The CT diagnosis of rhabdomyosarcoma in children / 中国医师进修杂志

ABSTRACT

Objective To study the performance of children rhabdomyosarcoma (RMS) in CT examation. Methods Twenty-four cases clinical and CT data of RMS which were confirmed by pathology were analyzed retrospectively. Results In head and neck RMS (3 cases), the performance were well-circumscribed soft tissue with uniformity density which were obviously improved after enhancement and showed no invasion to the adjacent bone. In trunk limbs RMS (8 cases), the performance were well-circumscribed soft tissue of many different sizes with uniformity density and mild to moderate uniform(or non-uniform) enhancemen,and the invasion to the adjacent bone was not obvious. In peritoneum and retroperitoneum RMS (6 cases), 5 cases showed non-uniformity isodensity or slightly low density with non-uniformly enhancement and without retroperitoneal lymph node metastasis. The mesenteric (1 case) showed low uniformity density mass and non-uniformly bar enhancement. In urogenital system RMS (7 cases), 2 cases located in the bladder, and 4 cases respectively 1ocated in the vagina, scrotum, testicles and perineum. The performances were uniformity density soft tissue mass like nodular with moderate uniform enhancement. One case located in posterior urethral, whose performance was cystic and solid mass. The cystic part had no enhancement, and the solid part had obviously uniform enhancement. Conclusion The characteristic performance about children RMS is different along with the different parts and age in CT, which has important value for early diagnosis.
