[Dural metastatic infiltration in prostate cancer--case report]. / Przerzuty raka gruczolu krokowego do opon mózgowych--opis przypadku.

Metastatic changes secondary to prostate cancer usually occur in bones, less commonly in pelvic lymph nodes, liver, lungs, urinary balder and brain. Less common localization includes skin, testis and other structures. The current paper reports a rare case of metastatic infiltration of the dura mater in patient with prostate cancer (Gleason 8 (4+4)) with disseminated bone metastasis. Magnetic resonance imaging revealed an advance infiltration of dura mater of anterior and posterior cranial fossa without any neoplasmatic-related changes in brain. Along optic nerves it penetrated to the optic canal and right orbit.

Solid-pseudopapillary neoplasm of the pancreas - comparisons between magnetic resonance and histological findings.

Solid-pseudopapillary neoplasm is a rare pancreatic tumor typically observed in young adults. A new case of the tumor was diagnosed in a 22-year-old woman. An abnormal mass connected with the pancreatic body was found on ultrasound and computed tomography. Magnetic resonance revealed weak homogeneous contrast enhancement and a low ADC value (0.824 mm/s2; b1000). Primary radiological diagnosis suggested a solid pancreatic neoplasm, which was confirmed during histopathological assessment after resection of the pancreatic body with preservation of the spleen and normal drainage through the main pancreatic duct. Histological appearance of the solid-pseudopapillary neoplasm corresponded with its radiological morphology.
