Pituitary Apoplexy, Meningitis and Cerebral Infarction - A Perplexing Trifecta

Pituitary apoplexy (PA) is a clinical diagnosis comprising a sudden onset of headache, neurological deficits, endocrine disturbances, altered consciousness, visual loss, or ophthalmoplegia. However, clinically, the presentation of PA is extremely variable and occasionally fatal. While meningitis and cerebral infarcts are themselves serious diseases, they are rarely seen as manifestations of PA and are exceedingly rare when present together. We present the case of a 20-year-old male with a rapid progression of symptoms of meningitis, PA and stroke. The present article seeks to emphasize a rare manifestation of PA with an attempt to understand the intricacies of its evaluation and management.

Apoplejía hipofisaria en posoperatorio inmediato de cirugía cardiaca: a propósito de un caso / Postoperative pituitary apoplexy: case report after a cardiac surgery

Pituitary apoplexy is caused by ischemia or hemorrhage and is considered a medical emergency. A percentage of undiagnosed pituitary adenomas may be diagnosed in the postoperative period of cardiac surgery. The clinical picture is a consequence of the increase in pressure which causes compression on cerebral structures (optic chiasm, cranial nerves) and hormonal deficit. We present a clinical case of a 69-year-old Caucasian male, who debuted with a clinical syndrome of the left cavernous sinus in the immediate postoperative period of cardiac surgery. Clinical and imaging studies (MRI) confirmed the diagnosis of pituitary apoplexy. The condition was solved satisfactorily with replacement therapy. She underwent urgery sixth days later due to persistence of visual symptoms.

La apoplejía hipofisaria se produce por un infarto o una hemorragia en dicha glándula y se considera una emergencia médica. Un porcentaje de adenomas hipofisarios no diagnosticados debutan clínicamente así, pudiéndose producir en el postoperatorio de cirugía cardiaca. El cuadro clínico es consecuencia del aumento de presión y volumen en el interior de la silla turca, lo que origina compresión de las estructuras cerebrales colindantes (quiasma óptico, silla turca, nervios craneales, etc.) y déficit hormonal. Presentamos un caso clínico de un varón de raza caucásica de 69 años, el cual debuta con un síndrome clínico de seno cavernoso izquierdo en el posoperatorio inmediato de una cirugía cardiaca. La clínica y los estudios de imagen (RMN) confirmaron el diagnóstico de apoplejía hipofisaria. El cuadro se resolvió satisfactoriamente con tratamiento esteroideo sustitutivo y cirugía al sexto día del inicio de los síntomas por persistencia de los síntomas visuales.

Post operative 'pituitary apoplexy' in giant pituitary adenomas: a series of cases.

This is report on four cases of giant pituitary tumors that developed postoperative pituitary apoplexy after they had undergone a partial tumor resection. Three patients had undergone surgery by a transsphenoid route and one patient underwent surgery by transcranial route. Postoperative CT scan showed hemorrhagic expansion of residual tumor mass. All the four patients were re-explored transcranially and hemorrhagic swelling of the tumor was observed. In three cases, the tumor had swollen to a size greater than twice the original tumor. All the four patients had a fatal outcome.
