INTRODUCTION Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen). So far, 70 cases of cervical localization of bronchog...

BACKGROUND AND PURPOSE Although the thymus is centered in the mediastinum, often a cervical component can be seen in children and young adults. The frequency of radiologically evident residual cervical thymus in older adults is not known. The purpose of our study was to determine the proportion of adults who have residual cervical thymus visible on contrast-enhanced neck CT. MATERIALS AND MET...

BACKGROUND Surgical site infections are potential complications following open myomectomy. These infections usually develop immediately after the surgery, and are most often located in the myometrium. Pyogenic cervical cysts are rare and have not been previously reported to occur at the site of myomectomy. CASE PRESENTATION A 41-year-old nulligravida Japanese woman was referred to our hospita...

Cervical esophageal duplication cysts are uncommon congenital malformations, and those with air-fluid level are rarely reported. We describe here a case of cervicothoracic esophageal duplication cyst manifesting air-fluid level on Computed Tomography (CT) in a 6-month-old girl. The preoperative diagnosis was suspected as esophageal duplication or abscess. The postoperative pathological diagnosi...

Spinal arachnoid cysts are uncommon benign lesions that occur in the spinal axis, and can cause spinal cord or nerve roots compression and may become clinically relevant. The authors report a 49-year-old woman who presented progressive onset of cervical pain with distal paraesthesia of the upper limbs associated to an intramedullary arachnoid cyst in the mid-cervical spine diagnosed by MRI. Fro...

BACKGROUND Atlantoaxial cysts are rare, and only 46 histologically confirmed cases have been reported. CASE DESCRIPTION A 75-year-old male presented 2 years ago with headache, neck pain, loss of balance, and episodic dysphagia, for which he had undergone posterior cervical drainage of a left-sided atlantoaxial cyst. Although his original symptoms resolved, they recurred 2 years later and were...

A patient with an uncommonly situated congenital intradural arachnoid cyst is reported. The cyst extended from the cervical spinal canal into the posterior cranial fossa and was posterolateral to the spinal cord. The patient's initial complaint was urinary hesitancy. The location of the cyst is unique and the presenting complaint rare.

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

Ectopic thymus tissue in the neck remains infrequently described in medical literature. This paper presents the case of a young girl, who presenting with a soft, fluctuating bulk mass on the left side of her neck. The patient underwent complete excision of the lesion and histological inspection showed an ectopic thymic tissue cyst. Ectopic thymic soft tissue may remain an uncommon finding, but ...
