“…6,8,12 CT scan is an objective imaging technique to follow-up the effectiveness of the treatment. Notwithstanding, the MRI shows a higher sensitivity for detecting residual disease compared with the CT. 16,17 In the present case, antibiotic treatment was enough to reach the cure. Although the prognosis of this infection is good with proper medical treatment, with or without surgery, actinomycosis still can lead to the death in cases of tough early diagnosis or/and severe infection.…”

Actinomycosis is an uncommon, endogenous, and chronic infection with varied and nonspecific clinical features such as abdominal, pelvic or cervical masses, ulcerative lesions, abscesses, draining fistula, fibrosis, and constitutional symptoms. The disease ensues when the bacteria disrupt the mucosal barrier, invade, and spread throughout interfascial planes. Currently, the diagnosis of actinomycosis is challenging because of its very low frequency and depending on the clinical presentation it may masquerade malignancies. Therapy consists initially in intravenous penicillin, followed by an oral regimen that may be extended until a year of treatment. A timely diagnosis is crucial to avoid extensive therapeutic attempt as surgery. However, a biopsy or drainage of abscesses and fistula's tract may be required not only as a diagnostic procedure as part of the therapy. We report the case of a 72-year-old woman with an abdominal mass initially misdiagnosed as a liposarcoma. A second biopsy of a skin lesion of the abdominal wall made the diagnosis of actinomycosis, avoiding a major surgical procedure. The patient was treated with a long-term course of antibiotics with favorable outcome. Liposarcoma was ruled out after the patient's full recovery with antibiotics and the misdiagnosis was credit to the overconfidence on the immunohistochemical positivity to MDM2.

“…[5][6][7][8][9] If there are many avascular spaces due to severe tissue reaction, medical therapy sometimes needs longer duration. 4,5,[8][9][10]12,16,17 In most cases, surgery can be avoided, or a minor procedure may be necessary to aid the therapy. Some patients may require the drainage of an abscesses or excision of a fistula.…”

A 51-year-old male with a clinical history of abdominal pain and bloody diarrhea underwent spiral computed tomography of the abdomen with intravenous contrast medium enhancement. The findings were an inflammatory mass with cystic and solid characteristics arising from the ileocecal region and extending to the peritoneum and right iliopsoas muscle, with adjacent lymphadenopathy. Histology after surgical resection confirmed the diagnosis of actinomycosis lesions in perienteric fat.
