The median survival for patients operated for cerebral metastases in our institution is 29 weeks. Those who are operated and receive Rt, have a longer survival, than those who did not receive Rt.
RESUMEN
Presentamos el caso de una mujer de 13 años con un gran tumor de características óseas en la fosa infratemporal derecha, el cual fue biopsiado mediante un abordaje endoscópico transeptal transpterigoídeo. La biospia mostró un osteocondroma. Describimos el caso y discutimos sus aspectos relevantes.Palabras clave: Osteocondroma, cirugía endoscópica nasal, abordaje transpterigoídeo.
ABSTRACTWe report the case of a 13-year-old woman with a large tumor with osseous appearance in her right infratemporal fossa, which was biopsied through an endoscopic transpterygoid approach. The biopsy showed an osteocondroma. We described the case and discuss its relevant aspects.
RESUMEN
ABSTRACTWe report the case of a 56-year-old woman with diagnosis of esthesioneuroblastoma Kadish C/Hyams II treated with a purely endonasal endoscopic resection and adjuvant radiotherapy. We described the case and discuss its relevant aspects.
Pancoast tumors represent a rare presentation of lung cancer. Their particular location delays diagnosis and makes resection difficult. Nevertheless recent advances in surgical techniques and multi-modality therapy (chemo-radiation followed by surgery) had increased resection rates and achieved long term survival. We present the case of a 62-year-old woman with an extensive Pancoast tumor and a synchronous hypofisiary lesion. We carried out an exhaustive staging workout determining that the infratentorial lesion was a hypofisiary adenoma. She underwent induction chemo-radiotherapy and posterior surgery. A complete resection was possible with prolonged survival and minimal functional disability. We present the evolution in management of Pancoast tumors and our approach to patients with suspicious metastases in potentially resectable tumors.
Hypopituitarism after traumatic brain injuryHypopituitarism after moderate or severe traumatic brain injury (TBI) is usually underdiagnosed and therefore undertreated. Its course can be divided in an acute phase during the first 14 days after TBI with 50 to 80% risk of hypopituitarism, and a chronic phase, beginning three months after the event, with a prevalence of hypopituitarism that ranges from 2 to 70%. Its pathophysiology has been addressed in several studies, suggesting that a vascular injury to the pituitary tissue is the most important mechanism during the acute phase, and an autoimmune one during chronic stages. In the acute phase, there are difficulties to correctly interpret pituitary axes. Hence, we propose a simple and cost-effective algorithm to detect and treat a potential hypothalamic-pituitary-adrenal axis impairment and alterations of sodium homeostasis, both of which can be life-threatening. In the chronic phase, post-concussion syndrome is the most important differential diagnosis. Given the high prevalence of hypopituitarism, we suggest that all pituitary axes should be assessed in all patients with moderate to severe TBI, between 3 to 6 months after the event, and then repeated at 12 months after trauma by a specialized team in pituitary disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
