RESUMO
RESUMEN El bloqueo de rama enmascarado es una forma poco frecuente de bloqueo bifascicular de la cual se desconoce su mecanismo con exactitud. Es más frecuente encontrarlo en pacientes de edad avanzada o aquellos con una cardiopatía estructural como: enfermedad coronaria, hipertrofia ventricular, miocardiopatías, miocarditis chagásica y degeneración idiopática del sistema excitoconductor del corazón. Su diagnóstico electrocardiográfico se obtiene por la presencia de ondas R altas y anchas en V1 (patrón de bloqueo de rama derecha), desviación del eje eléctrico a la izquierda (entre -80 y -120 grados) y una onda S inferior a 1 mm o ausente en DI y aVL. Su presencia denota un factor de mal pronóstico en los pacientes.
ABSTRACT Masquerading bundle branch block is a rare form of bifascicular block, whose exact mechanism is unknown. It is more frequently found in elderly patients or those with structural heart disease such as: coronary artery disease, ventricular hypertrophy, cardiomyopathies, Chagas myocarditis and idiopathic degeneration of the cardiac conduction system. Its electrocardiographic diagnosis is obtained by the presence of high and wide R waves in V1 (right bundle branch block pattern), left axis deviation (between -80 and -120 degrees) and an S wave of less than 1 mm or absent in I and aVL leads. Its presence denotes a poor prognostic factor in patients.

Bloqueio de Ramo , DiagnósticoRESUMO
Angioleiomyoma is a rare benign tumour of uterus. We are presenting an unusual case of 45-year-old female with 11 kg giant angioleiomyoma of uterus which was masquerading as ovarian tumour on imaging. Exploratory laparotomy was done which was suggestive of huge lobulated mass arising from the uterus. Hysterectomy with bilateral salpingo-oophorectomy was done. Histopathological examination of specimen was suggestive of uterine subserosal and broad ligament angioleiomyoma of cavernous type. This case is being reported because of its rarity and challenges in diagnosis and management.
