Severe haemoptysis associated with seizures in a dog.

ABSTRACT

CASE HISTORY A 7-year-old, sterilised male German Shepherd dog was presented with a history of three episodes of severe haemoptysis and associated dyspnoea within a 3-week period. A generalised tonic-clonic seizure was witnessed preceding the third episode. CLINICAL FINDINGS: Thoracic radiographs revealed a severe bilateral alveolar lung pattern of the caudodorsal lung fields; extension into the left cranial lung lobe was present but pulmonary vessels were within normal size limits. Frank blood was the only abnormality present at bronchoscopy. A coagulation profile, parasitological screening, thoracic and brain computed tomography (CT), and cerebrospinal fluid (CSF) cytological analysis did not identify any abnormalities. DIAGNOSIS Haemoptysis due to either severe neurogenic pulmonary oedema or rupture of the pulmonary capillaries secondary to seizures was considered a possible diagnosis. The primary generalised seizures were attributed to late-onset idiopathic epilepsy diagnosed by exclusion of other causes. CLINICAL RELEVANCE This is the first known case report describing severe haemoptysis associated with seizures in a dog.
