Review Case Reports
Idiopathic intracranial hypertension occurred after spinal surgery: report of two rare cases and systematic review of the literature.
Idiopathic intracranial hypertension (IIH) is a relatively rare syndrome of increased intracranial pressure of unknown etiology. It is characterized by cerebrospinal fluid (CSF) opening pressure more than 250 mmH2O, with normal cranial imaging and CSF content. IIH occurred after spinal surgery is extremely rare. ⋯ IIH occurred after spinal surgery is relatively rare; the diagnosis is based upon exclusion of other diseases. IIH should be kept in mind in patients underwent spinal surgery as it could develop into irreversible intracranial hypertension.

Review Case Reports
Spinal Rosai-Dorfman disease: case report and literature review.
Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease (RDD) is a rare benign disease of dubious etiology that arises predominantly in lymph nodes with generalized fever and malaise. Isolated intraspinal involvement has its unique characteristics. The purpose of this study is to present the largest series of cases in the spinal Rosai-Dorfman disease literature to increase familiarity with its clinicopathologic features, diagnosis, and treatment of RDD from spine. ⋯ RDD with spinal involvement is uncommon and it is challengeable in making a certain diagnosis. Histopathologic characteristics and immunohistochemical findings are considered as the key points for the diagnosis of this disease. The optimal treatment remains controversial, and more efforts should be focused on the investigation of etiology and adjuvant therapy for relapsing cases or subresected lesions.

Review Case Reports
Primary intramedullary hydatid cyst: a case report and literature review.
Intramedullary hydatid cyst is extremely rare. We present a case of pathologically confirmed primary intramedullary hydatid cyst in an otherwise healthy patient. A 17-year-old boy presented with lumbar pain, weakness, and numbness in both lower limbs, and urinate difficulty interrupted for 2 years. ⋯ An intramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be a hydatid cyst by histopathologic examination after the surgical removal. Although extremely rare, primary intramedullary hydatid cyst pathology might be the cause of lumbar pain, weakness, and numbness in both lower limbs for those living in endemic areas. Surgical removement is feasible and effective for intramedullary hydatid cyst.

Review Case Reports
Migratory low velocity intradural lumbosacral spinal bullet causing cauda equina syndrome: report of a case and review of literature.
Migration of the bullet within the spinal subarachnoid space has long been recognized as unusual complication of spinal gunshot injury. ⋯ Caudal migration of the bullet within the lumbosacral subarachnoid space results in cauda equina syndrome. Surgical retrieval of the bullet ensures the early recovery of neurological symptoms. Prone patient positioning can influence bullet location. Intraoperative fluoroscopy prior to skin incision is essential in addition to preoperative imaging to locate the bullet and thus avoid incorrect lower level laminectomy. Trapping the bullet after durotomy using suction and dissector in reverse Trendelenburg position is a useful aid in bullet removal.

Axial fractures in patients with a previous C2-pelvis posterior instrumented fusion are rare and may be challenging to manage. Motion preservation in the axial spine for these patients is important, as the C1-2 and Occipit-C1 joints are their only remaining mobile spinal segments. In this unique report, we present for the first time the use of a fusionless occipitocervical operation for the treatment of a type II odontoid fracture and unilateral C2 pars fracture adjacent to a previous C2-pelvis posterior instrumented fusion. ⋯ In this one patient, instrumentation without fusion allowed for successful and timely union of a displaced odontoid fracture in a patient with a previous C2-pelvis fusion. Axial range of motion was preserved after instrumentation removal.
