Abstract:
:Hepatic fungal infection is a frequent complication in patients receiving intensive chemotherapy for acute leukaemia. Hepatic lesions may be detected using computerised tomographic (CT) scans, but there is no standardised CT protocol for the diagnosis and follow-up of hepatic fungal infection. We therefore retrospectively analysed the number and the volume of hepatic fungal lesions in 24 CT of 20 consecutive patients treated for acute leukaemia during late-arterial and porto-venous phase. The mean number of lesions per patient was 31 (range: 3-105) in the late-arterial and 26 (3-81) in the porto-venous CT (P = 0.026). The mean total volume of all lesions was 6.45 ml in the late-arterial and 4.07 ml in the porto-venous CT representing a 1.6fold difference between the two CT scans (P = 0.008). The total volume of the lesions negatively correlated to the absolute contrast difference between liver parenchyma and liver vein (Pearson correlation, r = -0.62; P = 0.002). In conclusion, the late-arterial CT provides a superior distinction of hepatic lesions due to a delayed perfusion of the outer rim of the fungal lesions resulting in an extended visibility. The late-arterial CT is superior to the porto-venous CT for initial diagnosis and follow-up of hepatic fungal infection.
