[Late findings on computer tomography after cerebral abscess surgery]

Area of Science:

• Neurosurgery
• Neuroradiology

Background:

• Cerebral abscesses require surgical intervention, but long-term sequelae are not fully understood.
• Post-surgical monitoring is essential to assess treatment outcomes and detect complications.

Purpose of the Study:

• To evaluate long-term CT findings in patients after cerebral abscess surgery.
• To identify factors associated with persistent pathological changes.

Main Methods:

• Computed Tomography (CT) examinations of 10 patients post-cerebral abscess surgery.
• Analysis of imaging findings, including hypodense foci and pseudocysts.
• Correlation of imaging findings with surgical history and complications.

Main Results:

• All patients exhibited hypodense foci on CT scans, with 4 showing pseudocysts.
• Extensive pathological lesions were observed, particularly in patients with relapses or those treated with minimal surgery.
• One pseudocyst demonstrated an expansive effect on the lateral ventricle.

Conclusions:

• Persistent hypodense lesions and pseudocysts are common after cerebral abscess surgery.
• Regular postoperative CT surveillance is vital for early detection of relapses and effective management.
• Even minimal surgical interventions may be associated with significant long-term pathological changes.
