A unique case report, probably first case from India, of lung abscess caused by Streptococcus intermedius in a previously untreated patient with Type 2 diabetes mellitus is reported here. The patient presented with non-productive cough and right-sided chest pain. Microbiological evaluation confirmed the presence of Streptococcus intermedius and the patient responded positively to antibiotic therapy. This case highlights the fact that S.intermedius may act as pathogen in immunocompromised individuals. So, a caution is needed by the medical fraternity before disregarding it as a commensal.

OBJECTIVE: Computed radiography (CR) has provided a ready cost-effective transition from screen film to digital radiography and a convenient entrance to PACS. This article revisits artifacts encountered in CR systems. These artifacts may obscure abnormalities, mimic a clinical entity, or hamper image quality. CONCLUSION: With the new-generation CR systems, software- and hardware-related artifacts have decreased, making operator errors more evident. The purpose of this study is to establish the current trend of CR artifacts and the new facets in identifying and resolving problems quickly that will help prevent future occurrences. This article also brings to light the importance of constant review required of this extensively studied topic to avoid diagnostic misadventures.
