**Core Concept**
Tuberculosis (TB) in HIV-infected patients often presents with atypical radiographic findings due to the compromised immune system. In these patients, TB can manifest with a wider range of radiographic patterns, including miliary TB, TB lymphadenitis, and pulmonary TB with cavitation.

**Why the Correct Answer is Right**
The correct answer is related to the fact that HIV-infected patients with TB are more likely to present with miliary TB, which is characterized by a diffuse, widespread pattern of small, rounded opacities on the chest X-ray, representing the dissemination of TB bacilli to the lung parenchyma. This is due to the impaired cellular immunity in HIV-infected patients, which allows the TB bacilli to spread more easily throughout the body.

**Why Each Wrong Option is Incorrect**
**Option A:** Miliary TB is a common finding in HIV-infected patients with TB, so this option is incorrect.
**Option B:** TB lymphadenitis, characterized by enlarged lymph nodes in the chest X-ray, is also a common finding in HIV-infected patients with TB, making this option incorrect.
**Option C:** Pulmonary TB with cavitation is also a possible finding in HIV-infected patients with TB, although it is less common than miliary TB, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
Miliary TB in HIV-infected patients can be challenging to diagnose, and a high index of suspicion is necessary based on clinical presentation and radiographic findings. A thorough investigation, including sputum smear microscopy, culture, and histopathology, is essential for confirming the diagnosis.

**Correct Answer: D.**
