Two massive prolactinomas (pituitary tumors) caused rare neurological symptoms like hemiparesis. This expands understanding of macroprolactinoma effects beyond typical visual field defects.

Area of Science:

  • Neuroendocrinology
  • Neurosurgery
  • Neurology

Background:

  • Macroprolactinomas, a subtype of pituitary adenomas, frequently compress adjacent parasellar structures.
  • Compression of the optic chiasm is the most common clinical manifestation, leading to visual field defects.

Observation:

  • This report details two cases of massive macroprolactinomas.
  • These tumors presented with unusual neurological signs, including hemiparesis.

Findings:

  • Hemiparesis, a weakness on one side of the body, is a previously unreported neurological sign associated with macroprolactinomas.
  • The findings suggest that massive macroprolactinomas can exert pressure on more distant brain structures than previously recognized.

Implications:

  • These cases highlight the potential for macroprolactinomas to cause a broader spectrum of neurological deficits.
  • Further investigation into the mechanisms of distant neurological effects from pituitary adenomas is warranted.
  • Clinicians should consider macroprolactinomas in the differential diagnosis for patients presenting with unexplained hemiparesis.
