Computed Tomography in Primary Malignant Lymphoma of the Brain

Abstract A new system has been developed for stereotactically delivering prescribed high doses of radiation to precisely located volumes of approximately 0.6 to 10.0 ml within the brain. A Brown-Roberts-Wells stereotactic apparatus and a 6-MeV linear accelerator equipped with a special collimator (12.5 to 30 mm in diameter) have been adapted. The 20-mm collimator allows treatment of a nearly spherical volume of 2.1 ml. Outside the treatment field, the dosage declines to 80% of the dose prescribed for the periphery of the lesion over a distance of 1.8 mm and to 50% over the next 3.4 mm. Localization can be accomplished via computed tomography or cerebral angiography. Treatment is accomplished with an arcing beam of photon radiation with the turntable (couch) in each of four positions. The entire system has been extensively tested for accuracy in alignment and distribution of radiation. Errors have been measured for the alignment of the apparatus and for the process of localization. Safety of operation was emphasized throughout the design and testing phase.

Angiogenesis is a critical compensation route, which has been demonstrated in the brain following ischemic stroke; however, few studies have investigated angiogenesis in chronic intracranial atherosclerosis disease (ICAD). We used 68Ga-NOTA-PRGD2 positron emission tomography/computed tomography based imaging to detect angiogenesis in chronic ICAD and to explore the factors that may have affected it. A total of 21 participants with unilateral severe chronic ICAD were included in the study. Of the 21 participants, 19 were men; the mean (SD) age was 52 (15) years. In 18 participants, we observed elevated 68Ga-NOTA-PRGD2 uptake in the peri-infarct, subcortical, and periventricular regions of the lesioned side, with a higher 68Ga-NOTA-PRGD2 SUVmax compared to that in the contralateral hemisphere (0.15 vs. 0.06, p=0.001). The 18F-FDG PET SUVmax was significantly lower on the lesioned side (11.28 vs. 13.92, p=0.001). Subgroup analyses revealed that the recent group (<6 months) had a higher lesion-to-contralateral region ratio SUVmax than the remote group (>6 months) (6.73 vs. 2.36, p<0.05). Our results provide molecular imaging evidence of angiogenesis in patients with severe chronic ICAD. Furthermore, the extent of angiogenesis in chronic ICAD may be affected by the post-qualified event time interval, and not by infarction itself or the severity of the arterial lesion.

Chief Complaints

Here, we report a case of prostatic abscess probably due to malignant lymphoma of the prostate. An 82-year-old man was referred to our hospital with chief complaints of urinary frequency and discomfort on urination. Antibiotics were prescribed, but the symptoms remained and intermittent fever appeared. The patient was diagnosed with prostatic abscess by computed tomography (CT). Digital rectal examination (DRE) revealed soft prostate, and thick pus was milked out from the extrameatus by prostatic massage. For drainage, we performed transurethral resection of the prostate (TURP). Drainage by TURP was successful as CT clearly showed reduction of prostatic abscess after the operation. Nevertheless, intermittent fever did not improve and the patient’s general condition deteriorated. The day before the patient died, histopathological analysis showed prostatic abscess probably due to malignant lymphoma of the prostate and incidental adenocarcinoma. This is the first report of prostatic abscess with malignant lymphoma involving the prostate.
