Mastoiditis and Tegmen Tympani Defect Leading to Intracranial Abscess with Actinomyces odontolyticus

Actinomyces odontolyticus bacteremia.

We describe two immunosuppressed female patients with fever and Actinomyces odontolyticus bacteremia, a combination documented once previously in an immunocompetent male patient. The patients were treated with doxycycline and clindamycin; these drugs, with beta-lactams, are effective treatment for A. odontolyticus infections.

Actinomyces Odontolyticus - Associated Bacteremia

Many Actinomyces species are part of the oral microflora of humans. Actinomyces odontolyticus associated infections are exceptionally rare, presenting an endogenous infection originating from mucous membranes. Immunodeficiency is often complicated by severe opportunistic bacterial infections leading to critical condition of the patient. We report a case of an immunosuppressed patient with fever...

Malar mass due to Actinomyces odontolyticus.

Actinomyces odontolyticus was isolated from a patient with a soft tissue mass in the malar region. The organism was identified on the basis of morphological, cultural, and biochemical characteristics. On histological examination, the tissue mass contained several granulomatous foci with small, basophilic staining areas resembling microscopic sulfur granules. This is believed to be the first rep...

Tegmen Tympani Defect and Brain Herniation Secondary to Mastoid Surgery: Case Presentation

Brain herniation into the middle ear is very rarely seen. In addition to reasons like congenital factors, trauma, and infection, tegmen defect may develop as a result of iatrogenic events secondary to chronic otitis media surgery with or without cholesteatoma. Since it may cause life-threatening complications, patients must be evaluated and monitored for tegmen defect. In this paper, diagnosis ...
