Cervical Thymic Cyst - An Overlooked Entity
Malaysian Journal of Paediatrics and Child Health
Thymic cysts are one of the rare causes of neck masses in the paediatric age group. Patients may complain of neck swelling either central or lateral neck swelling. There is difficulty in diagnosing a cervical thymic cyst as it may mimic a branchial cleft cyst or a cervical lymphangioma. Definitive diagnosis of a thymic cyst requires histopathological examination of thymic tissue. We report a case of a 6-year-old girl who presented with painless lateral neck swelling for 2 months duration. Computed tomography (CT) scan showed a left branchial cyst with retropharyngeal extension. The patient underwent complete excision of the mass and histological examination was reported as a cervical thymic cyst. Postoperatively, she was able to be discharged after serial follow-ups with no signs and symptoms of recurrence.

Kierownik: prof. dr hab. M. A. Karolczak The Authors of this study present a case of a 13-month old child subjected to surgical intervention for a cervical thymic cyst. The origin of lesions in children is usually associated with remnants from the development of the fetal thymus gland. When the tumor attains significant size, especially in the presence of clinical symptoms, such as respiratory disturbances and problems with feeding, surgical management is required. In spite of the rarity of thymic cysts, it should be considered in cases of differential diagnosis for neck tumors in children. Proper diagnosis is usually possible after the histopathological evaluation of removed tissues. The cervical approach enables removal of the entire lesion, even if partially localized in the thoracic cavity.

INTRODUCTION: Isolated Thymic cysts are very uncommon lesions and are believed to account for approximately 3% of all anterior mediastinal masses (1). Thymus is derived from 3 rd pharyngeal pouches with only a small contribution from 4 th pharyngeal pouches. CASE REPORT: An upper lateral neck swelling on the left side of short duration which was diagnosed pre-operatively as, branchial cyst, in a 7 year female child. There were no symptoms of pain or obstruction. Excision biopsy was done and the histopathological diagnosis was confirmed as Thymic cyst. Embryological and histological aspect with review of literature has been done.
Symptomatic Cervical Thymic Cyst: A Case Report and Literature Review
Journal of Comprehensive Pediatrics, 2013
Introduction: Ectopic cervical thymic cyst is a very rare cause of neck masses in children. The diagnosis is sometimes very difficult and preoperative, correctly diagnosed thymic cysts in the neck are very low. Case Presentation: We report a 5-year-old boy with a left sided cervical mass and respiratory distress following a common cold, and ultrasound and CT scan revealed a cystic mass in the left neck with extension to the anterior mediastinum, suggesting cystic hygroma. After complete resection of the cyst and its extension, pathology report demonstrated simple thymus cyst. Discussion: Thymic cyst must be considered in differential diagnosis of a young child with a cervical mass.
Cervical thymic cyst: A case report
American Journal of Otolaryngology, 2002
This paper describes the case of a young man who presented with a mass in the left side of his neck. Surgical excision revealed an ectopic thymic cyst. Thymic cyst should be included in the differential diagnosis of neck masses, especially in children. The authors review the embryology, diagnosis, and management of this pathology.

Cervical thymic cysts: CT appearance of two cases including a persistent thymopharyngeal duct cyst
Pediatric Radiology, 1995
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 as a differential diagnosis of an asymptomatic neck swelling especially in children.

Axial CT scans showed a hypodense area with fluid density (5-20 HU) extending from the carotid triangle into the right upper thoracic paratracheal region. It was bounded laterally by the internal Jugular vein, anterolaterally by the sternocleidomastoid muscle, medially by the common ...
Cervical Thymic Cysts in Adults
Thyroid, 2011
Background: Three types of cervical thymic anomalies have been described: ectopia, thymic cyst, and thymoma. Thymic cysts are very rare causes of benign neck masses in adults and are usually not diagnosed before surgery. Their prevalence is less than 1% of all cervical masses, and they are usually noted in childhood. We systematically reviewed the literature concerning cervical thymic cysts (CTCs) in adults. Summary: We identified 36 adult patients with a CTC. Our analysis included age, gender, cyst size, location, type, symptoms, time from cyst appearance, treatment, pathology, and follow-up. The male/female ratio was 4/ 5, the mean age was 36 years. Most of the cysts were asymptomatic masses diagnosed by pathology. In only one case did the differential diagnosis include a thymic cyst. Surgery should be considered the treatment of choice, but the size and location of the lesion and its relationship to nearby vital structures should be defined as clearly as possible preoperatively. Excision can be made via a transverse cervical incision. It may be a demanding procedure because of the close anatomical relationship of the CTCs with the carotid sheath and major nerves of the neck (recurrent laryngeal nerve, glossopharyngeal nerve, hypoglossic nerve, and phrenic nerve), particularly if there is adherence of the CTC with those structures. Conclusions: CTCs are uncommon lesions causing neck swelling and are often misdiagnosed preoperatively. Surgical excision and histological examination of the specimen usually makes the diagnosis. The existence of normal thymus gland in the mediastinum should be confirmed intraoperatively, but this is not critical in adult patients. A CTC should be included in the differential diagnosis of cervical cystic masses.
