Objectives: This study aimed to determine the radial styloid osseous changes observed on posteroanterior wrist radiographs of patients with de Quervain’s tenosynovitis who required surgery or conservative treatment. Materials and Methods: The surgically treated group included 24 patients with de Quervain’s tenosynovitis. The conservative treatment group and the healthy control group each comprised 24 age- and sex-matched subjects. We evaluated the presence of bone apposition, periosteal reaction, sclerosis, osteopenia, erosion, and contour bulge in the epiphyseal remnant at the radial styloid. The incidences of abnormal radiographic findings were compared between these three groups. The correlation of radial styloid bony changes with the duration of symptoms was also analyzed. Results: No significant differences were found between the three groups in terms of periosteal reaction, erosion, and contour bulge at the epiphysial remnant. Significant differences were found between the three groups in the incidence of bone apposition, sclerosis, and osteopenia (p< 0.001). Bone apposition incidence in the surgically and conservatively treated groups was significantly higher than that in the control group (p< 0.001). Sclerosis and osteopenia significantly differed between the surgically and conservatively treated groups (p< 0.001, p= 0.002, respectively). No significant association was observed between the duration of symptoms and the radial styloid osseous changes (p> 0.05). Conclusion: We found a variable incidence of abnormal radiographic findings on the radial styloid in patients with de Quervain’s tenosynovitis and asymptomatic individuals. The presence of sclerosis and osteopenia may be potential risk factors for patients who do not respond to conservative treatment and need surgical intervention.

Purpose We aimed to correlate the presence or absence of embolic debris in filter-type embolic protection devices (EPD), which are frequently used during carotid artery stenting (CAS), with possible risk factors and ultrasonographic plaque features.Materials and Methods Eighty patients, who underwent CAS using a filter-type EPD in the period between July 2016 and March 2019, were included in our study. The modified Gray-Weale classification (mGWC) subtypes obtained in the pre-procedural ultrasonographic examinations were recorded. In addition, other patient-related risk factors considered to be related to a distal embolism were recorded. After the procedure the filters were evaluated to detect and examine embolic debris in the pathology clinic. The presence and features of embolic debris in the filters were recorded.Results In the examinations performed after CAS, embolic debris was macroscopically and microscopically detected in 22 (27%) and 34 (42.5%) of the filter-type EPDs, respectively. A significant correlation was found between the change in the mGWC category of stenotic plaques from type 5 to type 1 and the presence of embolic debris in the filter (p < 0.05). Furthermore, a significant relationship was found between stenotic segment length and the presence of embolic debris in the filter (p < 0.05). The presence of embolic debris was not statistically significantly related to predisposing risk factors for atherosclerosis (p > 0.05).Conclusions During CAS, the likelihood of the presence of embolic debris in the EPDs increases as mGWC categories change from type 5 to type 1 and as the length of the stenotic segment increases.

Mondor's disease, or acute thrombophlebitis of superficial veins of the breast, occurs rarely, and little information is available in the medical literature on imaging findings in this disease. We present the case of a 59-year-old woman who underwent evaluation of a palpable, painful cord in her left breast associated with discoloration of the overlying skin. Mammography revealed a 10-cm-long linear density in her left breast. Gray-scale sonography showed a noncompressible, hypoechoic, undulating tubular structure in the subcutaneous fat. Color Doppler imaging revealed no flow signal in this structure, although we observed arterial flow signals adjacent to it. We diagnosed Mondor's disease and treated the patient symptomatically; 6-week follow-up examinations demonstrated resolution of the venous thrombosis. The use of sonography, particularly color Doppler imaging, can aid in diagnosing Mondor's disease and in monitoring its resolution. © 2003 Wiley Periodicals, Inc. J Clin Ultrasound 31:103–107, 2003

Occlusion or stenosis of the superior vena cava, the innominate vein, or both is an important clinical problem that requires prompt diagnosis. To confirm a suspected occlusion, imaging studies revealing the obstruction and the presence of collateral venous routes are needed. Color Doppler sonography (CDUS) is widely used to evaluate suspected venous thrombosis and collateral pathways. We present the CDUS findings in 2 cases of innominate vein occlusion. In case 1, CDUS of the neck and left upper arm, which harbored a permanent hemodialysis access, showed engorged veins in the upper arm, a patent dialysis access, and some collateral veins in the axilla. The subclavian and internal jugular veins were patent, but the flow in the left internal jugular vein was reversed. The left innominate vein was occluded. In case 2, CDUS of the upper arms showed that the veins, the dialysis access in the left upper arm, and the subclavian and jugular veins were patent, but the flow in the left internal jugular vein and in the right subclavian vein was reversed. Collateral veins were seen in the right axillary region. Both innominate veins were occluded. The resulting collateral pathways, ie, retrograde flow in the ipsilateral jugular vein crossing to the contralateral jugular vein through dural sinuses, were confirmed by venography in both cases. © 2002 Wiley Periodicals, Inc.

Lemierre’s syndrome is a rare clinical condition that generally develops secondary to oropharyngeal infection caused by Fusobacterium necrophorum, which is an anaerobic bacteria. A 62-year-old patient with diabetes mellitus presented with internal jugular vein and sigmoid sinus-transverse sinus thrombophlebitis, accompanying otitis media and mastoiditis that developed after an upper airway infection. Interestingly, there were air bubbles in both the internal jugular vein and transverse sinus. Vancomycin and meropenem were started and a right radical mastoidectomy was performed. The patient’s clinical picture completely resolved in 14 days. High mortality and morbidity may be prevented with a prompt diagnosis of Lemierre’s syndrome.
