Purpose : To evaluate the CT findings of perihepatic tuberculous abscesses. Materials and Methods : The CT scans of 11 patients (6 females and 5 males) with 14 pathologically proven perihepatic tuberculous abscess were retrospectively evaluated in terms of the morphological characteristics of the abscesses and changes in other abdominal organs and at other sites. Results : A total of 14 absceses were noted in 11 patients. Six (43%) were in the right subphrenic space, three(21%) in the right perihepatic space, three (21 %) in the left subphrenic space, and two (14%) in the left perihepatic space. The right side was predominant. The abscesses ranged in size from 1 to 10 (mean, 5) cm in diameter, with a wall thickness of 2 - 7 (mean, 3) mm. Of the 14 abscesses, 13 were oval, and one spherical. CT findings were as follows: a smooth abscess margin with even wall thickness in seven of the eleven patients (64%); calcification of the wall in two (18%) ; internal septa in seven (64 %) ; localized fluid collection in nine (82%) ; lymphadenopathy in five (45 %) ; and peritoneal enhancement in seven (64%). Lesions suggesting tu-berculous infection coexisted at other sites in eight patients. These included the lung in six patients (55%) , the neck in three (27 %), an axilla in two (18 %), the liver in two (18 %), the spleen in one (9 %), and the gastroin-testinal tract in one (9%). Conclusion : CT scanning is useful for establishing the diagnosis of perihepatic tuberculous abscesses by eval-uating the morphological characteristics of the mass and by observing changes in other abdominal organs and at other sites.
