Ultrasound is an accurate tool for diagnosing acute appendicitis. Conservative treatment for uncomplicated acute appendicitis is feasible and safe in children. However, no sonographic follow-up results from children with nonoperatively managed acute appendicitis have been reported.To describe the sonographic appearance of the appendix at follow-up ultrasound and to attempt to identify signs predictive of recurrent acute appendicitis.Children diagnosed with uncomplicated acute appendicitis and treated conservatively in our hospital from 2014 to 2019, and who presented for follow-up ultrasound at 3, 6 and 9 months, were included in our study. Clinical, laboratory and ultrasound data were recorded.By the end of follow-up, 29 (14.2%) of 204 children in the cohort had developed recurrent acute appendicitis and 175 had recovered uneventfully. On follow-up ultrasound, appendiceal diameter measured 6 mm in 56/204 (27.5%) cases at 3 months and in 9/26 (34.5%) at 6 months. After 3 months, 102/204 (50%) children had normal appendiceal diameter on ultrasound. Appendiceal diameter 6 mm was associated with intraluminal fluid or sludge in the appendiceal lumen at 3- and 6-month follow-up (P 0.001, P = 0.002, respectively). Comparing cases with and without recurrence, at 3-month follow-up, appendiceal diameter 6 mm was found in 17/29 (58.6%) cases vs. 39/175 (22.3%), respectively (P 0.001). Appendiceal diameter returned to normal in 12/19 (63.2%) cases in the nonrecurrent acute appendicitis group compared with 2/7 (28.6%) in the recurrent acute appendicitis group (P = 0.05) at the 6-month follow-up. Intraluminal fluid or sludge was detected more frequently in the recurrent acute appendicitis versus the nonrecurrent acute appendicitis group at 3- (P 0.001) and 6-month (P = 0.001) follow-up.Progressive normalization of appendiceal diameter was noted on follow-up ultrasound. The prevalence of both appendiceal diameter 6 mm and intraluminal fluid or sludge were found to be increased in children who later developed recurrent acute appendicitis. Ultrasound appears to be a useful tool for follow-up in children with conservatively treated uncomplicated acute appendicitis and possibly might help predict recurrence.

Patients with systemic sclerosis (SSc) are at increased risk for autoimmune thyroid diseases, but information regarding thyroid nodules and cancer in SSc is scarce. Objectives: To evaluate the thyroid gland in patients with SSc at a single Israeli center.Thyroid workup was conducted in consecutive SSc patients: thyroid-stimulating hormone (TSH), free thyroxine (fT4), anti-thyroid peroxidase, and anti-thyroglobulin antibodies, as well as thyroid ultrasound and fine needle aspiration (FNA) when appropriate.Fifty patients, mean age 51.3 ± 13.5 years (44 women) were evaluated. Ten were previously diagnosed with thyroid disease. Median TSH level was 2.0 (normal range 0.23-4 mIU/l) and median fT4 level was 1.0 (normal range 0.8-2.0 ng/dL). Among the 40 thyroid disorder-naive patients, 3 had subclinical hypothyroidism and 5 had positive anti-thyroid antibodies; 22 (44%) had 1-6 thyroid nodules, which were ≥ 1 cm in 12 (24%). Accordingly, six patients underwent FNA, and five were diagnosed as colloid nodules and one as papillary carcinoma.New cases of clinically significant autoimmune thyroid disease were not detected in our cohort of patients with SSc. Nevertheless, almost half had thyroid nodules. The clinical significance of these findings and their relation to thyroid cancer remains to be determined.

The purpose of this work is to draw attention to the characteristic sonographic features of carotidynia, which, in the context of a typical clinical picture support its diagnosis. Six patients presented with primary symptoms of neck pain and focal tenderness. In all patients, focal wall thickening of the distal end of the common carotid artery was found exactly in the region of tenderness, leading to mild lumen narrowing. Treatment with nonsteroidal anti-inflammatory drugs or glucocorticoids led to full symptom resolution. Carotidynia will often be encountered first on sonography performed for evaluation of neck pain and has a characteristic sonographic appearance.

Partial segmental thrombosis of the corpus cavernosum is an unusual clinical condition. It is characterized by thrombosis within the proximal segment of the corpus cavernosum visualized with radiologic imaging. We report a case of a 56-year-old man diagnosed with computed tomography, sonography and magnetic resonance imaging that revealed a thrombosis in the right proximal corpus cavernosum.
