 Admission chest radiography revealed a suspicious left lower lobe mass with multiple smaller pulmonary nodules in the lower zones (Fig. 1A). Contrasted chest CT was performed the following day, which showed an irregular left lower lobe mass (37 x 28 x 26 mm) with multiple posterior lower lobe subpleural nodules, sub-centimetre mediastinal and bilateral hilar nodes, no pleural effusions and background paraseptal emphysematous changes in the upper lobes (Fig. 1B).  Chest radiography revealed that the left lung mass had resolved at 8 weeks of follow-up (Fig. 1C), the RPR titre decreased to 1:64, and normalisation of serum calcium and liver function.
