ABSTRACT
Pelvic actinomycosis is a rare entity that occurs almost exclusively in women, the presentation of which is usually non-specific and variable. Pelvic actinomycosis is almost always associated with the use of an intrauterine contraceptive device (IUD). Pelvic actinomycosis unrelated to IUD use is almost always associated with previous surgical procedures. The symptoms, clinical signs and radiological findings are usually non-specific, mimicking an ovarian malignancy. So an awareness of this rare condition and a proper diagnosis can avoid unnecessary surgeries because these cases can be treated with a prolonged course of antibiotics. We present a case of pelvic actinomycosis which masqueraded as an ovarian malignancy.

18F-FDG PET/CT imaging is an established imaging modality for cancer staging and response assessment. Its role in identifying infective and inflammatory pathologies from malignancy is debated. Dual time - point imaging is a refined technique used to overcome this interpretational dilemma. We present a 59 year old male with an unknown primary malignancy who was referred for a 18F-FDG PET/CT imaging. Images revealed primary lung malignancy with co existing bilateral renal tuberculosis which otherwise would have gone amiss or would have been considered as metastases.

We report here a case of a random synchronous male breast malignancy in a patient with a known base of tongue malignancy that was incidentally detected on a whole body 18-fluorine deoxyglucose positron emission tomography and computed tomography (18F-FDG PET/CT). Patient was referred to us for PET/CT staging and radiotherapy planning for a poorly differentiated squamous cell carcinoma of base of tongue. Histopathologically, the incidentally detected breast lesion was proven to be an invasive ductal carcinoma. 18F-FDG PET/CT being a whole body imaging modality is known to detect a considerable number of synchronous primaries. Synchronous malignancies in the head and neck area and the upper aerodigestive tract are well established. However, synchronous malignancy in male breast is reportedly uncommon. Our case is unique for the fact that a random synchronous dual malignancy of base of tongue and breast in a male patient was detected during a whole body 18F-FDG PET/CT imaging.
