CT of the lungs or abdomen can also be diagnostic for infection, which is particularly relevant to immunocompromised patients.
(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) Marked decrease in the size of the mass in the tentorium and falx after radiation therapy and fludarabine treatment.Source: Kim HD. et al, Department of Internal Medicine, Yeoungnam University College of Medicine, Daegu, Korea.
Response to mTOR-inhibitor treatment in Waldenstrom's macroglobulinemia and lung toxicity.Baseline contrast-enhanced coronal CT images in 59-year-old woman show retroperitoneal lymphadenopathy (black arrows) and mild splenomegaly (A). Five months after start of treatment, coronal contrast-enhanced CT shows decreased adenopathy and splenomegaly (B). At baseline, clear lung bases were present (C). On five month follow-up CT (D), new ground-glass and reticular opacities developed in lung bases (white arrows), in keeping with mTOR-associated pneumonitis. Patient was asymptomatic. mTOR = mammalian target of rapamycin.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
