Repercussões clínicas e radiológicas do neurofibroma plexiforme na região pélvica

Abstract

The authors report the case of a plexiform neurofibroma located in the pelvis, affecting the bladder, prostate and spine (lumbar/sacral), followed-up for three years and six months. Surgical removal was contraindicated and the patient underwent biannual clinical and radiological follow-up that did not demonstrate any tumor increase. The clinical manifestations of neurofibromatosis type 1 are variable, and the medical team should be attentive to further investigations, considering possible unexpected rare findings. Large pelvic masses may correspond to plexiform neurofibromas, so the diagnostic hypothesis of neurofibromatosis should be taken into consideration.

Plexiform neurofibroma masquerading as a seminal vesicle mass: A case review

“…5 The majority of these lesions are asymptomatic, and symptoms, if present, are due to the mass effect on adjacent structures or malignant infiltration, which is seen in up to 30% cases of pelvic PNFs. 6 The radiological features of neurofibromas are distinct. On US, neurofibromas present as a hypoechoic mass along the distribution of peripheral nerves.…”

Neurofibroma Plexiforme Vesical em Portador de Neurofibromatose: Relato de caso

“…Ante a suspeita de NFP, a combinação de métodos de imagem (ultrassonografia, tomografia computadorizada e ressonância magnética) é capaz de demonstrá-los [16][17][18] . A ressonância magnética é o método de escolha para o diagnóstico de neurofibromas plexiformes, assim como para distinção da natureza e extensão tumoral 19,20 .…”
