We report what is, to our knowledge, a unique case of a calcified extra-axial cerebellopontine angle (CPA) cavernoma involving the lower CNs.

CLINICAL

PRESENTATION: Saracatinib cost A 48-year-old man was admitted to our department with a 5-month history of gait instability and loss in tone of voice, A clinical examination documented gait disturbances and hoarseness but was otherwise unremarkable. Neuroradiological studies revealed a calcified mass in the lower third of the CPA cistern that was angiographically occult. it was associated with 3 additional lesions with a radiological appearance suggestive of multiple cavernomas.

INTERVENTION: The patient underwent a retrosigmoid approach, and the calcified mass, tightly adherent to the lower CNs, was gently removed. The histopathological examination was consistent with a cavernoma. Adriamycin in vivo The postoperative course was characterized by a further lowering in the patient’s tone of voice. At the 3-month follow-up examination, the patient showed significant improvement.

CONCLUSION: CPA cavernomas are an extremely rare entity. Symptoms are generally related to CN compression, and subarachnoid hemorrhage is a very rare occurrence. The clinical and radiological appearance may mimic that of other CPA tumors (meningiomas, schwannomas). In spite of the benign nature and the very low risk of hemorrhage, we believe, with support from the literature, that surgical treatment is mandatory to prevent significant

neurological deficits owing to the chronic CN compression.”
“PVS-RIPO is it recombinant oncolytic poliovirus

designed for clinical application to target CD155 expressing malignant gliomas and other Clomifene malignant diseases. PVS-RIPO does not replicate in healthy neurons and is therefore non-pathogenic in rodent and non-human primate models of poliomyelitis. A tetrazolium salt dye-based cellular assay was developed and qualified to define the cytotoxicity of virus preparations on susceptible cells and to explore the target cell specificity of PVS-RIPO. In this assay, PVS-RIPO inhibited proliferation of U87-MG astrocytoma cells in a dose-dependent manner. However, HEK293 cells were much less susceptible to cell killing by PVS-RIPO. In contrast, the Sabin type 1 live attenuated poliovirus vaccine strain (PV(1)S) was cytotoxic to both HEK293 and U87-MG cells. The correlation between expression of CD155 and cytotoxicity was also explored using six different cell lines. There was little or no expression of CD155 and PVS-RIPO-induced cytotoxicity in Jurkat and Daudi cells. HEK293 was the only cell line tested that showed CD155 expression and resistance to PVS-RIPO cytotoxicity. The results indicate that differential cytotoxicity measured by the colorimetric assay can be used to evaluate the cytotoxicity and cell-type specificity of recombinant strains of poliovirus and to demonstrate lot to lot consistency during the manufacture of viruses intended for clinical use.
