Introduction and importance Pituitary apoplexy is defined as a sudden onset of neurologic deficit due to infarction or hemorrhage of the pituitary tumor. We report a case of emergency endoscopic surgery for pituitary apoplexy presenting as cerebral infarction due to ICA compression in a limited resources condition. Case presentation A 38-year-old female presented with acute onset of severe headache, decreased level of consciousness, decreased visual acuity bilaterally, aphasia, and right hemiparesis. Computed tomography angiography showed a hyperdense sellar mass with stenosis of the left ICA. The patient underwent emergent endoscopic transsphenoidal surgery for sellar decompression. Clinical discussion The epidermiology, presentation and diagnosis and strategy of treatments as well as their outcomes were discussed. Conclusion Pituitary apoplexy should be taken into consideration in a patient with increasing headache and neuro-ophthalmic symptoms. Pituitary apoplexy presenting as cerebral infarction is rare. The aim of surgery in emergency setting was sellar decompression. Endoscopic transsphenoidal surgery was an effective treatment., Highlights • Pituitary apoplexy should be taken into consideration in a patient with increasing headache and neuro-ophthalmic symptoms. • Pituitary apoplexy presenting as cerebral infarction is rare. • The aim of surgery in emergency setting was sellar decompression. • Endoscopic transsphenoidal surgery was an effective treatment.

Introduction: Clear cell chondrosarcoma (CCC) is a rare subtype of chondrosarcoma and it is commonly considered a low-grade tumor and less aggressive than atypical cartilaginous tumor (grade 1 central chondrosarcoma). However, the experience even of musculoskeletal tumor centres with this rare entity is limited. The aim of this study is to analyse our own treatment results and those of the literature regarding the therapy and outcome of this lesion. Material and Methods: 7 cases of CCC have been treated in our department between 2003 and 2015. Their follow-up data were collected retrospectively. 187 literature cases with histopathological and clinical characteristics were retrieved by means of a PubMed search with the key word “clear cell chondrosarcoma”. The data pertaining to treatment and follow up were extracted. We analysed the survival of patient and the risk factors for local recurrence (LR) as well as metastatic disease (MD). Results: The mean age at the time of diagnosis was 40 years. Two thirds of the patients were male. The mean follow-up time was 109 months. To our surprise, there was a high rate of LR (30%) and of MD (20%) when compared to low-grade conventional chondrosarcomas. 15% of LR and 20% of metastatic disease were observed after more than 10 years follow-up. Uncommon locations of MD such as in the spine is a unique observation in chondrosarcomas and underlines the high aggressiveness of this tumor. 10-year overall survival was almost 80%, 10-years disease free survival 60%. Positive margins (p = 0.038) and metastases (p = 0.006) impaired the overall survival significantly. The rate of local recurrence was significantly dependent on resection margin (p
