FCPS Part 1 Radiology: Neuroradiology & Chest MCQs — High-Yield Concepts

Neuroradiology and Chest Radiology together make up 476 questions in HighYield's FCPS Part 1 Radiology bank (309 and 167 questions respectively) — two of the largest subspecialty blocks in the pool, and neither has had a dedicated practice post until now. Below is a sample set of Neuroradiology and Chest Radiology MCQs in the same one-line format the real exam uses.

Neuroradiology

1. On non-contrast CT, an acute epidural hematoma classically appears as a:

• A) Crescent-shaped collection that crosses suture lines
• B) Biconvex (lentiform) collection that does not cross suture lines ✅
• C) Diffuse effacement of sulci without a discrete collection
• D) Crescent-shaped collection that crosses the midline

2. A subdural hematoma differs from an epidural hematoma in that it:

• A) Is typically biconvex in shape
• B) Is usually arterial in origin
• C) Crescent-shaped and can cross suture lines ✅
• D) Never crosses the midline

3. The "owl's eyes" sign on axial T2 MRI of the spinal cord, reflecting anterior horn cell degeneration, is classically described in:

• A) Multiple sclerosis
• B) Amyotrophic lateral sclerosis ✅
• C) Transverse myelitis
• D) Syringomyelia

4. In an HIV-positive patient, a ring-enhancing brain lesion on contrast CT most commonly represents:

• A) Toxoplasmosis ✅
• B) Meningioma
• C) Pituitary adenoma
• D) Arachnoid cyst

5. The "hot cross bun" sign on axial T2 MRI of the pons is classically associated with:

• A) Progressive supranuclear palsy
• B) Multiple system atrophy ✅
• C) Parkinson's disease
• D) Wilson's disease

Chest Radiology

6. Visible air-filled bronchi outlined against opacified, fluid-filled alveoli on a chest X-ray is called the:

• A) Silhouette sign
• B) Air bronchogram sign ✅
• C) Deep sulcus sign
• D) Westermark sign

7. Loss of the normal right heart border outline on a frontal chest X-ray, due to adjacent consolidation, is known as a positive:

• A) Silhouette sign ✅
• B) Air bronchogram sign
• C) Kerley B line
• D) Cervicothoracic sign

8. Short horizontal lines at the lung periphery near the costophrenic angles, representing thickened interlobular septa in pulmonary edema, are called:

• A) Kerley A lines
• B) Kerley B lines ✅
• C) Fleischner lines
• D) Curly lines

9. A reverse-S-shaped fissure on chest X-ray, formed by a central hilar mass causing upper lobe collapse, is known as the:

• A) Golden S sign ✅
• B) Comet tail sign
• C) Luftsichel sign
• D) Deep sulcus sign

10. A widened mediastinum on a supine chest X-ray after blunt chest trauma should raise immediate suspicion for:

• A) Pneumothorax
• B) Traumatic aortic injury ✅
• C) Pericardial effusion
• D) Pulmonary contusion

Why These Deserve Dedicated Revision

Neuroradiology and Chest Radiology together account for a large share of the FCPS Part 1 Radiology paper, and much of the testing comes down to a finite list of classic signs — epidural vs. subdural, the silhouette sign, Kerley B lines, the Golden S sign — that either you recognise instantly or you don't. Drilling these in isolation, before mixing them with the rest of the radiology question pool, is one of the highest-yield uses of limited prep time.

HighYield's FCPS Part 1 Radiology QBank covers Neuroradiology and Chest Radiology alongside every other radiology subspecialty and the basic-sciences core, with every question explained.
