Patient
male, 43 year(s)
 
 
  • Figure 1
    Initial unenhanced CT
     

    Bilaterally, moderate pleural effusion and perihilar lung infiltrates are present and consistent with opportunistic infection.

     
    Area of Interest: Lung; Imaging Technique: CT; Special Focus: AIDS;

    Large hyperattenuating (60-65 HU) collection medially compresses the right renal parenchyma and laterally bulges the renal capsule. Absent hydronephrosis bilaterally.

     
    Area of Interest: Kidney; Imaging Technique: CT; Special Focus: AIDS;

    Large hyperattenuating collection with some heterogeneity in its caudalmost portion, medially compressing the right renal parenchyma and laterally bulging the renal capsule.

     
    Area of Interest: Kidney; Imaging Technique: CT; Special Focus: AIDS;

    Detailed view confirms the subcapsular location of the right perinephric haematoma.

     
    Area of Interest: Kidney; Imaging Technique: CT; Special Focus: AIDS;
     
     
  • Figure 2
    Unenhanced and contrast-enhanced follow-up CT
     

    Seven days later, the subcapsular renal haematoma shows unchanged size, attenuation and mass effect.

     
    Area of Interest: Kidney; Imaging Technique: CT; Special Focus: AIDS;

    Following iv contrast administration, no enhancing tissue or active contrast extravasation are detected. Compressed right kidney shows faint parenchymal enhancement compared to left one.

     
    Area of Interest: Kidney; Imaging Technique: CT; Special Focus: AIDS;

    Following iv contrast administration, no enhancing tissue or active contrast extravasation are detected. Caudally, haematoma focally indents the renal parenchyma.
