Aneurisma gigante no traumático de la arteria meníngea media. A propósito de un caso y revisión de la literatura / Non traumatic giant aneurysm of middle meningeal artery. Case report and review of the literature

Se presenta un caso de aneurisma gigante no traumático de la arteria meníngea media en un paciente de 59años con antecedentes de trasplante hepático, cirrosis hepática y hepatocarcinoma, enfermedad renal crónica, HTA y bronquitis crónica que ingresó por presentar crisis tónico-clónica. La TC y la RM mostraron una lesión sugestiva de metástasis sin descartar un tumor de tipo glial. Fue intervenido mediante una craneotomía FT izquierda. Durante la cirugía se produjo una hemorragia arterial. La muestra histológica orientó hacia un origen aneurismático que se confirmó con ARM y angiografía. Una segunda intervención permitió la extirpación de un aneurisma gigante de la arteria meníngea media parcialmente trombosado. Los aneurismas de la arteria meníngea media son raros y en general presentan un antecedente traumático. No se ha encontrado en la literatura médica ningún caso de aneurisma gigante

A case of a non-traumatic giant aneurysm of the middle meningeal artery is presented in a 59-year-old patient with a history of liver transplantation, liver cirrhosis and hepatocarcinoma, chronic renal disease, hypertension and chronic bronchitis who presented with tonic-clonic seizures. CT and MRI showed a lesion suggestive of metastasis without ruling out a glial type tumor. He was operated through a left FT craniotomy. During the surgery there was an arterial hemorrhage. The histological sample oriented toward an aneurysmal origin that was confirmed with ARM and angiography. A second intervention allowed the removal of a giant middle meningeal aneurysm partially thrombosed. Aneurysms of the middle meningeal artery are rare and generally present a traumatic history. No case of giant aneurysm has been found in the medical literature

Pathological findings in the complete trisomy 9 syndrome: three case reports and review of the literature.

The term "complete trisomy 9" is used to indicate trisomy of the entire chromosome 9 without evidence of mosaicisms. It is a relatively rare chromosomal abnormality because the vast majority of affected pregnancies result in 1st trimester spontaneous abortions. The purpose of this paper is to delineate the complete trisomy 9 syndrome, based on autopsy findings. We performed an exhaustive review of the literature of complete forms of this trisomy with autopsy examination and added 3 new cases from our center with new findings not previously described.
