Accessory cervical thymus presented as a neck mass in an infant. Imaging like MRI and ultrasonography aided in diagnosing this rare ectopic thymus condition.

Area of Science:

  • Pediatric Surgery
  • Radiology
  • Endocrinology

Background:

  • Ectopic thymus, a rare congenital anomaly, can present as a neck mass in infants.
  • Differential diagnosis of pediatric neck masses includes various congenital and neoplastic lesions.

Observation:

  • A 2-month-old boy presented with a unilateral neck mass.
  • Ultrasonography revealed an isoechogenic mass; CT showed a well-defined, mildly enhancing lesion.
  • MRI demonstrated characteristic signal intensities on T1 and T2 weighted images, with low ADC values.

Findings:

  • Histopathological examination confirmed the diagnosis of ectopic cervical thymus.
  • The imaging features, while suggestive of ectopic thymus, also raised suspicion for malignancy.

Implications:

  • Ectopic cervical thymus should be considered in the differential diagnosis of infant neck masses.
  • Advanced imaging techniques such as MRI and ultrasonography are valuable for diagnosis.
  • Early and accurate diagnosis is crucial for appropriate management and to avoid unnecessary aggressive treatments.
