To the Editor, Image-guided splenic interventions are rarely performed due to concern for risk of hemorrhage leading to complications with risks often outweighing the benefits. The major complication rate for large-core (14G) splenic biopsy has been reported as high as 13%[1] likely due to the highly vascular nature of the organ. Smaller-gauge core needle biopsy decreases this rate of major complications to approximately\2%[2]. Although core needle biopsy has the highest tissue and diagnostic yield, fine needles (22G) have fewer bleeding complications [3]. Many cystic or solid splenic lesions cannot be characterized well with imaging alone. For these patients, biopsy may be very useful, especially in malignant diseases that can have diffuse or localized splenic involvement like Hodgkin and non-Hodgkin lymphoma [2]. A 38-year-old female with history of Li-Fraumeni syndrome developed an enlarging 3-cm splenic lesion with high signal intensity on T2-weighted MRI. RF ablation of the needle track was performed without an RFA probe, with a small-gauge active uninsulated 25G stylet (Covidien/Radionics) placed inside a 22G Chiba needle, and then placed inside the outer coaxial 19G cannula, with this all inside an insulating 18G Angiocath sheath (with the hub cut off). This RFA stylet is commonly used for neurolysis and is non-disposable and always used when contained within a larger needle. The tri-axial biopsy ablation system with a grounded thermochromic, tissue-mimicking
