"Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a ...
The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, [4] especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. [4]
Solitary calcified nodules or granuloma - Discrete calcified nodule or granuloma, or calcified lymph node. The calcified nodule can be within the lung, hila, or mediastinum. The borders must be sharp, distinct, and well defined.
The exact mechanism of tuberculoma development has not been determined, although multiple theories have been proposed. It is possible that, following an initial tuberculosis infection resulting in bacteremia, a foci of granulomatous inflammation may coalesce into a caseous tuberculoma. [20]
Parenchymal Abnormalities: Close-up right upper zone 2/2 R/R; Small Opacities: The reader will categorize small opacities according to shape and size. The small, rounded opacities are p (up to about 1.5 mm), q (about 1.5 mm to about 3 mm), or r (exceeding about 3mm and up to about 10 mm).
What does “white lung” mean? Despite references to “white lung” and “white lung syndrome” floating around right now, it’s not a medical term, says Daniel Ganjian, M.D., a board ...
The left apical region is opacified in a case of granulomatosis with polyangiitis. Nasal or oral inflammation: painful or painless oral ulcers or; purulent or bloody nasal discharge; Lungs: abnormal chest X-ray with: nodules, infiltrates or; cavities; Kidneys: urinary sediment with: microscopic hematuria or; red cell casts; Biopsy ...
Aspergilloma in an old tuberculosis cavity; healed, calcified tuberculous lesions are also present towards the right of the image Healed tuberculous cavity, where the entire left lung is destroyed. Post-tuberculosis lung disease (PTLD) is ongoing lung disease that is caused by tuberculosis (TB) but persists after the infection is cured. [1]
