ABSTRACT
BACKGROUND: Intrasaccular devices provide a method for treating complex aneurysms without leaving metallic materials in the parent artery. Compared to other well-studied devices in neurointervention, the Contour device is relatively new as an intrasaccular flow diverter. This study examines its use in cases of incidental aneurysms and its application in the acute treatment of ruptured aneurysms. Additionally, it covers potential complications that may arise and methods for prevention. METHODS: We conducted a retrospective analysis of 25 patients who underwent treatment with the Contour device at 3 hospital centers. We collected data related to age, gender, baseline modified Rankin Scale, personal habits, medical history, procedure details, and angiographic results according to the Woven endobridge occlusion scale. RESULTS: A total of 15 patients (65.5%) achieved a satisfactory angiographic result (grade 0-0') 1 year after embolization. Contrast stagnation was observed in 14 patients (58.3%). Intraprocedural complications, such as device displacement, were documented in 3 patients (12%), while 2 patients (8%) had aggregates attached to the device. Regarding late complications, 5 patients (20%) experienced device displacement and 1 patient had a minor stroke (4%). Retreatment was necessary for 3 patients (12%), involving a flow diverter, stenting, and coiling. CONCLUSIONS: In summary, the Contour device offers a viable option for treating complex aneurysms. While initial results are promising, it is crucial to acknowledge a learning curve to minimize complications and achieve satisfactory angiographic results without the need for additional treatments.

La cerebelitis aguda es una de las causas principales de disfución cerebelar aguda en pediatría; puede ser infecciosa, postinfecciosa o posvacunal, y generalmente es de etiología viral. El diagnóstico es difícil porque la clínica presenta sólo algunos de los signos de patología cerebelosa y el líquido cefalorraquídeo puede ser normal. La afectación de un único hemisferio cerebeloso, hemicerebelitis, es muy infrecuente, hay publicados tres casos hasta el año 2003. La resonancia magnética muestra edema cerebeloso unilateral con realce que sigue la morfología de las folias; este patrón es de gran ayuda para el diagnóstico. Aunque es una entidad que se considera benigna, autolimitada y con buena evolución con tratamiento corticoide, a veces es necesaria la biopsia para diferenciarla de patología tumoral
Acute cerebellitis is one of the main causes of acute cerebellar dysfunction in pediatrics. It can be infectious or occur after infection or vaccination; it is usually viral in origin. It is difficult to diagnose because not all of the clinical signs of cerebellar pathology are present and CSF may be normal. Involvement of a single hemisphere of the cerebellum, hemicerebellitis, is very rare: only three cases were published before 2003 (en castellano dice: hasta 2003; si el año 2003 queda incluso, tiene que ser before 2004). MRI shows unilateral cerebellar edema and enhancement along the folia. This pattern is very helpful in the diagnosis. Although this entity is considered to be a benign, self-limiting disorder that responds well to corticosteroid treatment, it is sometimes necessary to differentiate it from tumors

OBJECTIVES: To show the imaging tests characteristics and differential diagnosis of masses located within the retroperitoneal perirenal area. METHODS: Diagnostic imaging tests (KUB x-ray, ultrasound, helical CT scan with IV contrast) and follow-up in one case of perirenal cell liposarcoma. RESULTS: The study of the surgical specimen after renal tumorectomy in a patient with a solitary kidney resulted in the present diagnosis. CONCLUSIONS: Liposarcoma is a malignant neoplasia derived from fatty tissue. Approximately 13% are located in the retroperitoneal area, and less than 1/3 arise from perinephric fat. We report one case of liposarcoma located in the perirenal cell as an incidental finding during contralateral psoas muscle abscess follow-up in a patient with a solitary kidney after surgery for xanthogranulomatous pyelonephritis. Successive controls during the last year allowed us to evaluate the evolution of this lesion's.

OBJETIVO: Mostrar las características de imagen y el diagnóstico diferencial de las masas localizadas en el área retroperitoneal perirrenal. MÉTODO: Estudio por imagen (RX abdomen, Ecografía, TC helicoidal con contraste intravenoso) diagnóstico y de seguimiento de un caso de liposarcoma de la celda perirrenal. RESULTADO: El estudio de la pieza quirúrgica de la tumerectomía renal en una paciente monorrena dio como resultado el caso presentado. CONCLUSIONES: El liposarcoma es una neoplasia maligna derivada del tejido adiposo; aproximadamente un 13 por ciento se localiza en retroperitoneo, y menos de un tercio se origina en la grasa perinéfrica, constituyendo el liposarcoma perirrenal. Presentamos un caso de liposarcoma localizado en la celda perirrenal como hallazgo incidental del seguimiento de un abceso del psoas contralateral en una paciente monorrena tras cirugía por pielonefritis xantogranulomatosa. Los controles en el último año han permitido valorar la evolución de la imagen de esta lesión (AU)
