Paraspinal cervical calcifications associated with scleroderma.

Although soft tissue calcifications are well known to occur as a late manifestation in scleroderma, symptomatic paraspinal calcinosis is very rare. Clinically, patients present with focal neck pain, weakness or radiculopathy, and decreased range of motion of the neck. We describe the imaging features of a rare case of cervical paraspinal calcinosis in a 74-year-old woman with long-standing scleroderma. Standard radiography is usually sufficient to confirm the diagnosis, but CT-scan allows a more precise location of the calcifications around the facet joints, sometimes with associated erosions. The advantage of MRI is to evaluate the possible intraspinal extension of the calcifications in case of focal neurological symptomatology.

Unusual musculoskeletal manifestations of Lyme disease.

We report on the imaging features of musculoskeletal abnormalities in a 52-year-old woman suffering from Lyme disease presenting with acrodermatitis chronica atrophicans (ACA). The patient developed recurrent attacks of migratory asymmetrical oligoarthritis, involving articular and peri-articular structures, including the metatarsophalageal (MTP) joints, scapular bone, thoracic spine, elbow, gluteal area, knee, ankle and metacarpophalangeal (MCP) joints. Six months after the first symptoms, Magnetic Resonance Imaging (MRI) showed bone marrow oedema within the proximal phalanx of the right fifth toe, adjacent to an ACA rash. A year after the onset of the disease, swelling at the right scapular region occurred, and MRI showed osseous, periosteal and soft tissue involvement of the superior margin of the right scapula and adjacent rib. On MRI of the spine, there was bone marrow infiltration with irregular delineation of the anterior corner of the thoracic vertebrae 4 to 6, corresponding to an osteoblastic bony lesion on radiographic examination. This case report is unique, because MRI documentation of bony abnormalities and periarticular soft tissue swelling, accompanying an attack of ACA has never been reported previously. Moreover, involvement of the osseous spine and the scapular bone have never been described in the radiological literature.

Accessory navicular bone: not such a normal variant.

The accessory navicular is often erroneously considered as a normal anatomic and roentgenographic variant. Three distinct types of accessory navicular bones have been described. The type 2 and 3 variants have been associated with pathologic conditions such as posterior tibial tendon tear and painful navicular syndrome and therefore should not be arbitrarily dismissed as a roentgenologic variant in a symptomatic patient. The pathogenesis and radiologic findings are discussed and illustrated.

Imaging of tumours of the foot and ankle.

The general presentation of osseous and soft-tissue neoplasms of the foot and ankle is not different from lesions encountered in other parts of the body and imaging features may be nonspecific. Some lesions, however, have a predilection for the foot and ankle and may have typical imaging features, such as plantar fibromatosis or intraosseous lipoma. This presentation aims to give an overview of bone and soft-tissue tumours of the foot and ankle and to discuss the strength of each imaging modality in the diagnosis.

MR imaging of intra-osseous hemophilic pseudotumor: case report and review ofthe literature.

Hemophilic pseudotumor (PT) is a very rare complication of hemophilia consisting of a chronic, encapsulated, hemorrhagic fluid collection occurring both in the soft tissues and/or bone. Radiological features of osseous hemophilic PT are nonspecific and mimic several other benign or malignant bone tumors, or infectious processes. Magnetic Resonance Imaging (MRI) findings of PT involving the bone are only rarely described. The appearance on MRI seems non-specific, but invariably there are heterogeneous low- and high-signal intensity areas on both pulse sequences, reflecting the presence of blood products in various stages of evolution. Although the diagnosis is usually made on the location of the lesion and by the knowledge of the underlying disease, the radiologist should be aware of the imaging characteristics, in order to avoid misinterpretation as a tumoral or infectious lesion, as biopsy of these lesions is contraindicated.

Proceedings of the SRBR-KBVR Osteoarticular section meeting of October 18, 2003 in Antwerp--part two: imaging of foot anomalies.

Many conditions may produce pain in the foot region, including congenital or developmental anomalies, (micro-) traumatic or overuse syndromes, osteonecrosis, tumoral conditions, infectious and inflammatory disorders. The purpose of this review is twofold: to discuss the imaging features of a number of pathologic entities that elicit foot pain as a primary symptom and to comment which imaging technique should be used as the first modality.

Imaging anatomy of the ankle.

The purpose of this short review is to give an overview of the normal imaging anatomy of the ankle and the foot, required to understand pathologic conditions. The anatomy of the ankle and foot reflects the specific needs of the complex biomechanics of walking and running. Therefore, a short discussion of the biomechanics will precede the description of the ankle anatomy. For didactical reasons, the anatomic structures of the ankle and foot will be divided into medial, lateral, anterior and posterior compartments to help the reader conceptualise the particularly complex anatomy, and to describe the different structures in relation to each other. In a the second part the normal variants, which should not be interpreted as pathologic changes, will be discussed.

MR imaging of the postoperative ankle.

Although MRI of the ankle has become a routine diagnostic method to cope with pathologic conditions of the ankle, the literature on postoperative evaluation of the ankle by imaging is very scarce. In this short course, the basic principles on surgical reconstruction techniques of ankle ligaments and tendons will be reviewed. The value of imaging--with emphasis on MRI--in depicting postoperative complications will be discussed as well.

Ankylosing spondylitis: what remains of the standard radiography anno 2004?

In this review, the radiographic features of ankylosing spondylitis of the axial skeleton will be discussed shortly. Three pathologic processes, including inflammation, bony repair and ossification occurring consecutively or simultaneously, will contribute to the radiographic picture of ankylosing spondylitis. Typical target sites at which these processes take place are the synovial joints, discovertebral joints and ligamentous attachments or entheses of the axial skeleton.

Congenital abnormalities of the osseous spine: a radiological approach.

The spine may act as a useful window to the diagnosis of many congenital malformations syndromes and skeletal dysplasias. However, radiological identification of these syndromes remains a difficult task, because there are so many syndromes and dysplasias to remember. Moreover, many spinal abnormalities are non-specific and there is much overlap between different genetic and congenital disorders. Consequently, many radiologists cringe when these topics are discussed. The purpose of this short review is to provide the general radiologist a workable primer for systematic analysis of spinal abnormalities encountered in genetic disorders, which may be helpful in (differential) diagnosis.
