Presentation
Patient with a history of recurrent pneumonia.
Patient Data
An endobronchial lesion with negative HU values (-60 HU) in the left lower lobe bronchus measuring 1.3 cm, consistent with macroscopic fat and almost completely filling the lumen.
Left lower lobe consolidation due to postobstructive pneumonia.
The pathology study revealed the lesion to be a benign mesenchymal neoplasm made up of mature adipose tissue surrounding bronchial glandular structures. In view of these findings a diagnosis of endobronchial lipoma was made.
Case Discussion
Endobronchial lipoma is a rare benign neoplasm of the tracheobronchial tree, that represent 0.1% - 0.5% of the lung neoplasms. They are common in men, with peak incidence between the fifth and six decandes of life. Obesity and smoking are considered risk factors, although there are no conclusive studies. In most cases described in the literature, the tumour is located in the first three subdivisions of the tracheobronchial tree, and is more common on the right side, although in our case, it originated in the left lower love bronchus.
Cough, progressive dyspnoea, heamoptysis and recurrent pneumonia are the most common forms of presentation.
