OBJECTIVES: Extracapsular extension (ECE) in cervical metastatic lymph nodes remains an indication for adding chemotherapy for patients with oropharyngeal squamous cell carcinoma (OPSCC). The aim of this study is to identify specific imaging characteristics on computed tomography (CT) scan that are predictive of ECE in order to better risk stratify patients preoperatively. MATERIALS AND METHODS: A single cohort study was performed using a prospectively collected database of patients with HPV-related OPSCC who underwent transoral robotic surgery with cervical lymphadenectomy...

REVIEW
Hilal Sahin, Samir Abdullazade, Muzaffer Sanci
Mature cystic teratoma (MCT) is the most common neoplasm of the ovary and includes at least two well- differentiated germ cell layers. Different combinations of mature tissue derivatives with varying arrangements in the tumour cause a wide spectrum of radiological presentation ranging from a purely cystic mass to a complex cystic mass with a considerable solid component. In different imaging modalities, each radiological feature reflects a specific pathologic equivalent that forms because of diverse compositions of histological components...

Intraabdominal lymphangiomas are uncommon; additionally, those affecting the gastrointestinal tract are rare and account for less than 1% of cases. Intussusception caused by a cystic lymphangioma of the small bowel is extremely rare. The patient was a 20-year-old woman who visited our emergency room with a complaint of abdominal pain. A computed tomography image revealed ileo-ileal intussusception with a leading hypovascular mass measuring 1 cm in a diameter. Single-incision laparoscopic-assisted ileal resection was performed...

True epithelial-lined cysts are rare forms of adrenal cystic lesions, the pathogenesis of which is still not fully understood. In this report we present a case of an adrenal cyst diagnosed incidentally on imaging in a 31-year-old, previously healthy, obese woman. Due to non-specific hormonal disorders and enlargement of the lesion, a right-sided laparoscopic adrenalectomy was performed. The cyst was lined predominantly by ciliated cuboidal-to-columnar, Müllerian-type epithelium, and focally by flat-to-cuboidal, mesothelium-like lining...

We report the case of a 17-year-old boy with cystic fibrosis (CF) who presented with persistent cough; after starting intravenous antibiotics for Pseudomonas aeruginosa he underwent a computed tomography (CT) scan of the chest. CT revealed extensive consolidation in the right lower lobe with relative bronchus obstruction; the cause of bronchial obstruction was detected in the mediastinal window, corresponding to a bronchial tree-shaped, thick, tenacious mucous plug. This was extracted 48 h after unresponsive bronchial washing and endobronchial instillation of rhDNAse, using foreign-body forceps, with subsequent resolution of cough...

This is a case of a 54-year-old gentleman who presented to an outside hospital emergency department with lower abdominal pain. Computed tomography imaging showed a small amount of intraperitoneal free air and cystic pneumatosis coli. He was admitted, managed conservatively with intravenous antibiotics, and then discharged home after his symptoms improved. Elective laparoscopic sigmoid colectomy was subsequently performed with intraoperative findings of partial sigmoid volvulus and extensive pneumatosis coli of the sigmoid colon...

We report the case of a supra and infratentorial ectopic schwannoma, mimicking a meningioma, that was surgically resected on a 75-year-old man, with a history of progressive visual loss and headaches. MRI was in favour of an occipital, cystic, tentorial-based meningioma extending to the posterior fossa, with signs of intratumoral haemorrhage. This is a unique case because of the rare type of lesion, in a very atypical location, completely unexpected by the preoperative imaging analysis, and to the best of our knowledge it is the oldest patient reported in the literature with this kind of tumour...

Adrenal teratomas are rare neoplasms and there is limited data on their surgical outcomes and long-term prognosis. We aimed to review our institutional experience and compare this to the existing literature on adrenal teratomas in adults and children. An institutional pathology database was searched for cases of adrenal teratoma (June 1956-July 2016). Clinical and imaging data were abstracted from the medical records and pathology slides were obtained for review. In addition, a PubMed search for "adrenal teratoma" from June 1952 to July 2016 was performed to identify reports of primary adrenal teratoma in patients of all ages...
