Discoveries in the Ultrasound Jungle 🌴

Examine the following ultrasound images labeled A, B, and C. 

Based on your observations, how would you describe your findings and what would be the most probable diagnosis based on these images only? Make your diagnosis and then check for the answer!

And here is the correct answer!

What are the most probably diagnoses?

Click here for the answer!

Image A) This ultrasound image shows a diffusely heterogeneous thyroid gland. The parenchyma appears hypoechoic with coarse echotexture. What is the most likely diagnosis based on this ultrasound appearance?
👉 Hashimoto's Thyroiditis

Image B) This ultrasound image depicts an enlarged thyroid gland with multiple confluent nodules of varying size. They appear as heterogeneous masses within the thyroid tissue. The nodules also have cystic components. What condition is illustrated in this ultrasound image?
👉 (Multi)nodular Goiter

Image C) This ultrasound image shows a well-circumscribed, oval-shaped structure in the thyroid region. The structure has a hypoechoic cortex and a central echogenic hilum, typical of a lymph node. What is the structure shown in this ultrasound image?
👉 Lymph Node in the Thyroid Region

OMG! What is this in the heart? 😱

A glimpse inside the heart. Something enters. Can you tell what it is? Do you need to worry?

The correct answer is B: Needle.

What you saw wasn’t a mystery – it was precision at work.

Lost in the apex – what’s your next move?

You’re deep in the apical view, but the landscape looks unfamiliar. The apex doesn’t behave the way it should – compact, quiet, almost hiding something. In the jungle of ultrasound, some findings don’t roar – they whisper. 🤫

But what should catch your attention? Sometimes, key findings are hidden deep in the shadows. You’re the guide now: which imaging step will lead you out of the thicket and closer to the truth? 👀

  • What would you do? *

And here is the correct answer!

What would you do next?

Click here for the answer!

The correct answer is B: Contrast-enhanced echocardiography.

Apical HCM often evades detection on standard 2D imaging due to poor apical definition. A contrast study outlines the true cavity shape – the classic “spade-like” configuration that confirms the diagnosis. This subtle but crucial finding reminds us that even in familiar views, pathology can remain hidden. In the jungle of cardiac imaging, contrast is often the torch that reveals the path.

Caught in the echo jungle: a rare 3rd papillary muscle!

 Even in the heart’s jungle, some things hide well.

This rare variant shows a third papillary muscle – a reminder that papillary anatomy can vary in size, length, location, and even number.

What you spotted is subtle – and rare.

This case shows a third papillary muscle in the left ventricle, an uncommon anatomical variant. 🧠 The papillary muscles can vary greatly in: Location, Size, Length; and, as seen here – even number. While often benign, such variations can sometimes be linked to mitral valve abnormalities or LVOT dynamics.

Always worth a closer look!

A deadly embolism in a 20-year-old?! You won’t believe what we found…

A 20-year-old male from rural Romania presented with acute peripheral limb ischemia due to complete occlusion of the right femoropopliteal artery. His mental status was altered – he showed lethargy and very slow responsiveness.

A thrombectomy was performed. The extracted material did not resemble typical thromboembolic debris; instead, it was made up of amorphous, lamellar, shell-like structures. Was this really a classic thromboembolic event? These findings together with the young age and the absence of any risk factors prompted an echo exam – look at these incredible images... What differential diagnoses come to your mind?

  • What differential diagnoses come to mind? *

And here is the correct answer!

Which differential diagnoses come to your mind? 👇

Click here for the answer!

The correct answer is B!

The patient had a primary cardiac manifestation of Echinococcus cysticus.

Treatment: Antihelminthic therapy with albendazole and praziquantel & surgical removal of the cardiac hydatide cyst + mitral valve replacement.

But unfortunately, the patient's condition further deteriorated... A follow up post is coming soon!

Which pathology does the “snake sign” describe? 🐍

Are you good with reptiles?

  • Which pathology does the snake sign describe? *

And here is the correct answer!

Which pathology does the “snake sign” describe? 🐍

Click here for the answer!

The correct answer is C!

Thrombus in the right atrium originating from the IVC or femoral veins!


The snake sign or snake-like thrombus is clearly a frightening pathology. Its name however comes from its appearance, which resembles that of a snake. The thrombus forms in the veins of the lower extremity or IVC and therefore has the shape of a snake. If it dislodges it will cause pulmonary embolism (or even worse paradox embolism). Along its path it is often caught in the right heart where it can be detected with echo. The following image shows such a snake thrombus in a transthoracic subcostal view.

More MSK ultrasound quizzes

🌞 Running wild this summer? Don’t let this pathology slow you down!

🔍 Check out this MSK ultrasound image highlighting a pathology often causing lateral knee pain in runners and cyclists. MSK ultrasound allows straight-forward diagnosis  to make your patients fit again for a sporty summer. 

📌 Of course, proper MSK ultrasound requires scanning in two planes – but here we’ve only got the still image of a long-axis view of the structure in question. Based on the sonoanatomy and visible pathology, you should be able to make a well-informed guess... 👀

And here is the correct answer!

What's the most likely diagnosis? 👇

Correct answer and explanation

The correct answer is B!

This long-axis MSK ultrasound image shows thickening and hypoechoic fluid collection in the area of the iliotibial band (ITB) as it passes over the lateral femoral condyle – a hallmark of ITB friction syndrome, commonly also called "runner’s knee."

🔍The ITB does not appear thickened but here is hypoechoic fluid/ edema deep to the band.

The location (lateral knee) and the sonopathologic caracteristics point to ITB pathology, not a medial meniscal tear (A) or a posterior popliteal cyst (C)!

Don't get lost in the jungle of intestinal ultrasound!

A 36-year-old man came in with abdominal pain in the right lower quadrant, and he has no fever. Can you crack the case?

  • Which landmark do you use when scanning this area? *

And here is the correct answer!

Which landmark do you use when scanning this area?

Click here for the answer!

The correct answer is E) All of the above!

All of the above are correct! When scanning for the appendix, key landmarks like the iliac vessels, psoas muscle, terminal ileum, and ascending colon are crucial for orientation. However, finding a healthy appendix is tough, with only 30% being locatable due to its elusive nature in ultrasound scans.
