ABSTRACT
Objective: To report an unusual combination of paraglenoid labral cyst and labral tear with chondral defect of the humeral head
Clinical Presentation and Intervention: A 34-year-old man presented with right shoulder pain. Conventional MR imaging showed paraglenoid labral cyst. MR arthrography revealed a humeral chondral defect and labral tear associated with paraglenoid labral cyst, and a defect of the posterior inferior labrum extending to the superior labrum and humeral chondral defect. The patient underwent arthroscopic surgery
Conclusion: This case showed the importance of MR arthrography in a case that involved an unusual combination of paraglenoid labral cyst and labral tear with chondral defect
ABSTRACT
Objective: Our aim was to report the importance of an awareness of renal artery variations if surgical procedures are indicated in this region
Presentation and Intervention: A 41-year-old female patient was admitted to our hospital for preoperative staging of the rectum carcinoma. A computed tomography [CT] scan clearly revealed the presence of normally positioned small right and left renal arteries, and a large aberrant renal artery originating from the distal abdominal aorta in a case with a horseshoe kidney [HSK]. A multidetector CT angiography was performed using a 256-detector row CT scanner to obtain an image of vascular structures and associated pathologies
Conclusion: In this patient with HSK, the left renal vein compression was unusual and the CT examination provided a good delineation of vascular and urinary tract anomalies
ABSTRACT
The purpose of this review was to demonstrate magnetic resonance (MR) arthrography findings of anatomy, variants, and pathologic conditions of the superior glenohumeral ligament (SGHL). This review also demonstrates the applicability of a new MR arthrography sequence in the anterosuperior portion of the glenohumeral joint. The SGHL is a very important anatomical structure in the rotator interval that is responsible for stabilizing the long head of the biceps tendon. Therefore, a torn SGHL can result in pain and instability. Observation of the SGHL is difficult when using conventional MR imaging, because the ligament may be poorly visualized. Shoulder MR arthrography is the most accurately established imaging technique for identifying pathologies of the SGHL and associated structures. The use of three dimensional (3D) volumetric interpolated breath-hold examination (VIBE) sequences produces thinner image slices and enables a higher in-plane resolution than conventional MR arthrography sequences. Therefore, shoulder MR arthrography using 3D VIBE sequences may contribute to evaluating of the smaller intraarticular structures such as the SGHL.
