A five-year-old dog was referred with a five-month history of lethargy, decreased appetite, cough and intermittent forelimb lameness. Radiographs revealed an intra-thoracic lesion and a marked periosteal bone apposition of the second digit on the left forelimb. As it was palisading and circumferential, the latter appeared typical of hypertrophic osteopathy (HO). A grass awn in a sub-lobar ramification of the right caudal bronchus was identified and removed by bronchoscopy. At three months follow-up, the digit appeared clinically normal. On radiographs the periosteal bone reaction had decreased, indicative of resolving hypertrophic osteopathy. Thoracic radiographs showed no abnormalities five months after foreign body removal and the bone lesion on the digit had disappeared. Successful treatment of the pulmonary foreign body abscess led to spontaneous regression of HO and eventually to complete resolution of clinical signs. To the authors’ knowledge, this is the first reported case of HO secondary to a bronchial-pulmonary grass an abscess.
