Transarticular epithelioid hemangioma of the ankle-a case of a rare vascular neoplasm.

Epithelioid hemangioma of the bone is a rare kind of vascular neoplasm posing a diagnostic challenge because of its ability to mimic malignant tumors. We report a case of a fast-growing, talofibular joint-involving epithelioid hemangioma, which was suspectedly initiated by vascular damage due to trauma and arthroscopy. The ankle mass appeared as a lytic lesion on the CT images and as a T1 hypo-, T2 mildly hyperintense, lobulated structure on the MRI scans.

Triple elastofibromas located in the supra- and infrascapular regions-a case report.

We report a case of triple elastofibromas located in the supra- and infrascapular regions. A 61-year-old female with a history of bilateral elastofibroma in the typical subscapular region (6 years before) was admitted for the evaluation of a left-sided suprascapular mass that she had first noted 3 months before. On physical examination, a firm, painless, mobile mass was palpated in the subcutaneous tissue.

Aggressive Angiomyxoma: Imaging Findings in 3 Cases With Clinicopathological Correlation and Review of the Literature.

Aggressive angiomyxoma is a rare mesenchymal tumor with a typical presentation as a slowly growing perineal soft tissue mass in paravulvar and pararectal region in young adult women. We present 3 cases of aggressive angiomyxoma with clinicopathological correlation and describe their main imaging features with emphasis on magnetic resonance imaging, adding useful information about their behavior on dynamic contrast-enhanced sequences and diffusion-weighted imaging and including a comprehensive review of the existing literature.

Medium-term outcome of mosaicplasty for grade III-IV cartilage defects of the knee.

Purpose: To evaluate the medium-term outcome of mosaicplasty for full-thickness cartilage defects of the knee joint in 17 patients.

Methods: Records of 12 men and 5 women aged 16 to 57 (mean, 35) years who underwent mosaicplasty for grade III/IV osteochondral defects in the lateral (n=14) or medial (n=3) femoral condyle were reviewed. 12 of the patients had undergone knee surgeries.

Synthetic resorbable scaffolds for the treatment of isolated patellofemoral cartilage defects in young patients: magnetic resonance imaging and clinical evaluation.

Background: Surgical management of patellar cartilage defects remains controversial. The ideal technique to regenerate hyaline cartilage is not yet defined. However, a synthetic resorbable osteochondral scaffold plug (TruFit CB) seems to offer a treatment option with good results at short-term follow-up, at least in the condylar setting.

Soft tissue solitary fibrous tumor. Imaging findings in a series of nine cases.

Objective: Few articles have been published regarding the imaging characteristics of soft tissue solitary fibrous tumors (SFT). The aim of this study is to describe the radiological features in a series of nine patients and to compare these results with pathological and clinical outcome.

Subjects And Methods: Nine cases of soft tissue SFT, confirmed by an experienced tumor pathologist, were studied with imaging techniques (US and MRI).

Generalized muscle pseudo-hypertrophy and stiffness associated with the myotilin Ser55Phe mutation: a novel myotilinopathy phenotype?

Myotilinopathies are a group of muscle disorders caused by mutations in the MYOT gene. It was first described in two families suffering from limb girdle muscle dystrophy type 1 (LGMD 1A), and later identified in a subset of dominant or sporadic patients suffering from myofibrillar myopathy, as well as in a family with spheroid body myopathy. Disease phenotypes associated with MYOT mutations are clinically heterogeneous and include pure LGMD forms as well as late-onset distal myopathies.

No-reflow phenomenon in cardiac MRI: diagnosis and clinical implications.

Objective: The purposes of this study were to depict the first-pass, delayed contrast enhancement and regional myocardial wall motion abnormalities of no-reflow phenomenon MRI and to review the major mechanisms and significance of this phenomenon in the clinical setting.

Conclusion: Contrast-enhanced MRI is a useful noninvasive technique for determining the presence of microvascular obstruction. No-reflow phenomenon has important prognostic implications, and knowledge of the physiologic mechanism is important to understanding the distribution patterns of enhancement in correlation with the underlying pathologic process.

Lesions of the cardiophrenic space: findings at cross-sectional imaging.

Cross-sectional imaging techniques allow excellent visualization of the cardiophrenic space. Under normal conditions, the cardiophrenic space is occupied by fat, the amount of which is usually increased in overweight individuals. It has been suggested that this fat accumulation correlates with the risk of cardiovascular disease.
