The differential diagnosis of a lateral cystic neck mass includes branchial cleft cysts and lymphangiomas. Cervical thymic cysts are rare, and thymopharyngeal duct cysts, which maintain a connection to the pharynx, are rarer still. We present an interesting case of a 6 year-old male who developed acute onset of a left-sided neck mass. CT and MRI findings revealed a multiloculated cyst closely a...

BACKGROUND The thymus develops from the third pharyngeal pouch and descends from the neck into the anterior-superior mediastinum. Thus, it is possible to have thymic remnants in the neck, which most often present as a cervical mass during childhood. One type of cystic thymic remnant is the thymopharyngeal duct cyst, a remnant of one of the paired tracts of embryological thymic descent. Thymopha...

Ectopic cervical thymus (ECT) is an uncommon cause for cervical mass in the pediatric age group. Ultrasound and magnetic resonance imaging findings of the mass (located along the thymic descent pathway along the thymopharyngeal tract and has identical echostructure and signal intensities to the native thymus in the superior mediastinum) would lead to the diagnosis. The diagnosis is confirmed by...

Cervical thymic cyst is a rare entity of either congenital or inflammatory origin described infrequently in literature. The asymptomatic nature of the entity and the rarity of the lesion frequently lead to a diagnostic dilemma many times. We present a case of cervical thymic cyst that presented to us as an asymptomatic neck mass that was managed surgically. Cervical thymic cyst should be kept a...

Thymus is a primary lymphoid organ in fish. This gland is situated at the upper most part of the middorsolateral region of the opercular cavity, close to the base of 3 rd and 4 th gill arches. Aplocheilus panchax (Weight-2.5gm. Length-7.5cm.) a fresh water teleost belonging to the Order – Cyprinidontiformes, family – Aplocheilidae is examined under light and transmission electron microscopes (L...

BACKGROUND AND PURPOSE There is wide discrepancy between common clinical and radiologic presentations of branchial sinuses arising from the pyriform fossa and the theoretic course of third and fourth branchial arch anomalies. The purpose of this study was to revisit the clinical presentations and imaging features of such anomalies in children. MATERIALS AND METHODS A retrospective review of i...
