Haemorrhage in pituitary tumours

Area of Science:

• Endocrinology
• Neurosurgery
• Pathology

Background:

• Pituitary adenomas are common tumors, and hemorrhage within them can lead to significant clinical complications.
• Understanding the incidence and characteristics of pituitary adenoma hemorrhage is crucial for diagnosis and management.

Purpose of the Study:

• To investigate the incidence, clinical presentation, histological features, and treatment outcomes of hemorrhage in pituitary adenomas.

Main Methods:

• Retrospective analysis of 320 verified pituitary adenomas.
• Classification of hemorrhage based on clinical features, operative findings, and patient history.
• Histological examination for tumor characteristics.
• Review of computed tomography (CT) scan findings.
• Evaluation of treatment outcomes for transcranial surgery.

Main Results:

• Hemorrhage was identified in 18.1% (58/320) of pituitary adenomas.
• Hemorrhagic tumors frequently exhibited large size, recurrence, invasiveness, malignant changes, increased vascularity, and sinusoidal patterns.
• The majority of patients with hemorrhage were hypopituitary (53.4%), while 39.6% had no apparent endocrine deficit.
• CT scans aided in early preoperative diagnosis of hemorrhage.
• Transcranial surgery was an effective treatment modality.

Conclusions:

• Hemorrhage is a significant complication in pituitary adenomas, often associated with aggressive histological features.
• Early diagnosis using CT scans and effective surgical management, particularly transcranial surgery, are vital for improving patient outcomes.
