Cervical thymic cyst is a rare clinical entity, with approximately one hundred cases reported in the literature so far. The purpose of this case report is to highlight some certain features, along with an extensive research of the relevant literature. A 6-year-old boy was admitted to the Otorhinolaryngology Department due to the presence of a left-sided, painless, latero-cervical swelling, first observed by his parents 2 weeks ago. Physical examination revealed a painless, well-delineated mass, with no signs of inflammation. No enlarged cervical nodes were present. The mass extended from the mandibular angle, under the sternocleidomastoid muscle, in proximity with the ipsilateral neurovascular bundle. Ultrasound transverse gray-scale panoramic view detected a wellcircumscribed lesion, with fine echogenic foci, appearing in close proximity with the upper pole of the left thyroid lobe and the ipsilateral common carotid artery. Elective surgical intervention with complete mass excision was performed. Histopathological examination confirmed the diagnosis of a cervical thymic cyst. Cervical thymic remnants represent a group of neck masses that pediatricians and pediatric surgeons should consider in differential diagnosis of both cystic and solid neck masses. Most cystic cervical thymic masses are found in the lower third of the anterior neck, extending deep to the sternocleidomastoid muscle, featuring close anatomic relationship with the composites of the ipsilateral carotid sheath. Elective surgery is kept as the treatment of choice, after ruling out the possibility of subject immunologic disturbance.

Introduction: Laparoscopic cholecystectomy is currently regarded as the optimal treatment method for cholelithiasis. Normal anatomy of the biliary tree is reported to be found in only 58% of the population. Duct of Luschka represents a well-known and widely reported anatomic variation of the biliary tree which may lead to bile leakage if injured during hepatobiliary surgery. Methods: We report a case of 71 years old man presented to our department with choledocholithiasis and lap-cholecystectomy was performed. Purpose of this case report is to focus on the clinical significance of Luschka duct injury and its potential to be successfully management with endoscopic ERCP. Results: During laparoscopic cholecystectomy, an ectopic luschka duct alongside inferior border of liver in the VI segment was accidentally injured. We decide to convert to open cholecystectomy and luschka duct ligation was performed. In the 5 th PO day, bile content was detected in the patient drainage. MRCP revealed a Full-thickness maximum intensity projection showing the Luschka ducts feeding a biloma. ERCP was performed in the 6 th PO day and immediate, patient have no signs of bile content in his drainage. Patient was discharged on the 9th PO day. Conclusion: Clinical significance of Luschka ducts, lies on their risk for injury during cholecystectomy. Clinical presentation of patient with po bile leakages varies from asymptomatic to biliary peritonitis. PO identification is feasible with MRCP imaging and can be treated with less invasive techniques such as ERCP.
