Objective: To establish the diagnosis of mycetoma in the foot by imaging and identify the principal radiological signs. Materials and methods: Six patients with foot mycetoma were evaluated with plain x-ray, ultrasound, and magnetic resonance (MR) after confirming the diagnosis by histopathology and culture Mycetoma pedis or Madura foot is the name used to indicate a clinical entity resulting from invasion of the foot, and occasionally other parts of the body, by a filamentous fungus. It is thought that the fungus is usually introduced by the prick of an infected thorn or splinter
Maduromycosis, also known as maduramycosis or eumycetoma, is caused by various fungi (e.g. Madurella mycetomi) or actinomycetes (e.g. Nocardia brasiliensis) which usually affect the feet Plain radiographic classification of the pattern, extent and severity of bone involvement in mycetoma of the foot can be used in planning and monitoring treatment response.2In this classification, stage 0 indicates the presence of only soft tissue swelling without bone involvement Plain radiographs showed translucence at interphalangeal joint and moderate sclerosis of the second finger of the left foot. X-ray imaging shows classically a so-called snow-melt form. Ultrasound images of the left foot showed a mainly hypointense lesion containing small, discrete, hyperechoic foci Teaching Points by Dr MGK Murthy, Dr GA Prasad 1. Mycetoma or Madura foot is a chronic granulomatous infection of the dermis and epidermis caused by the bacteria Actinomyces (Actinomycetoma) or by true fungi (eumycetoma) A clinical image (Fig. 1) of the lateral aspect of the right foot elicits painful swelling with multiple discharging nodules. The largest nodule appears black. X-ray right ankle AP (Fig. 2a) and oblique (Fig. 2b) views show soft tissue swelling over lateral aspect and sclerosis of calcaneum with multiple patchy lucent areas, resembling a moth.
Introduction. Mycetoma is a recognised neglected tropical disease that for a long time has been accorded inadequate attention across the globe. 1, 2 It is a chronic destructive inflammatory disease caused by fungi (eumycetoma) or actinomycetes (actinomycetoma). 3, 4 It is endemic in tropical and subtropical regions, with the highest incidence in Sudan. 5, 6 It affects the poor in disadvantaged. Mycetoma means a fungal tumor. Mycetoma is a chronic, granulomatous, subcutaneous tissue infection caused by both bacteria (actinomycetoma) and fungi (eumycetoma). This chronic infection was termed Madura foot and eventually mycetoma, owing to its etiology Mycetoma is a disease caused by certain types of bacteria and fungi found in soil and water. These bacteria and fungi may enter the body through a break in the skin, often on a person's foot. The resulting infection causes firm, usually painless but debilitating masses under the skin that can eventually affect the underlying bone
Diagnosis : Over 30 species have been identified as causes of mycetoma. The grains of many of these species have overlapping morphological features. Culture is required for accurate identification of the agent. Diagnosis may also involve radiology, ultrasonic imaging, cytology, histology or immunodiagnosis Abstract Mycetoma is a chronic granulomatous disease that is more common in tropical regions with predominant involvement of foot. Spinal mycetoma presenting as lumbar canal stenosis is extremely rare
Mycetoma is a chronic disease usually of the foot but any part of the body can be affected. Infection is most probably acquired by traumatic inoculation of certain fungi or bacteria into the subcutaneous tissue. The disease commonly affects young adults, mostly males aged between 15 and 30 years in developing countries In the absence of typical clinical features of discharging sinuses, mycetoma foot may clinically mimic a neoplasm or a chronic bacterial or tuberculous infection . MRI findings that are specific to the diagnosis of this condition would aid in the early diagnosis of this chronic infection and differentiate it from such conditions Anteroposterior radiograph of a patient's right arm, revealing the bony involvement of the distal humerus in a case of actinomycetoma caused by Nocardia species Massive eumycetoma of the right foot in a 40 year-old male patient from central Sudan caused by Madurella mycetomatis.

