  • Diagnostic difficulties of plunging ranula: case series

  • R Jain, R P Morton, Z Ahmad
  • Journal:
    The Journal of Laryngology & Otology / Volume 126 / Issue 5 / May 2012
    Published online by Cambridge University Press:

  • Objectives:

    To evaluate common pitfalls in diagnosing complicated plunging ranula, either due to misidentification of plunging ranula or alternative pathology (i.e. false negatives or false positives, respectively).

    Methods:

    A review of cases of plunging ranula seen in Middlemore Hospital, New Zealand, was performed. Diagnostically uncertain cases were identified and reviewed, taking particular note of clinical, radiological and surgical findings.

    Results:

    From our database, 12 cases were found to have had a complicated diagnosis of plunging ranula. Ten cases were false negatives: four were treated as abscesses, four as simple cysts, one as a thyroglossal cyst and one as a cystic hygroma. Two cases were false positives: one was found to be a thyroglossal cyst and the other a lipoma.

    Conclusion:

    The diagnosis of plunging ranula is usually straightforward, with simple surgical management. Misdiagnosis can lead to recurrence of symptoms and inappropriate management, with the associated risks, complications and frustrations of surgery.

  • Cervico-thoracic teratoma masquerading as lymphatic malformation

  • A case is presented of a nine-month-old male infant who presented acutely with an anterior neck and mediastinum mass compressing the trachea. Radiological assessment by ultrasound, magnetic resonance imaging and computed tomography suggested the nature of the mass to be a lymphatic malformation (cystic hygroma). The excised specimen was revealed as a mature teratoma. The inability to distinguish between lymphatic malformation and teratoma on multi-imaging modalities confers a risk of mismanaging these lesions with the use of sclerotherapy; surgical excision is the necessary treatment. The potential consequences are discussed.
