Abstract:
We report a 64-years-old woman who underwent sparing mastectomy with adjuvant radiotherapy for breast cancer. One month after the end of radiotherapy, she presented with malaise, fever, fatigue, cough and migratory bilateral pulmonary infiltrates on serial radiological images. The microbiological studies of broncha alveolar lavage were negative. The patient under went a trans bronchial biopsy and the pathological diagnosis was compatible with an organizing pneumonia presumably associated with radiotherapy. Systemic steroid treatment was successful with rapid and complete resolution of clinical and radiographic manifestations.

Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
