Scintigraphic evaluation of mycetoma.
Mycetoma is a rare deep mycosis caused by certain fungi. Clinical findings include enlargement and tumefaction of the affected region accompanied by grains coming out of the lesions. The feet are the most frequently affected area. Four patients have been studied who presented with mycetoma of the feet. Gallium scintigraphy was always abnormal in the affected areas and bone scintigraphy was abnormal in three of the four patients. The patient who had a normal bone study had received effective treatment (7 years). In the other patients the results were poor. Scintigraphic findings seem to be similar to those noted in cases of acute osteomyelitis associated with cellulitis, despite long-term therapy. Bone and gallium studies may be of possible value for therapy follow-up in cases of mycetoma.
