SPONTANEOUS RESOLUTION OF A NONFUNCTIONING PITUITARY ADENOMA OVER ONE-MONTH PERIOD: A CASE REPORT

Area of Science:

• Endocrinology
• Neuroimaging
• Neurosurgery

Background:

• Spontaneous resolution of nonfunctioning pituitary adenoma following hemorrhagic apoplexy is a rare phenomenon with an unknown cause.
• Pituitary apoplexy, characterized by sudden hemorrhage or infarction within a pituitary adenoma, can lead to severe symptoms and hormonal dysfunction.

Observation:

• A 54-year-old male presented with acute headache, vomiting, and sensory sensitivities, indicative of pituitary apoplexy.
• Initial imaging revealed a sellar tumor with signs of hemorrhage, alongside hypogonadism.
• Conservative management with dexamethasone led to symptom resolution.

Findings:

• Serial magnetic resonance imaging (MRI) confirmed hemorrhagic apoplexy of the pituitary adenoma.
• A follow-up MRI one month later showed complete disappearance of the adenoma, with a normal pituitary gland.
• This represents the shortest reported interval for spontaneous pituitary adenoma remission.

Implications:

• The case underscores the potential for rapid spontaneous remission of pituitary adenomas after apoplexy.
• Conservative management may be a viable first-line approach for pituitary apoplexy, especially without significant neurological compromise.
• This finding challenges the immediate surgical approach in select cases, advocating for a watchful waiting strategy.
