[CT-guided course-punch biopsy of the adrenals. The indications, technic and results].

Adrenal lesions exceeding 1.5 cm diameter were biopsied with a Tru-Cut needle (G 14) under CT guidance for histologic evaluation in 61 patients. Using CT for guidance, special techniques for safe access to the adrenals are described. Large-bore biopsy yielded a sensitivity of 100% and a specificity of 97.4%. Diagnostic accuracy was 98.3%. No significant complications occurred. In comparison to the results of FNA reported in the literature, large-bore biopsy of adrenal lesions improves the rate of adequate material and the histopathologic differentiation without increase of complications.
