3 years old male, not castrated British shorthair cat with history of tetraparesis was referred to the clinic for Computed Tomography. Mineral-attenuating endobronchial lesions were detected in Thorax as accidental finings in spinal CT. The finding is specific for broncholitiasis.
CT features: Multifocal mineral-attenuating endobronchial lesions in cranial and middle right and cranial left lung lobe are present. There is mild generalized thickening of the bronchial walls and consolidation of right middle lung lob with regional bronchiectasis
X-ray features: Multiple mineral opacity nodules with irregular margins are present within left and right cranial and right middle lung lobe. The largest of which lies within the right middle lung lobe and interstitial patter in this region is present.
Broncholithiasis is very rare condition in cats and is defined as the presence of calcified or ossified material within the bronchial lumen. Only four cases of broncholithiasis in cats have been reported in the veterinary literature. Normal this condition is associated with lower airway inflammation, but in this case the owner does not report for respiratory problems. Broncholithiasis is an uncommon condition, which should be considered as a differential diagnosis for cats with chronic respiratory disease. Affected cats may develop broncholithiasis secondary to a diffuse inflammatory lower airway disease with mineralisation of secretions in the airways.
