A case of hypophysis with HIV negative cryptococcal meningitis.

The clinical mortality of cryptococcal meningitis (CM) is high. There is no report of hypopituitarism associated with HIV negative CM so far. The patients with hypopituitarism complicated with CM are easy to be misdiagnosed and mistreated. A patient with hypopituitarism and HIV negative CM was admitted to Weihai Municipal Hospital on August 27, 2021. The patient was treated for 18 years after craniopharyngioma with headache for more than 2 months, nausea and vomiting for 4 days. MRI showed abnormal enhancement of the right basal ganglia, edema of surrounding tissue, and multiple striated enhancement of the bilateral cerebellar hemisphere. The smear of cerebrospinal fluid showed a large number of fungi and Cryptococcus. Culture of cerebrospinal fluid showed positive in Cryptococcus. The patient's HIV and syphilis antibodies were negative. The condition of the patient was improved after active antifungal therapy. The clinician should make a definite diagnosis and give early treatment as soon as possible.
