Percutaneous lung biopsy had been described in the nineteenth century by Leyden, but image- guided needle chest biopsy only gained widespread acceptance in the 1970s. Currently, tissue sampling of a thoracic lesion is indicated when the diagnosis cannot be obtained by the non-invasive techniques and cytological diagnosis will modify the stage of the disease or influence the therapeutic strategy. Cytology obtained by small-gauge needle aspiration biopsy confirms the nature of the lesion in 80 - 95% of cases and carry a low incidence of major complications. The purpose of this report was to provide information on our first experience with CT-guided biopsy and show that with some innovativeness much can be achieve with limited resources and good team work. We performed a CT of the thorax using appropriately placed improvised metal markers, which determined the optimal cutaneous entry point. We then re-checked the location of the lesion scanning intermittently at 5mm slice thickness; we marked the entry point with a pen and cleaned the surface with methylated spirit. A local anaesthetic was subcutaneously injected around marked area. We used a 21G aspiration needle to obtain cytology sample then 18G Trucut biopsy needle to obtain histology specimen. The length of the needle was chosen based on predetermined distance of the target lesion from the skin estimated from the CT images. Our patient was a 51-year-old Nigerian female with a peripherally located nodule in the posterior aspect of the right lung. She had CT-guided biopsy of the nodule. The procedure was well tolerated with no complication of pneumothorax. The histology report provided the basis for treatment regimen. Our experience indicates that percutaneous transthoracic CT-guided needle biopsy is feasible and a safe procedure in our hospital for evaluation of undetermined lung lesions.
