چکیده

Richter transformation is defined as a diffuse large cell lymphoma, occurring by transformation of chronic lymphocytic leukemia (CLL). We present a 64-year-old man with a history of CLL and a left parieto-occipital transtentorial extra-axial mass. The patient underwent CT and MR imaging, demonstrating a large dural-based mass with extracranial extension, which occluded the left transverse sinus. Biopsy of the mass proved a pathologic diagnosis of diffuse large cell non-Hodgkin lymphoma, consistent with Richter transformation of CLL.

Detection of Hodgkin Transformation in a Case of Chronic Lymphocytic Leukemia by PET/CT

Richter's transformation (RT) represents the development of high grade lymphoma, most commonly diffuse large B-cell lymphoma, in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL). CLL/SLL may convert also to Hodgkin's lymphoma, the so-called Hodgkin's variant of Richter transformation. Histopathological proof is needed to confirm a definitive diagnosis. Patients...

Hodgkin lymphoma transformation of chronic lymphocytic leukemia/small lymphocytic lymphoma.

Transformation to a large cell lymphoma may occur during the course of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in approximately 5% of the cases. This is known as Richter's transformation. A much less frequent transformation to Hodgkin lymphoma may occur. We report a case of CLL/SLL in which a transformation to Hodgkin lymphoma occurred, and we review previously publish...

Intravascular large B‐cell lymphoma presenting as Richter's syndrome with cerebral involvement in a patient with chronic lymphocytic leukemia

Intravascular large B-cell lymphoma (IVLBCL) is an aggressive non-Hodgkin's lymphoma which can present with B symptoms, rash, and neurological deterioration. Up to 10% of cases of IVLBCL are associated with other hematological neoplasms, including this extremely rare presentation of IVLBCL as Richter's transformation in chronic lymphocytic leukemia.
