SUBFOVEAL CHOROIDAL TUBERCULOMA IN A HEALTHY YOUNG WOMAN CAUSED BY MYCOBACTERIUM BOVIS.

PURPOSE: To describe a case of a macular tuberculoma in a young and healthy woman after developing a tuberculous lymphadenitis caused by Mycobacterium bovis .

METHODS

Retrospective case report.

RESULTS

Tuberculous lymphadenitis caused by M. bovis was detected after biopsy and histological examination as well as polymerase chain reaction test testing of cervical lymph nodes in a 20-year-old patient. An interferon gamma was positive. Shortly starting antitubercular therapy, the patient developed visual deterioration caused by a single yellowish subretinal structure in the macula of the right eye. Optical coherence tomography showed a dome-shaped, hyperreflective, subfoveal choroidal lesion with subtle subretinal fluid. Antitubercular therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide was performed, and the deescalation therapy with isoniazid and rifampicin was extended to 7 months. Further examinations showed regression of choroidal tuberculoma to a scar.

CONCLUSION

This is the first reported case of choroidal tuberculoma after tuberculous lymphadenitis caused by M. bovis .
