Ultrasound-guided core-needle biopsy of extra-ocular orbital lesions

摘要: To evaluate the diagnostic yield of ultrasound-guided core-needle biopsy extra-ocular orbital lesions. Fifty-five patients with monolateral exophthalmos prospectively underwent computed tomography (CT) to investigate presence an mass (n = 25). Excluding benign lesions (n = 7) and in whom CT revealed unknown primitive malignancy (n = 5), 13 (7 male, 6 female; mean age 62 ± 16 years) ultrasound. Lesion appearance (echotexture, power Doppler vascularisation), size, position respect cone globe were recorded. Ultrasound-guided biopsies performed (automatic, n = 9; semi-automatic 18-G needle, n = 4). Sample adequacy complication rate Ultrasound demonstrated hypoechoic mild vascularity, that completely or partially extra-conal (n = 6), located laterally (n = 8) posteriorly (n = 5) globe. Mean size was 3.25 cm. All yielded adequate material for histological immunohistochemical analysis (nine non-Hodgkin’s lymphomas, two adenocarcinomas, one lymphoid hyperplasia, inflammatory pseudotumour). Complications included cutaneous eyelid haematoma (n = 3) retro-bulbar (n = 1), treated conservatively resolved at 10-day follow-up. No immediate delayed vision reduction reported. is feasible accurate, being free from long-term complications. This procedure provided 100 % samples achieve final diagnosis. • seems accurate. In this series it a diagnosis 13/13 cases. It appears complications. provides specimen. should represent valuable alternative surgical biopsy.
