    Chondroid lipoma: MRI appearances with clinical and histologic correlation (1996)
    Springer

    Notes: Abstract  Chondroid lipoma is a recently described benign tumor of adipose origin which, pathologically, mimics myxoid liposarcoma and myxoid chondrosarcoma. This tumor typically presents as a well-defined mass in the superficial tissues of the extremities. In this report, we present the magnetic resonance imaging (MRI) appearances of a pathologically proven chondroid lipoma. To our knowledge, this is the first report of any imaging findings associated with this tumor.

    Candida osteomyelitis and disc space infection of the lumbar spine (1997)
    Springer

    Notes: Abstract  Candida osteomyelitis is an uncommon complication of immunosuppressive therapy. Its radiographic manifestations are similar to those of other relatively indolent infectious agents. We report the CT and MR findings in a patient who developed this condition following treatment for acute myelogenous leukemia, and review the imaging literature covering similar cases.

    Malignant degeneration of an osteochondroma with unusual intra-bursal invasion (1999)

    Notes: Abstract  Multiple hereditary osteochondromatosis is an uncommon autosomal dominant condition in which patients are predisposed to the development of chondrosarcoma. We report a case of a patient who developed a secondary low-grade chondrosarcoma in this setting. The tumor was associated with an unusual multinodular invasive growth pattern into a pre-existing bursa that was present overlying the osteochondroma.

    Magnetic resonance imaging of the temporomandibular joint: diagnostic difficulty caused by extensive pneumatization of the mastoid air cells (1999)
    Springer
    Skeletal radiology 28 (1999), S. 577-580 
    Details
    ISSN: 1432-2161
    Keywords: Key words CT ; MRI ; Temporomandibular joint ; Temporal bone

    Notes: Abstract  Objective. During routine MR imaging of temporomandibular joints we have observed that an area of low signal is sometimes identified within the temporal bone overlying the glenoid fossa on proton-density sequences. This finding at times simulates a mass. CT in this situation has demonstrated marked pneumatization of the mastoid air cell extending to that portion of the temporal bone overlying the glenoid fossa. We undertook a clinical study to determine the frequency and appearance of such a finding. Design and patients. We reviewed the images of 12 patients who underwent both MR and CT examinations of their temporomandibular joints. The authors, by consensus, graded all 24 joints using a four-point scale for the presence and appearance of a low-signal area overlying the glenoid fossa on the MR images prior to seeing the corresponding CT images. We then compared our grading with the findings on CT to assess for the presence and extent of pneumatization of the temporal bone overlying the glenoid fossa. Results. Of the 24 joints reviewed there was identical extent of low signal on MR imaging and extent of pneumatization on CT in 22 of 24 joints. In two of the 24 joints assessed there was overestimation of pneumatization due to extensive sclerosis secondary to surgery. Conclusion. The findings of an area of low signal overlying the glenoid fossa on a T2-weighted scan of a nonoperative temporomandibular joint is often due to extensive temporal bone pneumatization of the mastoid air cells. Recognition of the nature of this finding will avoid mistaking it for a fibrous or osseous lesion. Patients with previous operative history may, however, require further investigation with CT.

    Popliteal vascular malformation simulating a soft tissue sarcoma (1999)

    Notes: Abstract  Differentiation of vascular abnormalities from soft tissue sarcomas may be difficult on clinical grounds, but is usually possible on imaging criteria. We report the MRI and digital subtraction angiography (DSA) findings in a patient presenting with a mass behind the knee. We discuss differentiating features and review the literature of similar cases.

    Intraneural synovial sarcoma (1997)
    Springer

    Topics: Medicine
    Notes: Abstract  This report describes and discusses the clinical, MRI, and pathologic findings in a case of synovial sarcoma arising within a peripheral nerve. Intraneural origin of synovial sarcoma is very unusual, and the MR imaging appearance of this condition has not been previously reported. MR imaging was valuable, as it showed the intraneural location and extent of the tumor, but it did not allow a specific histologic diagnosis.
