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.
足菌肿是一种由某些真菌引起的罕见深部真菌病。临床表现包括受累区域肿大及肿胀，伴有从病变处排出的颗粒。足部是最常受累的部位。对4例足部患有足菌肿的患者进行了研究。镓扫描在受累区域总是异常的，4例患者中有3例骨扫描异常。骨扫描正常的患者已接受有效治疗（7年）。其他患者的治疗效果不佳。尽管进行了长期治疗，但闪烁扫描结果似乎与急性骨髓炎合并蜂窝织炎病例中观察到的结果相似。骨和镓检查可能对足菌肿病例的治疗随访有一定价值。
