This case study highlights pulmonary rheumatoid nodules, a rare condition mimicking tuberculosis and fungal pneumonia. Early diagnosis and appropriate immunosuppressive therapy led to significant improvement in the patient's condition.
Area of Science:
- Rheumatology
- Pulmonology
- Pathology
Background:
- A 64-year-old female with a history of tuberculosis and rheumatoid arthritis presented with chronic chest pain.
- Initial investigations including CT scans and biopsies suggested infectious causes like tuberculosis and cryptococcal pneumonia.
Observation:
- The patient underwent anti-tuberculosis treatment and right lower lobe resection for hydropneumothorax, with pathology revealing granulomatous inflammation.
- Despite treatment, CT scans showed increasing pulmonary nodules and cavities, leading to a consideration of cryptococcal pneumonia.
Findings:
- A definitive diagnosis of pulmonary rheumatoid nodules was established through pathological consultation of the resected specimen.
- Treatment with prednisone and mycophenolate mofetil resulted in significant improvement of pulmonary nodules and cavities on follow-up CT scans.
Implications:
- Pulmonary rheumatoid nodules can present as a diagnostic challenge, mimicking infectious lung diseases.
- Prompt diagnosis and management with immunosuppressive therapy are crucial for improving outcomes in patients with pulmonary rheumatoid nodules.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
