Intracranial abscess developed after ganciclovir treatment: A case report.

In this report, we examine severe neutropenia secondary to ganciclovir treatment and associated intracranial abscess in a patient with respiratory insufficiency who required intubation due to cytomegalovirus (CMV) pneumonitis. Secondary neutropenia is a condition encountered more frequently than primary neutropenia, and additional risk factors may lead to vital complications, independent of the presence of additional risk factors.
