Giant Abdominal Aortic Aneurysm in Bone Scan

Key Findings & Data:We present a rare case who presented with back pain and underwent a 3-phase bone scan with Tc-99m methylene diphosphonate, which revealed a giant AAA on blood-flow and blood-pool phases in addition to bone metastases.

💡

Conclusion & Impact:The initial two phases of a 3-phase bone scintigraphy are decisive to identify vascular pathologies that may be life-threatening, if left untreated.

🔬Design:Lab & Field Experiment

📍Scope:Comprehensive Sample

⚙️Variables:Domain Parameters

Abstract

Abdominal aortic aneurysm (AAA) may be incidentally detected in three-phased bone scintigraphy. AAA should be diagnosed prior to the development of symptoms to perform elective repair surgery. We present a rare case who presented with back pain and underwent a 3-phase bone scan with Tc-99m methylene diphosphonate, which revealed a giant AAA on blood-flow and blood-pool phases in addition to bone metastases. F-18-fluorodeoxyglucose positron emission tomography/computed tomography (CT) identified hypermetabolic liver, lung, and bone lesions, and CT component of the study confirmed the diagnosis of AAA with a maximum diameter of 92 mm. The initial two phases of a 3-phase bone scintigraphy are decisive to identify vascular pathologies that may be life-threatening, if left untreated.

Özet

Abdominal aort anevrizması (AAA), 3-fazlı kemik sintigrafisinde insidental olarak saptanabilmektedir. Semptomlar ortaya çıkmadan elektif cerrahi uygulanabilmesi için, AAA tanısının doğru olarak konulması önemlidir. Burada, sırt ağrısı şikayeti ile başvuran bir olguda, Tc-99m metilen difosfonat 3-fazlı kemik sintigrafisinde kemik metastazlarının yanı sıra kan akımı ve kan havuzu fazlarında dev AAA saptanan nadir bir olgu sunuyoruz. F-18 florodeoksiglukoz pozitron emisyon tomografi/bilgisayarlı tomografide (BT) hipermetabolik karaciğer, akciğer ve kemik lezyonları görüldü ve çalışmanın BT bileşeninde maksimum çapı 92 mm olan AAA tanısı doğrulandı. 3-fazlı kemik sintigrafisinde, tedavi edilmediği takdirde yaşamı tehdit edebilecek vasküler patolojileri tanımlamak için ilk iki faz belirleyicidir.
