[Epidermoid cyst of the parapharyngeal space]. / Quiste epidermoide de espacio parafaríngeo.

Epidermal cysts of parapharyngeal location are very unusual tumors, with a benign character, though when they reach a great size, adjacent zones and vascular and nervous structures of great importance can be affected. We are going to describe the clinical aspects of this case, the instructions and the surgical approach used: the Fabre inferior and internal jaw approach of the lateropharingeal space and infrasphenotemporal fossa, which avoids the aesthetics and functional aftereffects of other more common approaches.

Quiste epidermoide de espacio parafaríngeo / Epidermal cyst of the parapharyngeal space

Los quistes epidermoides de localización parafaríngea son tumores muy infrecuentes, de carácter benigno, aunque cuando alcanzan un gran tamaño, pueden afectar a zonas vecinas y comprometer a estructuras vasculares y nerviosas de gran importancia. Presentamos las características clínicas de un caso, así como las indicaciones y la técnica quirúrgica empleada: abordaje inferior y mandibular interno de Fabre de la región laterofaríngea y fosa infraesfenotemporal, que evita las secuelas estéticas y funcionales de otras vías más utilizadas (AU)

[Wallenberg syndrome as a sign of rhombencephalitis-meningitis due to Listeria monocytogenes]. / Síndrome de Wallenberg como manifestación de meningorrombencefalitis por Listeria monocytogenes.

We report a case of rhombencephalitis with meningitis in a 36-years-old previously healthy man; neurological signs and symptoms were initially consistent with a diagnosis of Wallenberg syndrome. Analysis of cerebrospinal fluid showed predominantly lymphocytic pleocytosis and elevated protein levels. A CT brain scan was normal. MRI of the brain showed a hypertensive type lesion in T2, in the right pontomedullary region that suggested inflammation. A blood culture grew Listeria monocytogenes. The patient improved and fully recovered with appropriate antibiotic treatment. Listeria monocytogenes is a recognized cause of acute brainstem meningoencephalitis. Differential diagnoses that must be considered are other forms of purulent meningitis, viral meningoencephalitis, granulomatosis infections of the central nervous system and, occasionally, stroke.
