Summary

Primary brain lymphoma presents with characteristic imaging patterns on head computed tomography (CT) scans. Early consideration of lymphoma is crucial for appropriate management, potentially favoring biopsy and radiotherapy over surgery.

Area of Science:

  • Neurology
  • Radiology
  • Oncology

Background:

  • Primary brain lymphoma is a rare central nervous system malignancy.
  • Accurate and timely diagnosis is essential for effective treatment.
  • Computed tomography (CT) is a key imaging modality in evaluating brain lesions.

Purpose of the Study:

  • To analyze the computed tomographic (CT) features of primary brain lymphoma.
  • To assess the diagnostic utility of CT in identifying these lesions.
  • To evaluate treatment response and outcomes on follow-up CT.

Main Methods:

  • Retrospective review of head computed tomographic (CT) examinations.
  • Analysis of 14 patients diagnosed with primary brain lymphoma.
  • Assessment of lesion characteristics, location, and enhancement patterns.

Main Results:

  • Presenting lesions were predominantly single (62%) and iso- or hyperdense with homogeneous enhancement.
  • Common locations included deep hemispheric regions, corpus callosum, and posterior fossa.
  • Radiologists initially considered lymphoma in only 3 out of 14 patients.

Conclusions:

  • Primary brain lymphoma exhibits distinct CT imaging patterns.
  • Radiologists should consider lymphoma in the differential diagnosis of brain lesions with these features.
  • Needle biopsy and radiotherapy may be preferred treatment options over surgical resection.
