OBJECTIVE: The aims of this review are to describe the main characteristics for the CT diagnosis of isolated caecal ischaemia (ICA) and give details of the differential diagnosis with other conditions with a similar clinical picture.
MATERIAL AND METHODS: A retrospective study was conducted to review the CT findings of 4 patients diagnosed with ICA in our hospital. The parameters recorded to analyse their characteristics in the CT were: maximum thickness of the caecum wall, the appearance of the peri-caecum fat, presence of free fluid, signs of caecal or portal pneumatosis, the appearance of the caecal appendix, and general signs of the presence of vasculopathy.
RESULTS: In all cases it was recorded that there was a thickening of the walls of the blind loop with an abrupt transition between the caecal wall and the walls of the ascending colon wall. In all cases the caecal thickening had a characteristic image in the central area. Signs of caecal pneumatosis were observed in two cases. All of them had an appendix with normal characteristics.
CONCLUSIONS: The combination of caecal wall thickening with oedematous characteristics, with no changes in the appendix, ileum and colon, suggest the diagnosis of caecal ischaemia, particularly with the presence of pneumatosis.
