title: CT guided transgluteal fine needle aspiration biopsy.
abstract: CT is a suitable method for evaluation of local recurrence of rectal carcinoma after abdomino-perineal resection, as the presence of a soft tissue mass in the presacral area may be due to either residual changes from the previous surgery, or recurring disease. CT guided fine needle aspiration biopsy with a transgluteal approach was a relatively simple and fast procedure for obtaining cytological proof on the nature of the lesion in 7 out of 9 patients.
