Although similar findings were found in some lesions, the large histologic variability of NF hampers the definition of a prototype of NF on MRI. However, the MRI appearance of the myxoid subtype is rather characteristic. Histologic findings reflect the different SI characteristics and enhancement pattern on MRI.

This article discusses the range of manifestations of tuberculosis (TB) of the abdomen, including involvement of the gastrointestinal tract, the peritoneum, mesentery, omentum, abdominal lymph nodes, solid abdominal organs, the genital system and the abdominal aorta. Abdominal TB is a diagnostic challenge, particularly when pulmonary TB is absent. It may mimic many other abdominal diseases, both clinically and radiologically. An early correct diagnosis, however, is important in order to ensure proper treatment and a favorable outcome. Modern imaging is a cornerstone in the early diagnosis of abdominal TB and may prevent unnecessary morbidity and mortality. Generally, CT appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis, other than gastrointestinal TB. Barium studies remain superior for demonstrating mucosal intestinal lesions. Ultrasound may be used for follow-up to monitor therapy response. The diagnosis of abdominal TB should be considered if suggestive imaging findings are found in patients with a high index of suspicion.

Desmoplastic fibroma of bone is a very rare benign tumor, which may be locally aggressive. In contrast to the well-documented radiological appearance, the literature on MR imaging features of this tumor is scarce. The MR imaging characteristics in our case are compared to those previously reported. Although there is a considerable overlap in the MR imaging features with other bone tumors, an interesting MR feature of desmoplastic fibroma is the presence of low to intermediate signal intensity foci on T2-weighted images, which radiographically does not correspond to calcifications. This feature may help narrow the differential diagnosis.

The most frequent symptoms were pain and muscle weakness accompanied by waddling gait. Two patients were asymptomatic. Radiologically, the disease can be classified as a craniotubular hyperostosis. Typically, fusiform thickening of the diaphyseal portions of the long bones was seen in all 8 patients, but in 1 patient, metaphyseal involvement was observed as well. Radioclinical abnormalities were most often detected before the age of 30, and were usually more extensive at older age. Radiological abnormalities may precede the clinical signs. Concomitant broadening of the diaphyses of long bones and narrowing of the medullary canal suggest that both an excessive periosteal apposition of bone and a defective resorption of bone at the endosteal side of the long bones exist.

Angiography for late spontaneous hemarthrosis is very effective to exclude or establish vascular malformations and to establish the diagnosis of hypertrophic vascular synovium. Selective arterial embolization seems to be a good therapeutic option as alternative to open or arthroscopic synovectomy.

A 65-year-old woman presented with progressive swelling of the anterior aspect of both legs, the dorsal aspect of the feet (Fig. 1a), and the fingers, together with clubbing of the last (Fig. 1b). These features had been present for 4 years but she had only recently developed discomfort and pain in her feet from pinching shoes. The overlying skin was indurated with red-purple discoloration. A localized nodular thickening sharply demarcated from the surrounding skin surface was seen on the dorsal aspect of both feet (Fig. 1a).The patient's past medical history was unremarkable except for hyperthyroidism of Graves, which she had had for 10 years and for which she had received treatment with iodine-131 on three occasions. The last dose of iodine-131 was administered a year before the present hospital presentation. She was currently euthyroid taking thyroxine replacement therapy.On physical examination the thyroid gland was normal. Marked exophthalmos had been present from the onset of Graves' disease but did not required surgical therapy. On CT scan of the orbit, marked proptosis was confirmed (Fig. 2a), as well as thickening of the extraocular muscles (Fig. 2b).Laboratory examination of the thyroid function revealed a suppressed thyroid-stimulating hormone level and an elevated titer of thyroid stimulating immunoglobulin.Radiographs of the hands revealed a bilateral feathery diaphyseal periosteal reaction on the radial side of the first and second Eur.Abstract Thyroid acropachy is a rare manifestation of autoimmune thyroid disease, in the form of soft tissue swelling of the hands and feet with insidious onset, associated with clubbing and characteristic periosteal reactions. It is usually part of a syndrome consisting of a typical triad of thyroid acropachy, exophthalmos, and pretibial myxedema. The purpose of this case report is to demonstrate the imaging features of this typical triad in a 65-year-oldwoman. This case is the first in which the MRI features of thyroid dermopathy are documented.
