Summary

We report the case of a 30-year-old housewife who presented with fever and lower abdominal pain, and was diagnosed with an adnexal collection. Initial evaluation was suggestive of tubercular pelvic inflammatory disease (PID). Subsequently, from a culture of pus aspirated from the collection grew out Nocardia species. She was treated with amikacin and cotrimoxazole and made a complete recovery. Clinical and laboratory evaluation for immunosuppression was negative. Primary abdominal nocardiosis is an unusual cause for PID and an important differential diagnosis for tuberculosis.
