Diagnostic challenges of an atypical presentation of ear and mastoiditis tuberculosis in a-5-year-old child in a developing country: A case report and review of literature

Abstract

We report a case of a 5-year-old girl who came to Otolaryngology Outpatient Clinic of our hospital with the chief complaint of recurrent ear discharge which had started to appear since 3 years ago and had recurred every month despite repeated antibiotics and antifungals ear drops treatments, given by general practitioners and otolaryngologists. Gram staining, acid-fast staining and Mycobacterium tuberculosis culture examination from the discharge had never been conducted. There was a history of inadequate weight increment since she was 2 years old. Her uncle who often met her died about 6 months ago due to TB disease. She was initially diagnosed with otitis media from the previous clinicians before finally referred to our hospital due to the perforated tympanic membrane. Otoscope examination showed perforated tympanic membrane. CT scan showed right osteomastoiditis with cholesteatoma with destruction of right mastoid antrum and right ear bone. We did not find pale-looking granulomatous tissue or multiple perforated tympanic membrane. The patient was diagnosed with chronic suppurative otitis media (CSOM) of the right ear with right mastoiditis and right posterior auricle fistulae. Afterwards, canal wall up, canaloplasty, mastoid obliteration, tympanoplasty, and rotational flap right ear were performed. Histopathology examination revealed the presence of caseous necrosis and datia langhans cells. Based on her chronic illness supported by the histopathological findings, anti-tuberculosis therapy was commenced. No more ear discharge complained and her body weight started to increase after oral anti tuberculosis treatment.
