Introduction The aberrant right subclavian artery (ARSA), also called as lusorian artery (LA) is a developmental anomaly that exists in conjunction with a right non-recurrent laryngeal nerve (NRLN) in almost all cases. The average prevalence of such a vascular variation is estimated as 1%, although, studies have reported very different population means. Up to date, there is no available data on the frequency of this pattern in the Hungarian population. It can be treated as an indirect marker of a NRLN. Any preoperative information on the course of the inferior laryngeal nerves can help surgeons reduce the risk of an iatrogenic injury during thyroidectomies, especially in an environment where access to intraoperative neuromonitoring is limited. Objectives The primary aims were to determine the prevalence of an ARSA, predict the existence of an NRLN in the Hungarian population, and provide demographic analysis. Methods A retrospective, computed tomography-based study was carried out. Demographic description and statistical analysis were provided where applicable. Detected anomalous vasculatures were visualized with 3D segmentation, and images were interpreted. Results The imaging database review identified three patients with ARSA out of 686 eligible recordings, resulting in a frequency of 0.437% in the study population. All three patients were female and had a retroesophageal LA. Two of them had a Kommerell's diverticulum. One patient had common carotid arteries with a single origin. Conclusions The frequency of an ARSA and a concomitant NRLN among Hungarians fits into the results of recent meta-analyses. Preoperative assessment of this anomaly may reduce vocal cord complication rates of thyroidectomies.

Zenker's diverticulum (ZD) is an uncommon disorder that can cause dysphagia with risk of aspiration. While surgical treatment has been the mainstay for many years, endoscopic diverticulotomy has emerged as a first-line option with favorable outcomes. We present the case of a 93-year-old woman with no significant past medical history who was diagnosed with a 6 cm ZD. Due to dysphagia, she experienced significant weight loss and was at risk of malnutrition. She developed aspiration pneumonia and required admission to our center. Given her condition and inability to swallow, a nasogastric tube was placed under radiological guidance for nutritional support pending definitive treatment. On radiographic localization of the ZD, a radiopaque metallic density image was observed that had not been identified in previous imaging. Suspecting a possible retained foreign body in the large diverticulum, a gastroscopy was performed. During the procedure, the ZD was accessed and a 10 mm metallic object was identified. The object was extracted using a Roth net, confirming the suspicion of a foreign body lodged in the ZD. The metallic piece was later identified as a patient's dental prosthesis. After resolution of the aspiration pneumonia, endoscopic-assisted diverticulotomy was performed. The procedure was carried out under deep sedation with cricopharyngeal myotomy without immediate complications. After 48 hours of hospitalization, the patient was discharged without requiring a nasogastric tube for feeding.

BACKGROUND
Sigmoid sinus diverticulum/dehiscence (SSD) is one of the treatable causes of venous pulsatile tinnitus. It can be diagnosed using temporal bone computed tomography (CT) or magnetic resonance angiography/venography (MRA). In cases where patients find their symptoms intolerable, surgical treatment is typically preferred. Here, we have presented a novel surgical technique involving sigmoid sinus re-roofing and have analyzed its feasibility.
METHODS
Between January 2020 and July 2023, approximately 150 patients with pulsatile tinnitus were evaluated at two different tertiary hospitals. Of these, 12 patients were diagnosed with SSD, and seven underwent surgical treatment. Five patients were treated with tailored reroofing (TRR) of the sigmoid sinus and two with transmastoid resurfacing (MRS) of the sigmoid sinus. We compared the Korean tinnitus handicap inventory (K-THI) score, pure tone audiogram (PTA) threshold, and CT findings before and a month after surgeries for these two techniques. The operation time was also analyzed.
RESULTS
In TRR cases, the K-THI score reduced from 55.0 ± 31.4 preoperatively to 4.0 ± 3.0 postoperatively, and the SSD was well-repositioned and covered by a bone chip postoperatively. In MRS cases, the K-THI score reduced from 41.0 ± 9.9 preoperatively to 15.0 ± 21.2 postoperatively, and the SSD was well-covered with bone cement postoperatively. The average surgical time of five TRR and two MRS cases were 77.5 ± 32.5 and 174.0 ± 75.0 min, respectively. No complications were noted.
CONCLUSIONS
Despite the insufficient number of cases, we noted that TRR requires a reasonable amount of time, involves a smaller incision, and may provide favorable outcomes compared to conventional MRS in cases of pulsatile tinnitus associated with SSD.

