A patient with obstructive hydrocephalus and hiccups developed laryngeal stridor after shunting. An autopsy revealed a calcified ependymoma as the cause.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Obstructive hydrocephalus can present with varied neurological symptoms.
  • Hiccups and laryngeal stridor are rare manifestations of central nervous system pathology.

Observation:

  • A patient presented with acquired obstructive hydrocephalus and intractable hiccups.
  • Following surgical shunting for hydrocephalus, the patient developed severe paroxysmal laryngeal stridor and other vocal disturbances.
  • These symptoms were resistant to all medical management.

Findings:

  • Autopsy examination revealed a calcified ependymoma.
  • The tumor's location and characteristics likely contributed to the observed neurological and vocal symptoms.

Implications:

  • This case highlights the diverse and sometimes paradoxical clinical presentations of brain tumors.
  • It underscores the importance of considering neoplastic processes in the differential diagnosis of refractory neurological and respiratory symptoms.
  • Calcified ependymomas, though uncommon, can cause significant morbidity through mass effect and secondary neurological dysfunction.
