OBJECTIVE: To analyze the cause of atypical manifestation of @entity157 ( @entity157 ) in triple-phase spiral CT enhanced scan. METHODS: Triple-phase spiral CT scan was performed in 75 @entity1 with @entity157 . The hepatic arterial phase (HAP), portal venous phase ( @entity12468 ) and delayed phase (DP) images were started at 25 to 30 s, 65 to 70 s and 3 tp 5 min after injection of contrast medium. The contrast enhanced patterns of lesion were observed and analyzed. RESULTS: Ninety-two lesions were found in 75 @entity1 . Typical enhanced findings such as hyperdense in HAP and @entity6152 in @entity12468 and DP was found in 60 of 92 lesions. Atypical enhanced findings were observed in the other 32 lesions. Fourteen of 32 atypical enhanced lesions were hyperdense in HAP and isodense in @entity12468 , of which 8 were seen in liver @entity82 and 3 in @entity1560 . In DP, 10 were @entity6152 and 4 still isodense. Eight of the 32 lesions were hyperdense both in HAP and @entity12468 , of which 6 were seen in @entity1560 . In DP, 3 were isodense and 5 were @entity6152 . Six of 32 lesions were isodense in HAP which became @entity6152 in @entity12468 and DP. Four of 32 lesions were all @entity6152 in HAP, @entity12468 and DP. CONCLUSION: Multiple atypical enhanced manifestations are present by triple-phase spiral CT scan in @entity157 . Pattern of blood supply, scanning technique and pathophysiologic status are usually the cause of these findings.
