Mycetoma of the foot, commonly referred to as Madura foot, is a chronic granulomatous infection, which impacts vascularization of the affected region. This study aimed to evaluate foot mycetoma using Doppler and sonography techniques to identify the principle sonographic features and blood flow patterns associated with the condition.
This was a cross-sectional prospective single-center study conducted at the Mycetoma Research Center (MCR) in Khartoum State, Sudan. Sixty patients with Madura foot were examined using a Duplex ultrasound machine with a 7-10 MHZ linear probe. Data was analyzed using SPSS software. The distribution of demographic data was evaluated by simple descriptive statistics. Statistical tests was performed using Student's independent t-tests to compare different forms of mycetoma and Chi-square tests to examine differences in blood flow patterns between fungal (eumycetoma) and bacterial (actinomycetoma) forms of the infection.
The presence of multiple cavities and aggregated grains were more common in eumycetoma than in actinomycetoma. The echotexture was significantly more heterogeneous in eumycetoma than in actinomycetoma (p = 0.03). Eumycetoma had higher vascularity than actinomycetoma.
Mycetoma has characteristic sonographic features and patterns of vascularity, which are essential to differentiate between the fungal and bacterial forms of mycetoma.
足部真菌病，通常称为 Madura 足，是一种慢性肉芽肿性感染，会影响受影响区域的血管化。本研究旨在使用多普勒和超声技术评估足部真菌病，以确定与该疾病相关的主要超声特征和血流模式。
这是一项在苏丹喀土穆州 Mycetoma 研究中心（MCR）进行的横断面前瞻性单中心研究。使用带有 7-10 MHZ 线性探头的 Duplex 超声仪对 60 名 Madura 足患者进行检查。使用 SPSS 软件分析数据。使用简单描述性统计数据评估人口统计学数据的分布。使用 Student's independent t-tests 进行统计检验，以比较不同形式的真菌病，使用 Chi-square 检验来检查感染的真菌（外生菌）和细菌（放线菌）形式之间的血流模式差异。
在真菌病中，多个腔和聚集的颗粒比在放线菌病中更为常见。真菌病的回声纹理比放线菌病明显更为异质（p = 0.03）。真菌病的血管化程度高于放线菌病。
真菌病具有特征性的超声特征和血管化模式，对于区分真菌和细菌形式的真菌病至关重要。
