Sixty-three patients with splenic cysts, multiple in 7 cases, were reviewed. Only 3 patients had a history of previous abdominal trauma. The cysts ranged in size from less than 1 cm to 15 cm. They were anechoic in 40 patients, hypoechoic in 16, isoechoic in 4, mixed in one, and in 2 cases the echogenicity could not be assessed due to thick marginal calcifications. The echogenic cysts were larger than the anechoic ones and frequently calcified, and the findings at surgery, fine-needle aspiration biopsy and follow-up suggested the echogenicity to be related to a fresh or previous episode of intracystic hemorrhage. Initially, surgical treatment was undertaken on 10 patients, electively in 9 cases and due to cyst rupture in one. At follow-up (n = 37), the size of the cyst had increased markedly over several years in only 2 patients, necessitating delayed surgery in one. Routine follow-up of asymptomatic splenic cysts was of no clinical value.
对63例脾囊肿患者进行了回顾性研究，其中7例为多发性囊肿。只有3例患者有腹部外伤史。囊肿大小从小于1厘米到15厘米不等。40例患者的囊肿为无回声，16例为低回声，4例为等回声，1例为混合回声，2例因边缘钙化厚无法评估回声。有回声的囊肿比无回声的囊肿大，且常伴有钙化，手术、细针穿刺活检及随访结果提示，回声与囊内新鲜或既往出血有关。最初，10例患者接受了手术治疗，其中9例为择期手术，1例因囊肿破裂手术。随访（n = 37）时，仅2例患者的囊肿在数年内明显增大，其中1例需要延迟手术。对无症状脾囊肿进行常规随访无临床价值。
