[Multifocal bone tuberculosis: apropos of a case].
BACKGROUND
Tuberculosis of bone is rare (10 to 20 per cent of all skeletal tuberculosis). The multifocal form is exceptional even in endemic countries of tuberculosis. It constitutes less than 5 per cent of all osseous tuberculosis.


METHODS
O.H. 34 year-old, Moroccan woman of black race not vaccinated against tuberculosis, with a contagion, complained for a year from scapular pain and weight loss. She noticed that two masses had appeared six months ago. The patient was feverish (38 degrees). The physical exam showed a non inflammatory mass 10 cm wide located in front of the left sacroiliac joint and seeming to be a cold abscess. The radiologic assessment showed a lytic image of the humerus upper extremity, the right iliopubis branch, the left ischium and the left iliac wing. The surgical biopsy of the humerus showed an evolutive caseo-follicular tuberculosis. The nuclear scan of bone found two other localizations in the fourth lumbar vertebra and the ninth left rib. We concluded to a multifocal bone tuberculosis with seven localizations: The upper extremity of both humerus Right pubis Left ischium Left iliac wing 4th lumbar vertebra 9th left rib. The treatment consisted in a specific antibiotic therapy for 6 months associated to the evacuation of the cold abscess.


CONCLUSIONS
Multifocal bone tuberculosis is more frequent in young adults of black race. The beginning of the disease is progressive and the fistulas are the main reason of consultation. The radiologic lesions are not specific and have a geodic shape rimmed with an osteocondensation. Multifocal bone tuberculosis in black african predominate in flat bones. Otherwise in the white race it is located in the long bones extremities. The diagnosis of certitude is based on histologic findings of the peripheric bone lesion. The specific antibiotic therapy leads to the recovery if given early. Short protocols (9 or 6 months) are recently more used with success.
