MDCT Evaluation of Hepatic Manifestations in Malignant Hematological Disorders

Objective: The aim of this work was to evaluate Multidetector Computed Tomography (MDCT) findings of hepatic manifestation in common malignant hematological disorders. Materials and Methods: This retrospective study included 300 patients with different types of malignant hematological disorders. They were 119 female and 181 male (mean age, 45.4 year; range, 5-70 years). The most common hematological disorder was Non-Hodgkin lymphoma (NHL) detected in 192/300 (64%) patients and then Hodgkin disease (HD) detected in 40/300 (13.3%) patients. All 300 patients had ultrasonography. Clinical evaluation and laboratory assessment were done for all patients. Whole body and triphasic abdominal CT scanning was performed on 64 MDCT systems. Results: MDCT scanning revealed hepatic affection in 82/192 of NHL. All these 82 cases revealed hepatomegaly and focal lesion detected in 36 cases. As regard Hodgkin disease (HD), hepatomegaly detected in 22/40 cases and focal lesion detected in 8/40 cases. Hepatomegaly detected in 8/14 cases of acute myeloid leukemia (AML) and focal lesion detected in 4/14 cases. In cases of chronic lymphocytic leukemia (CLL), hepatomegaly detected in 6/22 cases with no detection of focal lesion. Conclusion: Hepatic involvement is often observed in several malignant hematological disorders, resulting in abnormalities in liver imaging studies. Malignant hematological disorders must be considered in hepatomegaly and hepatic focal lesions either single or multiple. MDCT is the diagnostic modality of choice for diagnosis and follow up of liver affection in different malignant hematological disorders.
