Background: Intracranial actinomycosis is rare bacterial infection without any characteristic clinical or radiological diagnostic features. Usual presentation is like pyogenic brain abscess, osteomyelitis with or without pachymeningitis and rarely as a parenchymal mass lesion. High index of suspicion should be kept in a patient with immunosuppression or predisposing factors like dental procedure, sinusitis, cardiac septal defects, cranio-facial trauma, cranial surgery, lung or abdomino-pelvic infection.

Actinomycosis is a chronic, suppurative, inflammatory granulomatous disease caused by gram positive anaerobic filamentous bacteria of the genus Actinomyces, most frequently Actinomyces israelii. We report a case of a 42-year-old male presenting with abdominal pain, a 10kg weight loss and a fixed mass in the epigastrium. Tomography revealed dilatation of the intestinal loops and thickening of the colon walls; the coexistence of these two findings suggested a lymphoproliferative process. Read More

The name "Actinomyces suis" was applied to each actinomycete isolate from swine actinomycosis by Grässer in 1962 and Franke in 1973. Nevertheless, this specific species was not included in the "Approved List of Bacterial Name" due to absence of the type cultures. Therefore, "Actinomyces suis" based on the description of Franke 1973 has been considered as "species incertae sedis". Read More

Actinomyces israelii, a commensal of the bronchial and gastrointestinal tracts, is responsible for the majority of actinomycostic infections in humans. Actinomycosis has widely varying clinical presentations ranging from asymptomatic states to infiltrative mass lesions that mimic malignant abdominopelvic disease. Described as one of the most misdiagnosed diseases, actinomycosis poses challenges to accurate preoperative diagnosis. Read More

This article describes a case of large persistent posttreatment apical periodontitis associated with 2 maxillary incisors, which was successfully managed by periradicular surgery. Histobacteriologic analysis revealed that the lesion was a granuloma that contained in its body a very large actinomycoticlike colony surrounded by accumulations of polymorphonuclear leukocytes and showing no direct communication with the root canal systems from both teeth. One incisor had no evidence of persistent intraradicular infection, whereas the other exhibited some residual dentinal tubule infection in the apical canal, which may have not significantly contributed to persistent inflammation given the organization and agglomeration of inflammatory cells around the large extraradicular bacterial colony.
