RESUMEN
In this article, we present an exceptional case of pituitary apoplexy in which a patient presented with meningeal symptoms of headache, stiff neck, and nausea rather than the classical findings of ophthalmoplegia and/or vision loss. The patient has had 2 similar presentations with cerebrospinal fluid showing neutrophilic pleocytosis, as well as a computed tomography scan showing a prominent pituitary gland. On current presentation, the patient's vital signs were stable and the physical examination was remarkable for nuchal rigidity. Magnetic resonance imaging of the head revealed an expansile pituitary gland lesion measuring 2.0 × 1.7 × 1.5 cm with upward displacement of the overlying optic chiasm. Cerebrospinal fluid showed neutrophilic pleocytosis, low glucose, high protein content, and negative bacterial and fungal cultures. Surgical decompression subsequently revealed findings consistent with pituitary apoplexy. This is the first known case in which a patient had recurrent episodes of meningitis due to pituitary apoplexy in the absence of a clinical deterioration. Early identification of apoplexy masquerading as meningitis will allow early surgical intervention, if necessary, to prevent complications, recurrence, and morbidity. As such, the presence of sterile meningitis in patients with a known pituitary adenoma should be considered for prompt surgical evaluation.
