| 11 |  Epiglottis in a 5-year-old boy with respiratory distress and drooling. A lateral soft tissue neck radiograph shows a markedly thickened epiglottis (white arrow), which is referred to as the “thumb” sign. The aryepiglottic folds (black arrow) also are thickened.

| 12 |  A 73-year-old patient with active colon cancer and massive pulmonary embolism.
There was a worm-shaped large mobile risky clot in the right atrium (RA), which was very dangerous, especially with right ventricular (RV) dysfunction.
The patient received a half-dose (50 mg) of alteplase.
Follow-up echocardiography showed complete resolution of the RA clot.
The patient was later discharged with alleviated symptoms and some improvement in RV function.

| 13 | The correct answer is Kussmaul sign.
🩺 Explanation
▶️ Kussmaul sign:
- Defined as a paradoxical rise in jugular venous pressure (JVP) during inspiration.
- Normally, inspiration decreases intrathoracic pressure ➔ increases venous return ➔ lowers JVP.
- In conditions like constrictive pericarditis, restrictive cardiomyopathy, or right-sided heart failure, the right ventricle cannot accommodate the increased venous return. This leads to a rise in JVP instead.
➲ Homan sign ➔ calf pain on dorsiflexion of the foot, associated with deep vein thrombosis.
➲ Murphy sign ➔ inspiratory arrest due to pain on palpation of the right upper quadrant, seen in acute cholecystitis.
➲ Trousseau sign ➔ carpopedal spasm induced by inflating a blood pressure cuff, seen in hypocalcemia.
🔑 Clinical Pearl
Kussmaul sign is a bedside clue to impaired right ventricular filling. It helps differentiate constrictive pericarditis (positive Kussmaul sign) from cardiac tamponade (usually absent Kussmaul sign).

| 20 |  🧠 Empty Delta Sign — A Classic Clue to Cerebral Venous Sinus Thrombosis
A patient presents with severe headache, seizures, papilledema, or focal neurologic deficits. Contrast imaging reveals the classic “empty delta sign” — a triangular filling defect within the dural venous sinus.
👉 This is a hallmark of Cerebral Venous Sinus Thrombosis (CVST), most commonly involving the superior sagittal sinus.
⚠ Early recognition is critical because delayed diagnosis can lead to venous infarction, hemorrhage, and raised intracranial pressure.
