[Postsurgical pituitary apoplexy. Report of two cases]. / Apoplejía tumoral hipofisaria posquirúrgica. A propósito de dos casos.

We report two cases of large macroadenomas that, after a transsphenoidal partial resection, suffered necrosis and swelling of the residual tumor, with increase of its volume, compression of neighboring structures and neurological deterioration. The literature is reviewed looking for possible pathophysiological mechanism and prevention.

Se presentan dos casos de macroadenomas nofuncionantes grandes que, tras su extirpación parcialpor vía transesfenoidal, sufrieron un infarto delresto tumoral residual, con resultado de aumento desu volumen, compresión de las estructuras vecinas ydeterioro neurológico de los pacientes. Ambos fueronreintervenidos por vía transcraneal para conseguirla extirpación completa de sus tumores. Se revisa labibliografía en busca de las claves para prevenir estacomplicación (AU)

[Pituitary adenoma apoplexy after spinal anaesthesia. Report of two cases and review of the literature]. / Apoplejía de adenoma hipofi sario no funcionante tras anestesia espinal. A propósito de dos casos.

Two cases of pituitary apoplexy occurring after spinal anaesthesia are described. Both presented with headache and III par palsy, one of them with additional visual disturbance and hyponatremia. A bibliographical review has been done, looking for early diagnostic keys. We propose the arterial hypotension as a possible pathogenetic mechanism of pituitary adenoma apoplexy.

[Dermoid cyst of the anterior fontanelle in children: clinical significance and differentiation from encephalocele]. / Quiste dermoide de la fontanela anterior en el niño: significado clínico y distinción del encefalocele.

Dermoid cysts of the anterior fontanel present as a tumor lesion that tenses up when the child cries or strains. Their midline position in the skull, the fact that some of these cysts contain clear fluid and the presence of an underlying bone defect, lead the clinician to the erroneous diagnosis of encephalocele, for which they are sent for consultation. We report a series of five of these cysts (3 dermoid and 2 epidermoid) located over the anterior fontanel, remark on their clinical significance, and stress their differential diagnosis from encephalocele and from other tumor lesions of the anterior fontanel.

[Depressed skull fracture in the newborn infant. To operate or not?]. / Fractura con depresión craneal en el recién nacido. Operar o no operar?

In recent literature the question of the convenience of neurosurgical treatment of cranial depressed fracture of the newborn has been a subject of discussion. The authors review their experience with 4 cases of this condition, that stress the necessity of the operation. Most reported series have dealt with the short-term results of the different ways of treatment. In this article the outcome is evaluated at least 10 years after surgery.
