Last 5 Years PYQs in Radiology for NEET PG

Q1. What is the term used to describe the visual representation of the common femoral vein, common femoral artery, and the great saphenous vein at the saphenofemoral junction in an ultrasound examination?

1. Mickey mouse sign
2. String sign
3. Tillaux sign
4. Stamers sign

Ans. 1) Mickey mouse sign

• The appearance of the ultrasound (USG) at the saphenofemoral junction, showing the common femoral vein, common femoral artery, and the great saphenous vein, is referred to as the Mickey Mouse sign.
• In the Mickey Mouse sign, the common femoral vein represents the face of Mickey Mouse, and the common femoral artery and great saphenous vein represent the ears. This visual resemblance to the iconic Disney character gives rise to the term "Mickey Mouse Sign."

Q2. Plethoric lung fields are seen in?

1. TAPVC
2. Tricuspid atresia
3. Ebstein anomaly
4. TOF

Ans. 1)  TAPVC

• Plethoric lung fields refer to an increased pulmonary vascular marking seen on a chest X-ray. It indicates engorgement and dilation of the pulmonary vasculature, typically due to increased blood volume in the pulmonary circulation. In TAPVC, the pulmonary veins that normally carry oxygenated blood from the lungs back to the left atrium have abnormal connections, causing the blood to return to the heart in an abnormal manner. So, plethoric lung fields are seen in TAPVC, where abnormal connections between the pulmonary veins and the heart result in increased pulmonary blood flow and engorgement of the pulmonary vasculature

Q3. Which of the following conditions is indicated by the CT image below in a patient presenting with neck stiffness and severe headache?

1. Meningitis
2. Subarachnoid hemorrhage
3. Intraparenchymal hemorrhage
4. Hemorrhagic stroke

Ans. 2) Subarachnoid hemorrhage

• The CT image showing blood in the basal cistern is highly suggestive of subarachnoid hemorrhage.
• Bleeding due to trauma or rupture of an aneurysm (such as a saccular or arteriovenous malformation). Rapid time course.
• Patients complain of “worst headache of my life.” Bloody or yellow (xanthochromic) lumbar puncture.
• Vasospasm can occur due to blood breakdown or rebleed 3–10 days after hemorrhage and further ischemic infarct; nimodipine is used to prevent/reduce vasospasm.
• There is an increased risk of developing communicating and/or obstructive hydrocephalus.

Q 4. In the CT image, determine which muscle is impacted in a 15-year-old patient who has a past medical history of spinal tuberculosis. The patient was admitted to the hospital due to a low-grade fever, a dull backache, and continuous flexion of the hip joint. The hip joint motion is both restricted and painful.​​

1. 1
2. 2
3. 3
4. 4

Ans. 2) 2

• The arrow marking as 2 is psoas muscles, and in the context of a 15-year-old patient with a history of spinal tuberculosis and presenting with low-grade fever, dull backache, and persistent flexion of the hip joint, the involvement of the psoas muscle is highly suggestive of a psoas abscess.
  • Muscle from anterior aspect crossing hip joint anteriorly—Iliopsoas muscle.
  • Pulling the femur anteriorly causes the hip flexion.Iliopsoas muscle (proximal muscle): chief muscle for hip flexion.
• The psoas muscle is a large muscle located in the lower back that plays a key role in hip flexion and stabilization of the spine.
• Psoas abscesses can occur as a complication of spinal tuberculosis, with the infection spreading from the vertebral column to the adjacent psoas muscle.

Q5. A 25-year-old patient presented with acute epigastric pain and elevated serum lipase. He was stabilized after three days. What is the most common pathology associated with the chest X-ray obtained?​​

1. Acute Respiratory Distress Syndrome (ARDS)
2. Acute pulmonary edema
3. Pulmonary thromboembolism
4. Miliary tuberculosis (TB)

Ans. 1) Acute Respiratory Distress Syndrome (ARDS):

• The patient’s presentation with acute epigastric pain and elevated serum lipase indicates acute pancreatitis. Acute pancreatitis can lead to systemic inflammation and various complications, including ARDS, a type of non-cardiogenic pulmonary edema. ARDS leads to increased permeability of the pulmonary capillaries, resulting in the leakage of fluid into the alveoli, which causes diffuse opacities on a chest X-ray.

Q6. Which visual field defect is likely to be caused by the lesion shown in the given radiograph?​​

1. Altitudinal defect
2. Bitemporal hemianopia
3. Inferior arcuate scotomas
4. Bjerrum scotoma

Ans. 2) Bitemporal hemianopia

• The radiograph in question shows a craniopharyngioma, which is a suprasellar mass located above the optic chiasma. It compresses the optic chiasma and causes bitemporal hemianopia.​​

Q7. Identify the given fracture?​​

1. Burst fracture
2. Compression fracture
3. Chance fracture
4. Impacted fracture

Ans. 3) Chance fracture

• The given radiograph shows a chance fracture. Chance fracture usually occurs at the thoracolumbar junction (T10-L2). It is a horizontal fracture that extends through the spinous process, pedicles, and vertebral body, affecting the posterior and middle columns of the spine.

Q8. What condition is indicated by the MRCP image below?​​

1. Choledochal cyst
2. Cholangiocarcinoma
3. Cholelithiasis
4. Choledocholithiasis

Ans. 1) Choledochal cyst

• The given MRCP image shows a fusiform dilatation of the common hepatic and common bile ducts, which is suggestive of a choledochal cyst.

Q9. A patient presents with foul-smelling sputum, breathlessness, and fever. Based on the X-ray below, what is the most likely diagnosis?​​

1. Lung abscess
2. Pneumothorax
3. Pleural effusion
4. Pericardial effusion

Ans. 1) Lung abscess

• The given image shows an abscess cavity with an airflow level. The clinical presentation and the x-ray findings suggest a lung abscess.

Q10. Identify the condition depicted in the radiograph below.​​

1. Pancreatic calcification
2. Mesenteric calcification
3. Horseshoe kidney
4. Jejunal fecolith

Ans. 1) Pancreatic calcification

• The radiograph shows small, scattered calcifications typically associated with chronic pancreatitis. These calcifications are due to long-term inflammation and damage to the pancreas, leading to the deposition of calcium within the pancreatic ducts.
