NO
In place of a histological diagnosis, the diagnostic adequacy of the combined use of 18F-FDG PET and corticosteroid administration for PCNSL located in a deep-seated brain structure is reported.

Male and Female
(1) there was no evidence of systemic malignancy
(2) the tumor was located in the deep site of brain, such as in the hypothalamus, brainstem including cerebral peduncle, and cerebellar peduncle, or periventricular infiltration
(3) the tumor had a high FDG uptake on PET, which is defined as when the FDG uptake of lesion is relatively higher than the that of adjacent and contralateral gray matter based on the visual inspection
(4) patients were radiological responders to corticosteroid administration
any cases which were not matched every inclusion criteria

Combining 18F-FDG PET and corticosteroids administration is an important alternative method that may lead to the diagnosis of deep-seated PCNSLs in cases with intractable histopathological confirmations.

Ten patients (four males and six females) matched these criteria. On pretreatment 18F-FDG PET, mean SUVmax in the tumor was 24.8 (8.75 - 60.75), and mean T/N ratio was 3.24 (2.17 - 5.12). The extent of tumor volume reduction was shown to be 21% to 68% one week after diagnostic therapy by corticosteroids. Nine patients achieved complete response and one patient achieved partial response on MRI after standard treatment for PCNSL with high-dose methotrexate and/or whole-brain irradiation.
