Bocio amiloide: A propósito de un caso Amyloid goiter: A case report

El bocio amiloide es una manifestación atípica de la amiloidosis. Se presenta el caso de una paciente con antecedentes de artritis reumatoide y aumento de volumen subagudo de la glándula tiroidea con hallazgos ultrasonográficos y por tomografía computada compatible con bocio amiloide. Se exponen sus características radiológicas, objeto de la presente comunicación.Amyloid goiter is an atypical manifestation of amyloidosis. A case of a patient with rheumatoid arthritis history and sub-acute thyroid gland volume significantly increased is presented. Ultrasonographic and computed tomography findings were compatible with amyloid goiter. The aim of this study is to describe its radiologic features

Tratamiento mediante punción guiada por TC de un meningocele intrasacro oculto doloroso: Caso clínico y revisión de la literatura

Case reports: We report a 43-year old patient with a history of disabling pain sacrum 8/10 on the VAS of 8 months. No sensory disturbances were noted or loss of bowel control. Consultation conducted in multiple hospitals. She underwent a computed tomography (CT) lumbar that highlighted a hemangioma in L5, a magnetic resonance imaging (MRI) of the pelvis which showed muscle breakdown grade I of the left maximus gluteus, and a cystic lesion in the sacrum, which was interpreted as a Tarlov cyst. She received analgesic and anti-inflammatory treatment with no improvement. She also goes through two facet blocks and even a lock in the left piriformis, all without results. In our center we practised a lumbosacral MRI which highlighted a cystic lesion localized in central and right lateral sacral spinal canal at the level of S2-S3 transition. It was high signal on T2 and low signal on T1. Discussion: According to Nabors classification, this lesion corresponds to a hidden intrasacro meningocele. The hidden intrasacro meningocele (extradural meningeal cyst type classification LB Nabors) is a rare entity that usually develops between the third and fourth decade of life, as an insidious clinical lower extremity pain, with or without radicular symptoms, bowel dysfunction and sensory disturbances. The usual treatment of these lesions is surgical intervention. In our case puncture and evacuation guided by CT of the sacral cyst was performed, yielding about 2 cc of a sero-hematic fluid. The postoperative course was a remarkable improvement, and the sacral pain happened to be 3/10 on the VAS. In the literature that we have reviewed, this is the first case in which a hidden painful intrasacro meningocele is evacuated by CT-guided puncture.Casos clínicos: Presentamos una paciente de 43 años con historia clínica de dolor sacro incapacitante 8/10 en la escala de EVA de 8 meses de evolución. No se apreciaban alteraciones sensitivas ni pérdida del control de esfínteres. Realizó consulta en múltiples hospitales. Se le practicaron una tomografía computadorizada (TC) lumbar que puso de relieve un hemangioma en L5, una resonancia magnética (RM) de pelvis en la que se evidenció rotura muscular grado I del glúteo mayor izquierdo y una lesión quística en el sacro que se interpretó como quiste de Tarlov. Recibió tratamiento analgésico y antiinflamatorio sin mejoría. Se le realizaron dos bloqueos facetarios e incluso un bloqueo del músculo piriforme izquierdo, todo ello sin resultados. En nuestro centro se practicó una RM lumbo-sacra que puso de relieve la lesión quística de localización central y lateral derecha en canal espinal sacro a la altura de la transición S2-S3. Era de alta señal en T2 y de baja señal en T1. Según la clasificación de Nabors correspondía a un meningocele intrasacro oculto. Discusión: El meningocele intrasacro oculto (quiste meníngeo extradural tipo lB de la clasificación de Nabors) es una entidad poco frecuente que se presenta generalmente entre la tercera y cuarta década de la vida, como un cuadro clínico insidioso de dolor en extremidades inferiores, con o sin síntomas radiculares, disfunción de esfínteres y alteraciones sensitivas. El tratamiento habitual de este tipo de lesiones es la intervención quirúrgica. En nuestro caso se realizó punción y evacuación del quiste sacro guiado por TC obteniéndose unos 2 cc de un líquido sero-hemático. La evolución posterior fue de mejoría notable del dolor sacro que paso a ser de 3/10 en la escala de EVA. En la revisión de la literatura que hemos efectuado este es el primer caso en que se trata un meningocele intrasacro oculto doloroso mediante punción evacuadora guiada por TC

Procedural approaches and angiographic signs predicting first-pass recanalization in patients treated with mechanical thrombectomy for acute ischaemic stroke

Background: First-pass recanalization via mechanical thrombectomy (MT) has been associated with improved clinical outcome in patients with acute ischaemic stroke. The optimal approach to achieve first-pass effect (FPE) remains unclear. No study has evaluated angiographic features associated with the achievement of FPE. We aimed to determine the procedural approaches and angiographic signs that may predict FPE. Methods: We performed a prospective, multi-centre, observational study of FPE in patients with anterior circulation stroke treated with MT between February and June 2017. MTs were performed using different devices, deployment manoeuvres (standard versus \u2018Push and Fluff\u2019 technique), proximal balloon guide catheter (PBGC), distal aspiration catheter (DAC) or both. The angiographic clot protrusion sign (ACPS) was recorded. Completed FPE (cFPE) was defined as a modified thrombolysis in cerebral infarction score of 2c\u20133. Associations were sought between cFPE and procedural approaches and angiographic signs. Results: A total of 193 patients were included. cFPE was achieved in 74 (38.3%) patients. The use of the push and fluff technique (odds ratio (OR) 3.45, 95% confidence interval (CI): 1.28\u20139.29, p = 0.010), PBGC (OR 3.81, 95% CI: 1.41\u201310.22, p = 0.008) and ACPS (OR 4.71, 95% CI: 1.78\u201312.44, p = 0.002) were independently associated with cFPE. Concurrence of these three variables led to cFPE in 82 vs 35% of the remaining cases (p = 0.002). Conclusions: The concurrence of the PBGC, the push and fluff technique, and the ACPS was associated with the highest rates of cFPE. Appropriate selection of the thrombectomy device and deployment technique may lead to better procedural outcomes. ACPS could be used to assess clot integration strategies in future trials
