Low-grade fibromyxoid sarcoma (LGFMS), an uncommon soft tissue tumor, generally occurs in extremities and is characterized by an aggressive clinical course with frequent recurrences. Primary intracranial occurrence of LGFMS is rare. The few existing descriptions present the clinicopathologic aspects of LGFMS and lack information from a radiologic perspective. In these reports, the lesions appeared solid on imaging. ⋯ This report emphasizes the radiologic aspects of LGFMS and describes an atypical solid-cystic appearance of this uncommon central nervous system tumor. This adds another facet to the imaging of LGFMS. Although rare, LGFMS can form a differential diagnosis of dural-based lesions.

Because of the paucity of relevant data, treatment and outcomes in intracranial atypical meningioma (AM) remain unclear. The aim of this study was to find useful factors predicting survival and to evaluate the role of postoperative radiation after surgery. ⋯ GTR is the first choice for patients with AM. We recommend that patients with secondary tumors receive radiotherapy after surgery.

We sought to describe a novel technique in managing a patient with adjacent segment disease at the L5/S1 level. ⋯ This minimally invasive technique is effective in terms of decompression and fixation. It could be used as an alternative method to treat patients with L5/S1 adjacent segment disease.

Granulomatous reaction on a double-level cervical total disc arthroplasty : case report.
Cervical total disc arthroplasty (TDA), or cervical artificial disc replacement, is an alternative technique to anterior cervical discectomy and fusion for treatment of symptomatic degenerative cervical spine disease. The main goal of TDA is to maintain cervical motion and lower the risk of deterioration of adjacent levels. Granuloma formation on a cervical TDA is exceptional. ⋯ We report a third case of granulomatous reaction on nylon thread extrusion after partial breakdown of a prosthesis for cervical TDA.

Case Reports
Clinical Perspective on Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease).
Dysplastic gangliocytoma of the cerebellum, also called Lhermitte-Duclos disease (LDD), is known as a rare, benign brain tumor. Around 200 cases have been reported. ⋯ Preoperative diagnosis based on magnetic resonance imaging is 50% in adults and 16.7% in pediatrics. Diagnostic tiger stripes are not always seen in pediatric cases. The prognosis of the disease is good if total resection can be achieved. Further examinations for PTEN mutation and other comorbidities are recommended.
