Aim. To evaluate soft tissue masses of the hand with magnetic resonance imaging (MRI) and ultrasonography (USG) and to correlate imaging findings with pathological findings.Material and Methods. Thirty-five patients with soft tissue masses of the hand were evaluated with high resolution USG and contrast enhanced MRI of the hand, prospectively over a period of 2.5 years. The radiological diagnosis was then compared with cytology/histopathology.Results. There were a total of 19 (55%) females. The mean age was 27.45 ± 14.7 years. Majority (45%) of cases were heteroechoic. Four cases were predominantly hyperechoic. These were later diagnosed as lipomas. Four cases were anechoic (diagnosed as ganglions). Only four lesions showed hyperintense signal on T1-weighted images. Out of these, 3 were lipomas and one was cavernous haemangioma. Three lesions were hypointense on T2-weighted images. All these lesions were diagnosed as giant cell tumor of the tendon sheath. A correct diagnosis was possible on MRI in 80% of casesn=28.Conclusion. MRI provides specific findings for diagnosis of certain soft tissue lesions of the hand. Ultrasonography allows accurate diagnosis of hemangioma/vascular malformations. However, in most conditions, imaging findings are nonspecific and diagnosis rests on pathologic evaluation.

AbstractThe vast majority of soft tissue masses are benign. Benign lesions such as superficial lipomas and ganglia are by far the most common soft tissue masses and can be readily identified and excluded on ultrasound (US). US is an ideal triaging tool for superficial soft tissue masses. Compared with magnetic resonance imaging (MRI), High-resolution US is inexpensive, readily available, well tolerated, and safe. It also allows the radiologist to interact with the patient as a clinician. In this review, we describe and illustrate the lesions with typical (diagnostic) US features. When the appearances of the lesion are not typical as expected for a benign lesion, lesions are deep or large, or malignancy is suspected clinically, MRI and biopsy are needed. The management of suspicious soft tissue tumors has to be carefully planned by a multidisciplinary team involving specialized surgeons and pathologists at a tumor center.

Chapter 122 covers US of the wrist and hand. US is gaining popularity as a useful modality for imaging wrist and hand pain, providing soft tissue resolution superior to MRI, with the additional benefits of real-time imaging, ease of comparison to the contralateral side, and dynamic imaging. US provides excellent visualization of tendons and the small joints of the hand. Peripheral nerves are easily identified and assessed with US with resolution surpassing MRI. Median nerve entrapment can be quickly and easily evaluated when carpal tunnel disease is suspected. Dynamic evaluation allows further assessment for the presence of Stener lesion, sagittal band and annular pulley injuries, and for tendon subluxation. US easily shows joint effusions, osteophytes, erosions, and synovial hypertrophy when arthritis is suspected. Soft tissue masses, such as ganglion cysts or giant cell tumor of the tendon sheath, are accurately imaged with US.

Background: The imaging presentation of primary bone lymphoma is unclear. Objectives: The present study aimed to investigate the imaging presentations of primary bone lymphoma especially a specific “floating-ice” sign. Patients and Methods: Forty one patients with primary bone lymphoma confirmed by pathology with 27 males and 14 females and an age range of 2 - 76 (mean = 40) years were enrolled. The clinical and imaging data were analyzed. Results: The tumor involved long bones in 17 cases, flat bones in 12, spine in eight and irregular bones in four cases. The imaging presentations were divided into five types: infiltrative type in nine cases (22%), osteolytic in 14 cases (34.1%), osteosclerotic in four cases (9.8%), mixed in 11 cases (26.8%) including four cases with a “floating-ice” sign and cystic in three cases (7.3%). In plain radiography, only three of four long bone lesions in children had a varying degree of periosteal reaction. Among 20 cases with CT scanning, sixteen had soft tissue masses, seventeen had ill-defined margins, and three had well-defined margins with sclerotic rims. Among twelve patients with MRI, ten had soft tissue masses with well-defined margins. MRI demonstrated a greater extent of lesion than CT. In MRI T1 weighted image (T1 WI), isointense signal was seen in three cases, hypointense signal in five and mixed signal in four. In T2 WI, isointense and hypointense signal was detected in five cases, hyperintense signal in three and mixed hyperintense signal in four. Conclusion: Primary bone lymphoma occurs most frequently in long and flat bones as infiltrative osteolytic destruction, and combined plain radiographs, CT and MRI help obtain a correct diagnosis.

