US and CR findings in splenic focal lesions in AIDS

Abstract

Purpose: To evaluate the role of US and CT in focal splenic lesions in AIDS patients in relation to etiology.

Material and Methods: A total of 66 patients with AIDS and focal splenic lesions were examined with sonography. CT with administration of contrast medium was performed in 12 cases.

Results: Of the focal splenic lesions, 67% were correlated with an infective pathology with prevalence of Mycobacteria tuberculosis (75%), 26% were neoplastic and 6% splenic infarcts. The lesions were hypoechoic in 60% of the cases, while 10% were hypoanechoic and 1% anechoic. At CT, all lesions appeared hypodense, even after i.v. administration of contrast medium.

Conclusion: The combination of echographic reports and clinical and laboratory data allows for a diagnosis that can be confirmed, and making a decision for effective therapy of AIDS is possible. CT does not provide any additional information.
