spara0015">Patients with an appendiceal neoplasm from 2004–2014 were identified on a pathology database. Of these, 94 patients were identified and all reviewed for clinical and radiological data. Cases with a preoperative CT scan suggesting acute appendicitis were analysed in consensus by two gastrointestinal (GI) radiologists. The appendix was evaluated for the following morphological parameters: maximal diameter, cystic dilatation, tissue mass and presence of calcification.
spara0020">Thirteen (13.8%) patients with symptoms of acute appendicitis had a preoperative CT scan. The age range was 21–89 with a mean age of 62.6 years. The appendix was not visualised in three patients. CT demonstrated increased appendiceal diameter, cystic dilatation, tissue mass and calcification in five (38.5%), five (38.5%), 1 (7.7 %) and three (23.1%) respectively.
spara0025">CT remains useful in identifying underlying appendiceal tumours in patients with acute appendicitis although a significant proportion of our case series did not demonstrate features to suggest underlying tumour.
