Abstract(s)
Os leiomiomas são a patologia tumoral ginecológica com maior incidência, apresentando características imagiológicas bem
documentadas na literatura. Dificuldades diagnósticas ocorrem, em regra, com o marcado aumento das dimensões dos leiomiomas resultando em diversos
tipos de degenerescência. De entre estas, a de tipo hialina constitui a mais frequentemente observada, ocorrendo em cerca de 60%
dos casos. As degenerescências de tipo mixóide, quística e hemorrágica são encontradas mais raramente. A presença de edema pode prever o desenvolvimento de fenómenos de degenerescência sendo, no entanto, um achado histopatológico comum, encontrado
em cerca de 50% dos casos de leiomiomas. O diagnóstico diferencial dos leiomiomas inclui a adenomiose, situação clínica que afecta mulheres na fase pré-menopáusica. A
Ressonância Magnética assume especial importância no seu diagnóstico, localização e distinção tendo impacto na orientação da doente ao permitir uma adequada abordagem terapêutica.
Leiomyomas are the most common gynaecologic neoplasms presenting with imaging finding well documented in the literature. Difficult diagnosis may occur when a marked increase in the dimensions of the leiomyomas is present resulting in various types of degeneration. The most common type of degeneration is hyaline degeneration occurring approximately in 60% of the cases. Cystic, myxoid, and red degeneration rarely occur. The presence of oedema can predict the occurrence of degenerative phenomena being a common histopathologic finding, seen in approximately 50% of cases. The differential diagnosis of leiomyomas includes adenomyosis, a clinical situation that affects pre-menopausal women. Magnetic Resonance imaging plays an important role in its diagnosis, location and distinction. Also MRI findings will impact on patient management determining the appropriate treatment options.
