A 25 year old male known case of Sturge Weber syndrome with HBS positive status presented to you with complaints of high grade fever with chills and rigor followed by pleuritic chest pain. He staed to have cough, breathlessness and yellow sputum. Chest X – ray showed nonhomogenous opacity in the right lower zone with air bronchogram. What would be the diagnosis in this setting:

**Core Concept**
Sturge Weber syndrome is a neurocutaneous disorder characterized by a port-wine stain on the face, seizures, and glaucoma. The patient's immune status, indicated by a positive HBs status, makes him susceptible to infections, including those caused by the hepatitis B virus. The patient's presentation with high-grade fever, pleuritic chest pain, cough, breathlessness, and yellow sputum suggests a severe respiratory infection.

**Why the Correct Answer is Right**
The patient's symptoms and chest X-ray findings are consistent with a diagnosis of pulmonary tuberculosis (TB). The nonhomogenous opacity in the right lower zone with an air bronchogram is a classic radiographic finding of TB. The patient's compromised immune status, likely due to his HBs status, increases his susceptibility to TB. The Sturge Weber syndrome itself does not directly contribute to the patient's current respiratory symptoms, but it does indicate a potential underlying immunocompromised state.

**Why Each Wrong Option is Incorrect**
**Option A:** Pneumonia is a possible diagnosis, but the patient's immune status and the radiographic findings make TB a more likely diagnosis. Pneumonia typically presents with a more homogeneous opacity on chest X-ray.

**Option B:** Bronchiectasis is a possible complication of TB, but it is not the primary diagnosis in this case. Bronchiectasis would typically present with more chronic symptoms and findings on chest X-ray.

**Option C:** Pneumothorax is not suggested by the patient's symptoms or chest X-ray findings. The air bronchogram is a sign of alveolar consolidation, not air in the pleural space.

**Option D:** Aspiration pneumonia is a possibility, but the patient's symptoms and radiographic findings are more consistent with TB. Aspiration pneumonia typically presents with a more acute onset and findings of aspiration on chest X-ray.

**Clinical Pearl / High-Yield Fact**
In immunocompromised patients, TB can present atypically, making it essential to consider TB in the differential diagnosis even in the absence of classic symptoms. A high index of suspicion and prompt diagnostic testing are crucial in these cases.

**Correct Answer:** B.

✓ Correct Answer: A. Pneumonia
