Polymeric micelle of the A₃B-type lactosome comprising (poly(sarcosine))₃-b-poly(l-lactic acid) was labeled with 111In. The 111In-labeled A₃B-type lactosome was administered to the model mice bearing meningeal dissemination and bone metastasis at mandible. With single-photon emission computed tomography (SPECT) imaging, the meningeal dissemination was identified successfully by 111In-labeled A₃...

In this report, the patient was pre-diagnosed as meningioma before surgery, which turned out to be meningeal melanocytoma. Hence, we will discuss the interpretation of imaging and neurological statuses that may help avoid this problem. A 45-year-old man had increasing pain around the neck 14 months prior to admission. His cervical spine MR imaging revealed a space-occupying, contrast-enhancing ...

Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the ...

Meningeal melanocytoma is a rare pigmented tumor of the leptomeningeal melanocytes. This rare entity results in diagnostic difficulty in imaging unless clinical and histopathology correlation is performed. In this case report, we describe a case of meningeal melanocytoma of the cervical region presenting with superficial siderosis. Extensive neuroradiological examination is necessary to locate ...

1. an instance of an abnormal artery arising from the middle meningeal is described. 2. the embryologic and possible clinical significances of this anomaly are discussed.

Multiple cranial nerve palsies often reveal a meningeal process that may be infectious, inflammatory, or neoplastic in origin. Even when there is a known history of malignancy, the rarity with which a given primary cancer causes meningeal carcinomatosis can influence diagnostic decision making and lead to delays in diagnosis. We present a unique case of a patient with deafness and blindness sec...

MR showed an enhancing mass in the pineal region and hydrocephalus and leptomeningeal enhancement, thought to indicate pinealoblastoma with leptomeningeal spread. During resection there was no evidence of spread, and repeat MR showed no residual tumor or meningeal enhancement, so the patient was not treated for metastasis. Because there were no signs of leptomeningeal tumor 4 months after surge...

Two cases of meningeal sarcoidosis with unusual and misleading presentations are reported. In the first case, CT scan, angiographic, and MRI findings were indistinguishable from those of meningioma. CSF pleiocytosis may help in diagnosing sarcoid pseudo-meningioma. The second patient had transient focal deficits and pachymeningitis of the convexity. The transient deficits were probably of epile...

Abstract Background Corona virus disease has been associated with a wide variety of fungal and bacterial co-infections. These secondary infections could be due to the irrational use antibiotics, immunosuppressive therapy, pre-existing co morbidities, immune modulator effects virus. But here, we report very rare occurring rhino-orbito-cerebral invasive sinusitis in malnourished child no other mo...

The tumours to be considered here are those arising primarily in the meninges, or gaining access to them as secondary growths. It will be necessary to consider not only the dura and leptomeninges that invest the brain and spinal cord, but also their extensions into the brain as the tela choroidea and stroma of the choroid plexuses, and the sheaths of the perforating blood-vessels that form the ...
