Introduction:
Trigeminal neuralgia is a disorder characterized by unilateral electric

shock-like pain, distributed in one or more trigeminal nerve branches and triggered by
usually innocuous stimuli. Among the few case reports and literature reviews on familial
trigeminal neuralgia (FTN), the results of several suggest the involvement of genes associated with biochemical alterations or atherosclerotic vascular malformations.
Background: We present four cases of FTN within two families (family A: two brothers;
family B: two sisters). All patients were submitted to surgical treatment by the same
surgeon.
Discussion:
Cases 1 and 2 (family A) exhibited FTN with an uncommon autosomal
recessive pattern and clinical features consistent with previous literature reviews and
case reports. However, in cases 3 and 4 (family B), we found FTN with a dominant autosomal pattern and an unusual physiopathology characterized by arachnoid adhesions.
Conclusion:
We conclude, in this case report, that there are several inheritance patterns
as well as physiopathology that may be involved in FTN, and that both patterns described
in our reported cases were successfully managed with surgery.

Las hemorragias cerebrales, también conocidas como derrames cerebrales hemorrágicos, son emergencias médicas que requieren atención inmediata. Ocurren cuando un vaso sanguíneo en el cerebro se rompe, causando sangrado dentro o alrededor del tejido cerebral. Comprender los diferentes tipos de hemorragias cerebrales es crucial para su diagnóstico y tratamiento adecuados.

Como neurocirujano especializado en cirugía de base de cráneo, he tratado numerosos casos de tumores pituitarios a lo largo de mi carrera. Estos tumores, aunque generalmente benignos, pueden tener un impacto significativo en la salud y la calidad de vida de los pacientes. En este artículo, exploraremos los síntomas principales y las opciones de tratamiento más actuales para los tumores de la glándula pituitaria.
