Overview

Overview

In lymphoplasmacytic lymphoma, CT scan imaging of chest, abdomen, and pelvis may show evidences of lymphadenopathy and hepatomegaly. CT of the lungs or abdomen can also be diagnostic for infection, which is particularly relevant to immunocompromised patients.

Abdominal computed tomography (CT) showing significant hemoperitoneum, with extravasation of contrast into the right flank/paracolic gutter. Hepatomegaly and splenomegaly are clearly seen.

Transaxial slices representative of the isodose distribution of the 3D-CRT treatment plan delivered for the whole spleen. A, In the first stage, isodose curves were produced by 3 oblique isocentric photon fields of beam quality 10-MV; B, In the second stage, isodose curves were produced by 5 oblique isocentric photon fields of beam quality 10-MV.

Response to mTOR-inhibitor treatment in Waldenstrom’s macroglobulinemia and lung toxicity. Baseline contrast-enhanced coronal CT images in a 59-year-old woman show retroperitoneal lymphadenopathy (black arrows) and mild splenomegaly (A). Five months after the start of treatment, coronal contrast-enhanced CT shows decreased adenopathy and splenomegaly (B). At baseline, clear lung bases were present (C). On a five-month follow-up CT (D), new ground-glass and reticular opacities developed in lung bases (white arrows), in keeping with mTOR-associated pneumonitis. The patient was asymptomatic. mTOR = mammalian target of rapamycin.[https://openi.nlm.nih.gov/detailedresult.php?img=PMC5240491_kjr-18-28-g007&query=waldenstrom+macroglobulinaemia&it=xg&req=4&npos=36 Source: Krajewski KM. et al, Department of Imaging, Dana-Farber Cancer Institute, Boston, MA 02215, USA.; Department of Radiology, Brigham and Women’s Hospital, Boston, MA 02115, USA

(A) Contrast-enhanced axial and coronal T1-weighted images show a well-enhanced mass along the left tentorium and cavernous sinus (arrows). This mass also extends into the contralateral tentorium and falx (arrowheads). (B) A marked decrease in the size of the mass in the tentorium and falx after radiation therapy and fludarabine treatment.[https://openi.nlm.nih.gov/detailedresult.php?img=PMC2694623_jkms-22-1079-g001&query=waldenstrom+macroglobulinaemia&it=xg&req=4&npos=28 Source: Kim HD. et al, Department of Internal Medicine, Yeoungnam University College of Medicine, Daegu, Korea.
