tuberculosıs: an old but resurgent problem. Axial contrast-enhanced CT (a) and axial T2 weighted MR (b) images of a 66-year-old female demonstrate multiple foci (arrowheads) in the spleen. Note small hypodense areas with peripheral enhancement in foci (a). Splenic TB

tuberculosıs: an old but resurgent problem. A coronal contrast-enhanced CT image of a 43-year-old male shows multiple hypodense lesions (arrows) in the liver and spleen. Hepatic and splenic TB

Extrapulmonary

tuberculosıs: an old but resurgent problem. Abdominal CT scan and MR images of the same patient (in Fig. 27). Contrast-enhanced CT (a) and T1 weighted contrast-enhanced MR images (b) show a small abscess formation with rim-like enhancement in the anterior subcapsular region of the liver. Diffusion-weighted images (DWI) (c) and apparent diffusion coefficient (ADC) map (d) reveal diffusion restriction consistent with an abscess

A Case of

Mass-Forming Splenic Tuberculosis: MRI Findings with Emphasis of Diffusion-Weighted Imaging Characteristics: Abdominal MRI of a 45 yr-old female shows an isolated splenic lesion. (A) Irregular conglomerated splenic lesion shows internal hyperintensity with peripheral hypointensity (arrowheads) on fat-suppressed T2-weighted image. (B) Contrast enhancement of peripheral rim (arrowheads) with non-enhancing central portion is noted on the gadolinium-enhanced T1-weighted image. (C) Diffusion-weighted MRI (b=800 sec/mm2) shows a prominent internal hyperintensity surrounded by rather hypointense rind. (D) Profound diffusion restriction is demonstrated in the internal component (arrowhead) with low ADC value (0.580 × 10-3 mm2/sec). (E) Gross specimen shows an irregularly marginated yellowish mass (arrowheads) filled with cheesy necrotic material (asterisks). (F) Corresponding outer granulomatous component (white asterisks) with internal caseous necrosis (black asterisk) is confirmed on high power field microscopy with hematoxylin and eosin stain.
