The review identified a total of 106 biopsies during the 7 month period. Of these, 8 (7.5%) were non-diagnostic, leading to a diagnostic yield of 92.5%. Of the non-diagnostic biopsies, there were: 4 lymph nodes, 1 lung, 1 mediastinal mass, 1 thyroid and 1 bone biopsy. Based on review of the pathology reports, non-diagnostic biopsies were the result of either inadequate sample amount (3 cases) or biopsy of surrounding normal tissues i.e., missed biopsies (5 cases). Although there were inconsistencies in documentation and limited sample size, possible contributing factors to non-diagnostic biopsies included: use of FNA rather than core biopsy, small lesions, mobile lesions, lesions what were difficult to penetrate with needles, lesions that were difficult to localise on imaging and lesions that were technically difficult to access percutaneously.
