AIDS-related lymphomas (ARL) present atypically in the chest, often as nodules or masses. Chest CT scans are crucial for diagnosing these ARL manifestations in HIV-positive patients.

Area of Science:

  • Oncology
  • Radiology
  • Infectious Diseases

Background:

  • The incidence of neoplasms secondary to immunodepression is increasing.
  • Improved control of opportunistic infections parallels the rise in neoplasms.
  • AIDS-related lymphomas (ARL) are a significant concern in immunocompromised patients.

Purpose of the Study:

  • To describe the prevalence and radiological features of thoracic manifestations of ARL.
  • To highlight the diagnostic utility of CT in identifying ARL in HIV-positive patients.
  • To compare the incidence and presentation of thoracic ARL with existing literature.

Main Methods:

  • Observation of 122 patients with AIDS and 20 with ARL over 4 years.
  • Analysis of radiological features, including conventional X-rays and CT scans.

  • Correlation of imaging findings with pathological diagnoses.

    • Main Results:

    • Five out of 20 ARL cases (25%) presented with thoracic lesions, with 4 having chest onset.
    • Radiological features were atypical, predominantly nodules or rapidly growing peripheral masses (60%).
    • CT scans revealed bilateral lesions and provided detailed morphologic and densitometric information, aiding diagnosis and biopsy site selection.

    Conclusions:

    • Thoracic ARL manifestations are more common than previously reported.
    • Atypical radiological patterns, particularly nodules and masses, are highly suggestive of ARL in HIV-positive individuals.
    • CT is an invaluable tool for diagnosing pulmonary lymphoma and guiding biopsy in this population.
