🧵 Adrenal Lesion Evaluation:
3 Key Diagnostic Features 🔍

📸 CT is the go-to modality for the evaluation of adrenal lesions! Let’s dive into some details that can help us make an accurate diagnosis👇

#Radiology #AdrenalGland 🟢Key Feature 1: Non-Contrast Density

💡 The non-contrast density is a key parameter to begin distinguishing between different types of adrenal lesions
A threshold of 10 HU is fundamental for differentiating adenomas (<10 HU) from other adrenal lesions (tipically >10 HU)✅

#juniorradres and all those starting to see chest x-rays 🫁☢️ Here an anatomical guide to get you started! This is a key study in thoracic imaging, often a little overlooked by our generation. Practice makes perfect🤓... Let's get started! 🧵👇🏻

Mediastinal lines
🟡 Paratracheal lines
🟣 Main pulmonary artery line
🟢 Pleuroazigoesophageal line
🟠 Aorta
🔵 SVC
RA and LV (Lightblue)

Up for a Sunday tweetorial? 🤓

If you see this multicystic lung lesion 🫁 in the posterobasal region of the lower lobes in a young patient 🚹🚺with no pathological history, two differential diagnoses should be considered: CPAM vs pulmonary sequestration ✅
#radiology #FOAMrad These two congenital lesions are areas of aberrant lung parenchyma not connected to the central airways. Their main difference is the arterial supply. That's why the first thing to do is try to identify the systemic artery that supplies the lesion 🟣(most often an aortic branch)
