The chest radiograph in leptospirosis in Jamaica

RE Lee, SI Terry, TM Walker and AE Urquhart

A consecutive series of 44 patients with proven leptospirosis was studied to document the radiographic pulmonary abnormalities, assess their prevalence, correlate them with the clinical signs and symptoms and determine their prognostic significance. Abnormalities were found in ten patients (23%), this prevalence being less than previously noted. The abnormalities shown were non-segmental opacification (consolidation-eight cases), basal linear opacities (collapse-five cases) and pleural effusions (four cases). The first radiographic demonstration of a large pleural effusion in leptospirosis is recorded. Non-jaundiced patients had a higher prevalence (43%) of these abnormalities than jaundiced (13%). No other correlation with clinical signs or symptoms was found. The presence of these abnormalities had no prognostic significance. It is concluded that the presence of radiographic pulmonary abnormality in in-patients with leptospirosis is common. These abnormalities are non-specific and can mimic other diseases leading to diagnostic difficulty. Such abnormalities may be extensive in the absence of clinical signs and symptoms.
