Occurrence of Glioblastoma Five Years After Resection of Atypical Meningioma at the Same Anatomic Site: A Case Report.

Atypical meningioma is a type of intermediate-grade meningioma (grade 2) according to the WHO classification. The occurrence of glioblastomas at the same site of resection of a meningioma is extremely rare and the causes of this type of mutations should be investigated. We present a case of a 54-year-old patient who five years after resection of a left parietooccipital atypical meningioma presented with a glioblastoma at the same site.

Lumbar osteomyelitis with psoas muscle abscess in a patient with prostate cancer.

osteomyelitis is a rare clinical entity more commonly described in grounds of sickle cell disease however some cases has been described in patients without this pathology but an immunocompromised state, which also predisposes to the development of a psoas abscess. We present the case of a 77-year-old man with persistent hip pain and recent diagnosis of prostate cancer who developed lumbar osteomyelitis and a secondary psoas abscess due contiguous spread. Treatment included a third-generation cephalosporine and fluoroquinolone without surgical drainage with a good prognosis overall.
