1,2) We describe the case of a patient with an extremely rare form of generalized enchondromatosis who presented with an enchondroma of the clivus.
Her surgical history was significant for excision of a right nasal cavity enchondroma for nasal obstruction, spine fusion, debulking of an extensive left shoulder enchondroma, and multiple foot surgeries.
Here we present an interesting case of Maffucci syndrome with a history of malignant transformation of enchondromas and recurrent hemangiomas that required multiple prophylactic surgical excisions.
A 58-year-old male with multiple enchondromas experienced malignant degeneration of one into a chondrosarcoma of the distal femur.
In fact, radiographs of the hands and feet are often pathognomonic in Maffucci syndrome, showing multiple soft tissue masses containing phleboliths in addition to the multiple enchondromas (14).
Additionally, MRI visualized one hydrocele, one osteoma of the left femur, an enchondroma of the left superior ramus of the pubic bone, and one dilated left ureter.
The other findings like hydrocele, enchondroma, osteoma, ischiadic tubercle edema and dilation of the ureter may be interpreted to underline the value of MRI for detection of unexpected pathology of the soft tissues and even the bones in the groin and pelvic area that may account for one aspect of the groin pain (Leander, 2000).
Conclusions: In the setting of pain with no other abnormal findings, MRI can differentiate between bone infarct and enchondromas usually, but chondrosarcoma versus enchondroma must be differentiated with biopsy.
Enchondroma versus chondrosarcoma in the appendicular skeleton: Differentiating features.
This is seen in lesions such as enchondroma and chondrosarcomas.
Magnetic resonance (MR) imaging demonstrates the enchondromas to be well-delineated, lobulated masses that have low signal intensity on T1-weighted images and high signal intensity on T2-weighted images (Figure 4).
Ollier's disease also confers an increased risk of malignancy, with transformation of the enchondromas into chondrosarcomas being noted, most often around age 40.
