. Physical examination revealed hypesthesia in the left maxillary nerve dermatome, and complete left abducens nerve palsy. Imaging demonstrated an expansile intraosseous mass originating in the upper clivus with extension superiorly into the sella turcica and laterally to involve the medial wall of the left cavernous sinus. The tumor was completely resected via an endoscopic endonasal approach, with postoperative improvement in lateral gaze palsy. Histopathology was consistent with chondroblastoma. Conclusion Chondroblastoma is a rare tumor of the craniofacial skeleton that should be included in the differential diagnosis of an osteolytic lesion of the clivus. Complete surgical resection remains the mainstay of treatment

A Multilayered Technique for Repair of the Suboccipital Retrosigmoid Craniotomy
Objective Our primary objective was to retrospectively review our single institution experience using an anatomic multilayered repair of the retrosigmoid suboccipital craniotomy. Our secondary objective was to review the existing body of literature on the repair of this craniotomy and compare our outcomes to previous results. Design Retrospective review of 25 consecutive patients undergoing repair for the retrosigmoid craniotomy. Setting University of California Davis Medical Center (2010-2016). Participants A total of 25 consecutive patients who underwent retrosigmoid craniotomy and repair. Exclusion criteria included patients who were under the age of 18 years. Main Outcome Measures Main outcomes included incidence of postoperative headache, cerebrospinal fluid leak, and wound infections. Results Postoperative headache was reported in two patients in this series (8%). None of the patients in the series developed cerebrospinal fluid leak or wound infections. Mean follow-up period was 16 months. Conclusion Our multilayered anatomic repair after retrosigmoid suboccipital craniotomy results in favorable clinical results and may help reduce the risks associated with this operation

Cervical spine fractures in osteopetrosis: a case report and review of the literature
While management of appendicular fractures has been well described in the setting of osteopetrosis, there is limited information on managing fractures of the axial spine. Here we present an osteopetrotic patient with multiple traumatic multiple, comminuted, unstable cervical spinal fractures managed with non-operative stabilization, and provide a review of the pathophysiology, genetic characteristics, and special considerations that must be explored when determining operative versus non-operative management of spinal injury in osteopetrosis. A PubMed query was performed for English articles in the literature published up to June 2016, and used the following search terms alone and in combination: "osteopetrosis", "spine", "fractures", "osteoclasts", and "operative management". Within four months after initial injury, treatment with halo vest allowed for adequate healing. The patient was asymptomatic with cervical spine dynamic radiographs confirming stability at four months. On four-year follow up examination, the patient remained without neck pain, and CT scan demonstrated partially sclerotic fracture lines with appropriate anatomical alignment. In conclusion, external halo stabilization may be an effective option for treatment of multiple unstable acute traumatic cervical spine fractures in patients with osteopetrosis. Given the challenge of surgical stabilization in osteopetrosis, further research is necessary to elucidate the optimal form of treatment in this select patient population
