Paired Primary and Recurrent Rhabdoid Meningiomas: Cytogenetic Alterations, Gene Expression Profile and Patient Outcome.

Rhabdoid meningiomas (RM) are a rare meningioma subtype with a heterogeneous clinical course which is more frequently associated with recurrence, even among tumors undergoing-complete surgical removal. Here, we retrospectively analyzed the clinical-histopathological and cytogenetic features of 29 tumors, from patients with recurrent (seven primary and 14 recurrent tumors) vs. non-recurrent RM ( = 8).

[Radiopathologic update on dementias: postmortem magnetic resonance.].

Neurodegenerative diseases that course with dementia represent a public health problem that is growing in importance, mostly due to the aging of the population. Imaging techniques provide essential diagnostic and prognostic information. Some classifications of these diseases have recently been modified through the incorporation of histological, immunohistochemical, and genetic criteria.
