RESUMEN
PURPOSE: To evaluate the safety and efficacy of CT fluoroscopy-guided percutaneous cryoablation (PCA) after lipiodol marking and embolization (LME) in patients with renal cell carcinoma (RCC). MATERIAL AND METHODS: This study included 29 patients (18 men, 11 women; mean age 69 years, range 22-89 years) with 42 RCCs. They underwent CT fluoroscopy-guided PCA after LME between March 2016 and March 2020. The mean tumor diameter was 21 mm (range 7-50 mm). LME was performed with lipiodol and gelatin particles. PCA was considered successful when the ice ball encapsulated the entire tumor and the margin was sufficient on post-ablation CT scans. RESULTS: LME was successfully performed in 39 of 40 tumors (97.5%). PCA after LME was successful in all 39 of 39 tumors (100%). During the follow-up period (mean 13.9 ± 12.1 months), one of the 39 tumors (2.6%) developed local tumor progression. A significant complication (reversible hypertensive crisis) was encountered in only one of 37 (2.7%) procedures. The mean eGFR was 64.2 ± 26.8 before and 63.3 ± 26.4 after PCA (p = .44). CONCLUSION: LME using iodized oil and gelatin particles to improve visualization of the RCC facilitated tumor localization on unenhanced CT images. PCA after LME might be a safe and effective for treatment in patients with RCC.

A 71-year-old Japanese male was diagnosed with essential thrombocythemia (ET) with the JAK2 V617F mutation variation, in April 2011. He was mainly treated with hydroxyurea following which the number of platelets was maintained within the normal limit. At age 80, he was hospitalized due to cardiac tamponade. Computed tomography showed no evidence of tumor masses or lymphadenopathy. Pericardial drainage was performed, and cytopathologic examination of the fluid revealed atypical lymphoid cells consistent with an effusion lymphoma of B cell lineage. The pericardial effusion was completely drained, and complete remission was achieved. Ultimately, the patient was diagnosed with primary effusion lymphoma-like lymphoma (PEL-LL). To the best of our knowledge, this is the first report of PEL-LL following ET.
