“…Gas, it will be observed, is not in itself a diagnostic criterion of much significance; in some cases it is absent or masked by the associated oedema, in most it is manifest only when the disease is already well advanced (14,106,143,155,261,432). Moreover, gassy wounds can occur in the absence of any clostridial infection: from the explosive effect of modern missiles (685, 833); in industrial accidents, from compressed air (269); from the activities of other organisms, of which the commonest is probably E. coli (25,87,224,261,511,526,663); or from various chemical agents, e.g., certain magnesium compounds (150, 683, 894). It may be added that SAttler (914) has recently given an excellent account of the differential diagnosis of gas in the tissues.…”

“…The absence of Enterobacteriaceae in all cultures made a perforation even less likely. Although intralesional gas formation in actinomycosis has previously been reported in the literature, the cause of the pneumoperitoneum in our patient remains unclear [13,15–17]. Actinomyces species or concomitant bacteria may both produce gas in these rare forms of actinomycosis, but Sasaki et al reported that “intralesional” gas is specific to osteomyelitis caused by Actinomyces [15].…”

Patient: Female, 42Final Diagnosis: Spontaneous pelvic-abdominal peritonitis due to actinomycesSymptoms: Abdominal distension • abdominal pain • acute abdomen • fever • intermenstrual bleeding • nausea • sepsis • septic shockMedication: —Clinical Procedure: —Specialty: SurgeryObjective:Unusual clinical courseBackground:Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature.Case report:We report a case of spontaneous pelvic-abdominal peritonitis with presence of pneumoperitoneum and absence of preceding abscesses due to acute actinomycosis mimicking a perforation of the proximal jejunum in a 42-year-old female with an intra-uterine contraceptive device in place. Explorative laparotomy revealed 2 liters of odorless pus but no etiological explanation for the peritonitis. The intra-uterine contraceptive device was removed. Cultivation showed growth of Actinomyces turicensis. The patient was successfully treated with penicillin.Conclusions:In the case of primary bacterial peritonitis or lower abdominal pain without focus in a patient with an intrauterine device in situ, Actinomyces should be considered as a pathogen.

“…3 In the maxillofacial region, infection is frequently of odontogenic origin, the result of oromaxillofacial trauma, dental manipulation, or dental caries. [1][2][3][4][5][6][7][8][9][10] Intraoral and panoramic radiographs are often used to assess various diseases and conditions of the maxilla and mandible in the dental clinic, 3 but the imaging findings are often nonspecific, and differentiating actinomycosis from other inflammatory or infectious conditions or from neoplastic processes is difficult and often necessitates additional imaging.…”

“…2,4 A few reports have described imaging findings of actinomycosis in the head and neck, [2][3][4]6,8,11 but the CT and MR imaging characteristics of MA have not been fully described. The purpose of this study was to evaluate the characteristic CT and MR imaging findings of MA.…”

SUMMARY:Mandibular actinomycosis is an uncommon disease. We retrospectively reviewed 6 patients with pathologically proven mandibular actinomycosis who underwent both CT and MR imaging to evaluate the characteristic imaging findings. CT results showed an irregularly marginated lesion with increased bone marrow attenuation, osteolysis, and involvement of the skin in all patients. Periosteal reaction and intralesional gas were seen in 4 patients. MR imaging results revealed low signal on T1-weighted and high signal on T2-weighted images of the mandible, and moderate heterogeneous enhancement was seen in all patients who received intravenous contrast. Cervical lymphadenopathy was not observed. Involvement of the masseter, lateral pterygoid, and medial pterygoid muscles was seen in 4 patients, whereas parotid gland and submandibular gland as well as parapharyngeal space involvement were seen in 3 patients. Familiarity with the imaging findings of mandibular actinomycosis may help to diagnosis this entity. ABBREVIATION: MA ϭ mandibular actinomycosis
