| Dural, leptomeningeal, or ependymal enhancement are typical findings, none of which were present in this patient. |
|
| Salient autopsy findings included metastatic adenocarcinoma of peripancreatic lymph nodes and diffuse leptomeningeal carcinomatosis. |
|
| This is one of a handful of reported cases of a clinically undiagnosed gallbladder carcinoma presenting as leptomeningeal carcinomatosis. |
|
| Gadolinium enhancement is useful for detecting dural or leptomeningeal involvement at the skull base. |
|
| Tumor infiltration of leptomeningeal veins, cranial nerves, and spinal roots was also noted. |
|
| Melanin pigment, associated with melanocytes, is more typically leptomeningeal based, particularly in the ventral medulla and cervical spinal cord regions. |
|
| Ten cases demonstrated durai metastases, and 3 cases showed focal leptomeningeal involvement. cases of diffuse leptomeningeal carcinomatosis were excluded. |
|
| Significant leptomeningeal thickening with contrast enhancement were detected on T1-weighted images. |
|
| A 31-year-old male patient with Hodgkin's lymphoma and leptomeningeal involvement presented to at Hematology Departments of Ataturk University. |
|
| Valerie has been diagnosed with leptomeningeal carcinomatosis, which is very rare and usually a secondary or metastatic cancer. |
|
| Abnormal leptomeningeal enhancement within the right central sulcus and several adjacent sulci are seen on FLAIR images with contrast. |
|
| The leptomeninges and brain were hyperemic in all cases, four brains demonstrated diffuse leptomeningeal hemorrhages, and five had intracerebral hemorrhages. |
|
| Little George McIntosh suffers from a disseminated olligodendrial leptomeningeal tumour which, until now, has only been found in adults and never a child. |
|
| Dominic, of Low Fell in Gateshead, is one of only a handful of children in the world diagnosed with disseminated leptomeningeal glioneuronal tumour. |
|
| Aquaporin 4 was present in high amounts in astrocytes and ependymocytes and in low amounts in the choroidal plexus epithelia and leptomeningeal cells. |
|
| Follow-up tests revealed Harper had leptomeningeal carcinomatosis, a rare type of cancer that occurs in the meninges, thin membranes, that surrounds the brain and spinal cord. |
|
| Leptomeningeal carcinomatosis, the most frequent form of brain metastasis in prostate cancer, has a grim prognosis. |
