Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Lobar collapse occurs due to loss of volume in a lung lobe, usually from bronchial obstruction. Radiological clues include volume loss, fissure displacement, and shift of surrounding structures.
Step 1: Identify the radiological pattern.
The image-based diagnosis involves the right upper lobe.
Step 2: Differentiate collapse from consolidation.
Consolidation usually causes opacity without marked volume loss. Collapse shows volume loss and displacement of fissures or mediastinal structures.
Step 3: Select the diagnosis.
The image is most consistent with: \[ \text{Collapse of right upper lobe} \] Therefore, the correct answer is Collapse of right upper lobe.
