Although the MR arthrographic findings were similar for type II SLAP lesion and sublabral recess, laterally curved high signal intensity on oblique coronal images, concomitant anterosuperior labral tear, and anteroposterior extension of high signal intensity on axial images were helpful findings in the diagnosis of type II SLAP lesion.

We could detect sternal fractures more effectively with sonography than with conventional radiography and bone scans. In addition, sternal fracture locations showed relatively even distributions, and focal fractures in the manubrium were not easily detected on bone scans.

A ruptured epidermal inclusion cyst visualized by sonography had variable shapes; the sonographic findings can be useful for obtaining a correct diagnosis of a ruptured epidermal inclusion cyst.

When the arthroscopic results were used as the reference standard, our preliminary study revealed that sonography managed to show anterosuperior labral abnormalities, although it had a lesser diagnostic ability than MR arthrography in diagnosing anterosuperior labral tears. Additional investigations including larger numbers of patients are required to determine whether sonography can be an alternative or adjunctive imaging technique for diagnosis of hip labral tears, especially in patients who d

Cysts in the posterosuperior portion of the humeral head (the bare area) were located in the lateral humeral head just posterior to the greater tuberosity. These cysts were lined with collagen connective tissue and were connected to the joint spaces. We suggest that these pseudocysts in the posterosuperior portion of the humeral head may be a normal variant rather than being an abnormal change or vascular channel.

We retrospectively reviewed 2 cases of organizing hematomas and 2 cases of intravascular organizing thrombi and investigated correlations between sonographic and pathologic findings. In all 4 cases, a well-defined hypoechoic heterogeneous mass with surrounding increased echogenicity was evident in the subcutaneous fat layer. Organizing hematomas and thrombi have sonographic features similar to those of benign-looking soft tissue tumors. These lesions should therefore be considered in the differe

OBJECTIVES: We evaluated the sonographic features of superficial-type nodular fasciitis in 9 pathologically proven cases. METHODS: Review of the radiology and pathology databases yielded 14 cases of histologically proven superficial-type nodular fasciitis, which was defined as nodular fasciitis located in the subcutaneous fat layer or outer muscle fascia between the subcutaneous fat layer and muscle. Sonograms were available in 9 patients. Two musculoskeletal radiologists retrospectively reviewe

Sonography can play an important role in the diagnosis of benign, vascularized superficial soft-tissue tumors. Awareness of these findings is important in establishing the correct diagnosis and determining the optimal treatment.

Radiologists need to be aware of the sonographic findings of malignant, vascularized superficial soft-tissue tumor findings and their look-alikes for the differential diagnosis and determining an optimal treatment plan.
