BACKGROUND AND PURPOSE Occasionally, diving ranulas may attain large dimensions (giant ranula); gross involvement of the submandibular and parapharyngeal spaces makes differentiation from other cystic neck masses, particularly cystic hygroma, difficult. As diving ranula and cystic hygroma are managed with different surgical approaches, avoidance of this pitfall is critical. Our purpose was to r...

A 56-year-old woman presented with a 2-year history of right hemispheric focal seizures confirmed by electroencephalography. Physical and neurologic examination revealed only a mild left-central facial nerve paresis. CT showed a cystic right parasagittal tumor with an enhancing wall (Fig. 1 A). The thin wall was of varied thickness but without focal nodularity. The cystic tumor abutted the falx...

aneurysmal bone cyst (abc) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. treatment methods include surgical excision and curettage with or without bone grafting. we report a proximal femu...

Pancreatic cystic lesions are usually inflammatory pseudocysts (90%) or, infrequently, neoplastic processes [1]. A lymphoepithelial cyst (LEC) of the pancreas is a rare true cyst of this organ and is lined by squamous epithelial tissue surrounded by lymphoid tissue with germinal centers [2]. This rarely seen lesion should be considered in the differential diagnosis of cystic neoplasms of the pa...

Background: Cystic and cavitary lung cancer (CCLC) is infrequently observed on computed tomography (CT) scans; however, its diagnosis often overlooked or delayed. Objectives: The current study aimed to investigate the CT 18F-fluorodeoxyglucose positron emission (18F-FDG PET) features of CCLC. Patients Methods: A total 809 patients who underwent tumor resection were examined in this study, prese...

Lymphangioma is a benign infiltrative malformation of the lymphatic channels. Cystic lymphangioma or cystic hygroma is a subtype of lymphangioma which exhibits large macroscopic cystic space histologically. The cause of cystic hygroma is believed to be developmental defect or primary Multilocular cystic malformation of dilated lymphatic channels. Cystic hygroma is a common and distinct entity t...

Background: Cystic lesion in the neck originates from lymph nodes, skin appendages, soft tissues, salivary gland or developmental anomalies of like branchial cleft. Present study has been designed to know anatomical site cystic swelling, dividing them cystic, inflammatory, benign, and malignant groups.Methods: FNAC was done using 22 gauge needles. The aspirated material smeared on slide stained...

Background: Phyllodes tumors (PTs) are uncommon biphasic fibroepithelial neoplasms of the breast occurring in elderly females with a peak incidence between 45 and 49 years. Depending on various histological criteria, they are subdivided into benign, borderline, and malignant forms. Metaplastic changes occur, but are quite infrequent and cystic squamous metaplasia is ve...