Madura's foot, or mycetoma of the foot, is a slow growing infection, characterized by a thick and swollen lesion with sinuses draining a seropurulent and serosanguinous exudations containing granules with different colour (yellow, white, black, brown, or red) according to the type of eumycetes (4, 5 The term Madura foot was first introduced by Colebrook, 1-in 1846, to describe a growth most frequently noted on the feet of natives in Madura, India. The condition, however, had been known for many years and probably had been confused with elephantiasis. In 1860, Vandyke Carter 1 first designated the condition as mycetoma Three patients referred for MRI of the foot were found to have imaging features characteristic of mycetoma.

X-ray. Radiologic changes in bones are late sequelae of the disease. The basic radiologic changes of osseous structures include osteoporosis, loss of cortical margin, erosion, lytic lesions and bony expansion. The tarsometatarsal region is commonly affected in mycetoma This study aimed to present the 'dot-in-circle' sign, which indicates the typical magnetic resonance imaging (MRI) and ultrasonographic (USG) findings for mycetoma involving soft tissue and bone. A total of 8 cases with histopathological proof of mycetoma affecting the musculoskeletal system, and that were examined via MRI and/or coexistent diagnostic ultrasonography between 2004 and 2013. Imaging performed were X ray foot and MRI. Osteomyelitis was noted in 4 patients (50%). Medical therapy plays a major role in the treatment of mycetoma foot even if the bone is involved. Mycetoma can be identified by directly examining discharged 'grains' of fungal spores under a microscope, but further tests are needed to confirm the diagnosis. There are no simple diagnostic tests to use in villages, requiring patients to travel to referral hospitals for diagnosis, which may include biopsy and x-ray or ultrasound The mycetoma mass invades the left parapharyngeal space and almost reaches the lumen of the pharynx.

Mycetoma is diagnosed through microscopic examination of the grains in the nodule and by analysis of cultures. Since the bacterial form and the fungal form of mycetoma infection of the foot share similar clinical and radiological features, diagnosis can be a challenge. Magnetic resonance imaging is a very valuable diagnostic tool. However, its.

Madura foot or mycetoma is a chronic granulomatous disease of the subcutaneous tissue, that can progress to deeper structures like muscles or bones [1-3]. It is caused either by fungi (eumycetoma) or by aerobic fila-mentous bacteria (actinomycetoma) [1, 4]. It affects mostly lower extremities of the body, especially foot Mycetoma eumycetoma and actinomycetoma Mycetomas (Madura foot) are endemic in the tropics and sub-tropics. They are chronic, granulomatous, subcutaneous infections caused by either actinomycetes bacteria or eumycetes fungi, giving rising to actinomycetomas and eumycetomas, respectively. Radiology and ultrasound enable assessment of.
Mycetoma can be caused by bacteria (actinomycetoma) or fungi (eumycetoma) and typically aff ects poor communities in remote areas. It is an infection of subcutaneous tissues resulting in mass and sinus formation and a discharge that contains grains. The lesion is usually on the foot but all parts of the body can be aff ected Mycetoma was described in the modern literature in 1694 but was first reported in the mid-19th century in the Indian town of Madura, and hence was initially called Madura foot. 3. Mycetoma commonly affects young adults, particularly males aged between 20 and 40 years, mostly in developing countries. 4 Keyword: Madura Foot, Mycetoma, Biopsy lesion, Actinomycosis, eumycetoma I. INTRODUCTION Mycetoma was first documented in the mid-nineteenth century and was dubbed Madura foot after Madurai, Tamil Nadu, India, where the illness was discovered (1). Madura foot, also known as mycetoma, is a chronic and progressive subcutaneou Extension occurs due to nodule swelling and coalescence, resulting in large tumors that can evolve into necrotic abscesses with sinus tracts. May progress over months to many years. Can extend from skin and subcutaneous tissue to muscle, bone, and lymphatic vessels. Pain is usually associated with secondary bacterial infection
