Insights

A rare venous vascular malformation mimicked sialadenitis in a pediatric patient. Careful review of imaging revealed phleboliths, leading to correct diagnosis and surgical resection of the venous malformation.

Area of Science:

  • Vascular Surgery
  • Pediatric Radiology
  • Otolaryngology

Background:

  • Venous vascular malformations (VVMs) are rare congenital anomalies.
  • Phleboliths, calcified venous thrombi, are characteristic of VVMs.
  • Sialolithiasis, salivary stones, can cause sialadenitis, particularly in adults.

Observation:

  • A pediatric patient presented with a left submandibular mass and symptoms suggestive of sialadenitis.
  • Initial imaging suggested sialolithiasis as the cause.
  • The mass was identified as a venous vascular malformation with phleboliths.

Findings:

  • Phleboliths in VVMs can be mistaken for sialoliths on imaging.
  • Sialoliths are exceptionally rare in pediatric patients.
  • The patient's submandibular mass was definitively diagnosed as a venous malformation.

Implications:

  • Misdiagnosis of VVMs as sialadenitis due to phlebolith mimicry can occur.
  • Early and accurate diagnosis is crucial for appropriate management.
  • Complete surgical resection is the recommended treatment for symptomatic VVMs.
