Understanding Right Apical Lung Densities: Radiology Interpretation

The phrase "suspicious right apical densities suggest alveolar" is a radiology impression indicating concerning opacities in the right lung apex with alveolar pattern.

Breakdown

• Right Apical: Right upper lobe apex (superior segment).
• Densities: Increased opacity (whiter on X-ray) = fluid, cells, fibrosis, or mass replacing air.
• Suggest Alveolar: Alveolar pattern = airspace filling (consolidation, ground-glass) vs. interstitial (lines/reticulation). Alveolar suggests pneumonia, edema, hemorrhage, adenocarcinoma.

Differential Diagnosis

• Infection: TB (classic apical), bacterial pneumonia, fungal.
• Malignancy: Primary lung cancer (Pancoast if superior sulcus), metastasis.
• Inflammatory: Sarcoidosis, organizing pneumonia, vasculitis.
• Chronic: Fibrosis (post-TB, radiation), scarring.
• Congenital/Vascular: AVM, sequestration.

Additional Findings

• "Heart size normal": Cardiothoracic ratio <0.5 — no cardiomegaly.
• "Sulci intact": Brain cortical sulci visible (incidental on chest CT) — no effacement, mass effect, or hydrocephalus.

Next Steps

1. Chest CT (thin-section) for characterization.
2. Compare prior imaging.
3. Clinical correlation: symptoms, risk factors, labs.
4. Biopsy if suspicious for malignancy.

Apical densities require systematic evaluation — TB and cancer are "must not miss."
