Abstract

Nonneoplastic mass lesions of the central nervous system mimic tumors clinically and radiographically. Their etiology is diverse. Although nonneoplastic mass lesions may also require surgical resection, recognition of such lesions and an accurate diagnosis utilizing only imaging modalities may, at times, spare the patient from invasive procedures. Failing to differentiate between the two may delay treatment in malignant tumors or result in unnecessary treatment in nonneoplastic lesions. When surgery is required, utilization of imaging modalities to accurately predict a diagnosis may help the neurosurgeon plan the intervention accordingly. This chapter provides an overview of nonneoplastic mass lesions and their characteristics on neuroimaging studies.

Abstract

Serine/threonine protein phosphatase 2A (PP2A) may play a role in leukaemic cell differentiation of the HL-60 myeloid leukaemic cell-line after methylprednisolone induction. We have investigated the specific enzyme activity and expression of catalytic and regulatory subunits of PP2A. The resulting specific enzyme activity and immunoblots showed an increase in enzyme activity and the expression of regulatory subunits after methylprednisolone treatment. There was no change in the expression of PP2A catalytic subunits. It is suggested that the effect of methylprednisolone on leukaemic differentiation may be the result of PP2A upregulation.