Abstract Objectives To review the clinical and imaging data of spinal giant cell tumour of the tendon sheath (GCTTS) to improve our understanding of the disease. Methods The imaging findings, clinicopathological features and clinical outcomes of 14 patients with pathologically confirmed spinal GCTTS were analysed retrospectively. Results All 14 patients had a single spinal lesion, including ten cervical vertebra lesions and four thoracic vertebra lesions. CT scan findings: The lesions showed osteolytic bone destruction and were centred on the facet joint, eroding the surrounding bone with a paravertebral soft tissue mass. MRI scan findings: all the lesions manifested predominantly as isointense or hypointense on T1-weighted imaging (T1WI). On T2-weighted imaging (T2WI), eight lesions were hypointense, and four were isointense. The remaining two lesions showed slight hyperintensity. The enhanced scans of eight lesions showed moderate to marked homogeneous or heterogeneous enhancement. PET/CT findings: Among the five patients who underwent PET/CT, three presented lesions with well-defined, sclerotic borders, and the uptake of 18F-FDG was markedly increased. One lesion showed an ill-defined border and an uneven increase in 18F-FDG uptake with an SUVmax value of 8.9. A recurrent lesion was only found on PET/CT 45 months after surgery and the SUVmax was 5.1. Conclusions Spinal GCTTS is extremely rare. Osteolytic bone destruction in the area of the facet joint with a soft tissue mass and hypointensity on T2WI images are indicative of the spinal GCTTS. GCTTS shows high uptake of 18F-FDG, and PET/CT is helpful in detecting recurrent lesions.

Abstract Background: To analyze the imaging features of desmoplastic fibroma of bone (DFB) for correct diagnosis. Methods: The plain radiography, computed tomography (CT) and magnetic resonance imaging (MRI) of 20 patients with DFB were retrospectively analyzed. Results: Twenty patients with DFB were retrieved including eleven males and nine females with an age range of 2-52 years (median 27). The DFB involved the femur in six patients, ilium in five, tibia in four, humerus in two, lumbar vertebra in one, radius in one, and calcaneus in the remaining one. DFB was common in the metaphysis of long bones could involve the diaphysis and epiphysis. The imaging presentations were divided into four types: the cystic expansile destruction, osteolytic destruction, mixed destruction, and paraosseous destruction. CT value was 30 -60 Hu in the lesion area (6 cases CT value＞45Hu). MRI had low mixed signals on T1WI and high mixed signals on T2WI. Soft tissue masses might be present in DFB. Conclusions: DFB is a rare tumor with strong local aggressiveness, imaging presentation of cystic bone destruction, low signals on T1WI and T2WI in the lesion, which are helpful for diagnosis of the disease and differentiation from other ones.

Introduction. Chondromas are uncommon benign tumors of cartilaginous origin. Although chonodroma of the jaw is extremely rare, the commonly involved are the anterior portion of the maxilla, condyle and coronoid process. A chondroma is a painless, slow growing tumor causing destruction and exfoliation of teeth. On a radiograph, the tumor appears as a cyst-like radiolucent lesion, while some are sclerotic. The borders are usually ill-defined. Irregular calcifications may be seen with radiolucencies and then it is an osteochondroma. Material and Methods. We present a patient with a resected and histologically proven chondroma of the skull base and maxilla. A 65-year-old female was admitted to our clinic with swelling and breathing difficulties. MRI showed a large soft tissue mass of the skull base and maxilla. Clinicopathological and radiological features were examined by computed tomography (CT) and magnetic resonance imaging (MRI). Discussion and Conclusion. Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor that often occurs in the metaphyses of proximal tibia, proximal and distal femur and small bones of the foot. The differential diagnosis is wide and includes simple or aneyrismal bone cyst, giant cell tumor, nonossifying fibroma, fibrous dysplasia, enchondroma, chondroblastoma, eosinophilic granuloma and fibrous cortical defect. Our case demonstrates an uncommon occurrence in the maxillary sinus: CMF with nasal, pterygoid and orbital infiltration. In the diagnosis of an intracranial chondrocytic tumor, it is important to distinguish it from enchondroma and chondrosarcoma. MR provides a detailed assessment of soft tissue masses of the craniofacial region, while CT offers superior analysis of bone structure involvement. The present case underlines the importance of MR examination in the diagnosis of soft tissue masses in the craniofacial region.

Angiolipoma is a type of lipoma, a benign soft tissue tumor. It is distinguished by the excessive degree of vascular proliferation and the presence of mature adipocytes. It occurs commonly on the trunk and extremities. Angiolipomas larger than 4 cm are classified as “giant,” and due to their size, histological evaluation is necessary to exclude malignancy. We report a case of a male patient who suffered from a giant noninfiltrating intramuscular angiolipoma which formed after venipuncture in the antecubital fossa. Clinical examination showed a palpable painless soft mass. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a giant angiolipoma on the right forearm. Surgical removal of the mass was performed, and the biopsy was negative for malignancy. To the best of our knowledge, this is the first report in the literature of posttraumatic intramuscular angiolipoma. Physicians and orthopedic/general surgeons should be aware of the possibility of soft tissue masses in a posttrauma situation.
