Contribution of Computed Tomography in the Diagnosis of Multifocal Non-Hodgkin’s Lymphoma at the Mother-Child University Hospital the ‘’Luxembourg’’ About a Case

Lymphoma is a malignant proliferation of lymphoid tissue cells. We report a case of multi-focal lymphoma of lymph node, pharyngeal, cardiac and splenic sites. This was a 19-year-old patient received in February 2023, at the radiology and medical imaging department of the Mother and Child University Hospital Center ''Luxembourg'' as part of the CT exploration of a lateral mass. -left cervical. On admission, the clinical examination found a patient with an altered general condition, moderately colored conjunctiva, normal blood pressure and temperature. Examination of the lymph node areas revealed a left latero-cervical swelling, and fixed bilateral axillary swellings, of firm consistency and irregular contours. Palpation revealed hepatosplenomegaly. Cardiopulmonary auscultation was normal. A cervico-thoraco-abdominal CT scan revealed irregular thickening of the left lateral wall of the oropharynx, a hypodense tissue mass in the right cardiac chambers, heterogeneous splenomegaly, cervical, mediastinal, axillary and abdominal ADP. The histological examination carried out after lymph node biopsy revealed a histological appearance of small cell lymphoma. Conclusion: Lymphoma is a very common malignant tumor that can occur at any age. This tumor can affect all organs, however its cardiac location is rare. The positive diagnosis remains histological. Imaging plays an important role in the initial assessment, extension and surveillance.
