Nonparasitic splenic cysts. Ultrasonographic features and follow-up.
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.