Meckle's diverticulum is the most common embryological anomaly of the small bowel that is rarely seen in adults. It is caused by the incomplete closure of the vitelline or omphalomesenteric duct. Those who are symptomatic from Meckle's diverticulum have varied clinical presentations, which raise significant challenges with diagnostic and management options. We report a case of a 47-year-old male who presented to the hospital with clinical signs of appendicitis but was found to have perforated Meckle's diverticulitis with faecoliths on computed tomography imaging and laparoscopy. Furthermore, histopathology revealed an ectopic gastric tissue cell type, which is a rare finding. This was definitively managed surgically with laparoscopic resection of Meckle's diverticulum and appendicectomy.

Review
BACKGROUND The gallbladder develops from the hepatic diverticulum during the fourth week of gestation, which also give rise to the liver, extrahepatic biliary ducts, and ventral part of the pancreas. Infrequently, the gallbladder has malformation or disruption in embryogenesis, leading to congenital anomalies. There are various congenital anomalies that can arise in the gallbladder. True or congenital diverticulum of the gallbladder is a rare entity that accounts for only 0.06% of gallbladder congenital anomalies and 0.0008% of cholecystectomies at the Mayo Clinic. CASE REPORT Herein, we report a rare case of a 38-year-old woman who presented to Jubail General Hospital's surgery clinic with right upper-quadrant (RUQ) pain associated with vomiting after meals for 1 month. Laparoscopic cholecystectomy was done and gallbladder tissue was sent to histopathology. Gross examination revealed an outpouching mucosa within the wall that was proven to consist of muscularis and serosa layers under light microscope. Interestingly, xanthogranulomatous inflammation was confined to the diverticulum, unlike the chronic inflammation involving the remaining gallbladder. Based on the above findings, the diagnosis of congenital diverticulum with xanthogranulomatous cholecystitis was made. CONCLUSIONS Gallbladders associated with a true diverticulum are uncommonly found to be buried in the liver, leading to surgical difficulties during cholecystectomy. Therefore, background knowledge of occasional anomalies plays a crucial role in guiding the surgeon to choose the optimal method of management. We also discuss the associated complications that accompany these anomalies, such as non-specific prolonged ailments, acalculous cholecystitis, cholecystitis and cholelithiasis, recurrent cholangitis, and carcinoma of the gallbladder.

BACKGROUND
Urethral diverticulum (UD) is a poorly defined anomaly consisting of an outpouching of the urethra. Management without surgical resection is not previously reported in dogs.
HYPOTHESIS/OBJECTIVES
Report the outcome of male dogs presented for urinary incontinence with UD treated with an artificial urethral sphincter (AUS).
ANIMALS
Eight client-owned dogs with UD treated with an AUS.
METHODS
Multicenter retrospective study. Medical records from male dogs with urinary incontinence were reviewed.
INCLUSION CRITERIA
diagnosis of a UD by retrograde cystourethrography, cystoscopy, abdominal ultrasonography or contrast computed tomodensitometry (CT) or a combination of these modalities, AUS placement, and at least 1 follow-up. Urinary continence score (UCS) was attributed retrospectively.
RESULTS
Median UCS at presentation was 1/5. A contrast cystourethrogram was diagnostic in 8/8 dogs. All diverticula were saccular, and 7/8 were within the prostatic urethra and 1/8 extended up to the membranous urethra. A congenital origin was suspected in 7 dogs and acquired in 1. Concurrent anomalies included renal dysplasia or chronic pyelonephritis (n = 4), bilateral cryptorchidism (n = 3), and pelvic urinary bladder (n = 3). All dogs were poorly/moderately responsive to phenylpropanolamine. Artificial urethral sphincter placement resulted in improvement in continence in all dogs with a median UCS of 4/5 (5/5 in 2/8 dogs, 4/5 in 5/8 dogs, 3/5 in 1/8 dogs).
CONCLUSION
Urethral diverticulum should be considered in male dogs with persistent urinary incontinence not responding to medical management. Artificial urethral sphincter placement is an effective therapeutic option that improved continence scores in all dogs.

Diverticular disease is a major cause of hospitalizations, especially in the elderly. Although diverticulosis and its complications predominately affect the colon, the formation of diverticula in the small intestine, most commonly in the duodenum, is well characterized in the literature. Although small bowel diverticula are typically asymptomatic, and diagnosed incidentally, a complication of periampullary duodenal diverticulum is Lemmel syndrome. Lemmel syndrome is an extremely rare condition whereby periampullary duodenal diverticula, most commonly without diverticulitis, leads to obstruction of the common bile duct due to mass effect and associated complications including acute cholangitis and pancreatitis. Here, we present the first case, to our knowledge, of periampullary duodenal diverticulitis complicated by Lemmel syndrome with concomitant colonic diverticulitis with colovesical fistula. Our case and literature review emphasizes that Lemmel syndrome can present with or without suggestions of obstructive jaundice and can most often be managed conservatively if caught early, except in the setting of emergent complications.
