Περίληψη:
The imaging studies of seven patients (two of whom had acquired
immunodeficiency syndrome) with histologically proven primary lymphoma
of the central nervous system (PCNSL) were reviewed. Computed tomography
(CT) and magnetic resonance imaging (MRI) scans were taken prior to and
following radiotherapy. After radiotherapy, except in one case, all
tumors rapidly decreased in size either partially or completely. The
imaging features on MRI scans are not pathognomonic since intracerebral
infections or gliomatosis cerebri may give similar findings. However, on
T2-weighted images, homogeneous, slightly high-signal to isointense
masses deep within the brain and in close proximity to the corpus
callosum may give characteristic appearances. MRI findings assist in the
differential diagnosis between PCNSL and toxoplasmosis, metastatic
disease, gliomas and infarcts, especially if the tumor is situated in
the brain stem and the posterior fossa. It is also useful in the
follow-up of patients after radiotherapy in order to make management
decisions related to adjuvant chemotherapy administration.
