Computed tomography and ultrasound appearance of bladder malacoplakia.

The computed tomography and ultrasound findings of two patients with malacoplakia of the bladder, both at the time of initial diagnosis and following response to treatment, are presented. Because bladder wall involvement is demonstrated by these modalities in female patients with repeated episodes of urinary tract infection, this entity should be entertained in the differential diagnosis.

Computed tomography and ultrasound appearance of liver disease in secondary syphilis.

Liver disease occurring as a manifestation of secondary syphilis is unusual, and this association is not readily recognized or considered in the differential diagnosis of obscure hepatic disease, thereby causing delay in treatment. We describe a case of liver involvement in secondary syphilis with computed-tomography and ultrasound findings. This entity should be considered in patients with hepatomegaly coexisting with the clinical stigmata of secondary syphilis, as treatment with penicillin results in rapid improvement in both the clinical and biochemical findings.
