Pulmonary aspergillosis (cow 2). Section of lung from a 2 year old cow with weight loss and anorexia since calving. On necropsy examination, multiple firm masses were identified throughout the lungs. These were cavitating in nature, with a necrotic centre and peripheral fibrosis. Both this section and the following one are taken from the edge of such a lesion and demonstrate the pyogranulomatous inflammatory response.

Embolisation 7 – patient WC. Angiogram of the lateral thoracic artery on subtraction film showing grossly abnormal vasculature inferiorly shunting along several anterior intercostal arteries to the internal mammary artery. In addition a pseudoaneurysm is shown.

Embolisation 6 – patient WC. Catheter tip in the lateral thoracic artery on screening film.
-
Grocott (silver) stain showing branching septate hyphae fairly typical of Aspergillus in mucus. The apparent right angle branching is unusual.
-
Bronchial mucosa under H & E stain showing numerous eosinophils deep to the mucosa, and mucus in the lumen of the bronchiole.

Severe kyphoscoliosis caused by greater than 40 years of prednisolone for ABPA and asthma.

These pictures show remarkable curvature of the spine as a result of collapse of the vertebral bodies of the thoracic vertebrae. This is a gross example of steroid-induced osteoporosis. The dose was not large in the last 10 years, typically 5-10mg daily, but multiple high dose courses and slow tapering lead to this outcome.
Her corticosteroid warning card is also demonstrated, as additional steroids are required for any significant illness or surgery, as her adrenal glands had completely atrophied.
