Herein, we aimed to underline emphasize that Brown tumors should be kept in mind in the differential diagnosis in patients who are clinically and radiologically considered to have bone metastasis.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Brown tumors are benign, but locally aggressive tumors that may emerge as a rare complication of prolon ged hyperparathyroidism.
📊
Key Findings & Data:Brown tumors show increased metabolic activity on F-18 FDG-PET/CT just as metastatic bone lesions.In this study, we present a patient who underwent PET/CT to seek a primary focus with the presumed diagnosis of multiple bone metastasis, and Brown tumor was suspected because no primary focus was detected on imaging and increased FDG uptake was seen in parathyroid locations, and the diagnosis was confirmed with further investigations.
💡
Conclusion & Impact:Herein, we aimed to underline emphasize that Brown tumors should be kept in mind in the differential diagnosis in patients who are clinically and radiologically considered to have bone metastasis.

Abstract

Brown tumors are benign, but locally aggressive tumors that may emerge as a rare complication of prolon ged hyperparathyroidism. They may be clinically and radiologically confused with bone metastases. Brown tumors show increased metabolic activity on F-18 FDG-PET/CT just as metastatic bone lesions.In this study, we present a patient who underwent PET/CT to seek a primary focus with the presumed diagnosis of multiple bone metastasis, and Brown tumor was suspected because no primary focus was detected on imaging and increased FDG uptake was seen in parathyroid locations, and the diagnosis was confirmed with further investigations. Herein, we aimed to underline emphasize that Brown tumors should be kept in mind in the differential diagnosis in patients who are clinically and radiologically considered to have bone metastasis.

Özet

Brown tümörler uzun süreli hiperparatiroidinin nadir bir komplikasyonu olarak ortaya çıkabilen, benign ancak lokal agresif seyreden tümörlerdir. Klinik ve radyolojik olarak kemik metastazları ile karışabilirler. F-18 FDG PET/CT’de Brown tümörler tıpkı metastatik kemik lezyonları gibi artmış metabolik aktivite gösterirler. Çalışmamızda multiple kemik metastazı ön tanısı ile primer odak aramak için PET/CT çekilen, görüntülerde primer odak saptanmayıp paratiroid lojlarında artmış FDG tutulumu görülmesi nedeni ile Brown tümörden şüphelenilen ve ileri tetkiklerle tanısı doğrulanan bir hasta sunulmuştur. Bu olgu sunumu ile klinik ve radyolojik olarak kemik metastazı düşünülen hastalarda Brown tümörünün de ayırıcı tanıda akılda tutulması gerektiğini vurgulamayı amaçladık.
