Background and Purpose: Computed tomography (CT) scan is difficult to detect early-onset acute intracerebral hemorrhage (ICH) rich in fresh blood correctly. We identified the presence of a perihematomal low-density lesion on CT imaging, which showed a high-intensity signal on T2-weighted imaging and an iso-intensity signal on fluid-attenuated inversion recovery imaging in magnetic resonance imaging (MRI) (Figure. A~C). It located inside of the hypo-intensity rim at the edge of hematoma on gradient recalled echo T2*-weighted imaging (Figure. D). We named it the “CT wall sign” and investigated the association with imaging findings in acute ICH. Methods: Patients with acute ICH within 24 hours from onset who underwent non-contrast head CT and MRI scan at the same time periods were included. The ICH volumes on CT and MRI (cm 3 ) were measured using a three-dimensional slicer and compared. Subjects were divided according to the presence or absence of the CT wall sign and compared the neuroradiological variables. Statistical analyses were performed to evaluate the association between the CT wall sign and other imaging findings. Results: A total of 146 patients were included and the CT wall sign was observed in 42 (29%) patients. The difference in the ICH volume between MRI and CT were significantly larger in the CT wall sign-positive group than in -negative group (6.0 cm 3 versus 0.40 cm 3 , P <0.001). The presence of CT wall sign was significantly associated with putamen hemorrhage ( P =0.049), large hematoma > 11.36 cm 3 ( P =0.005), and niveau formation in the hematoma ( P <0.001). Conclusions: The presence of the CT wall sign suggests that the volume of an acute ICH may be larger than it appears on CT imaging. Key words: Acute intracerebral hemorrhage, Computed tomography, Magnetic resonance imaging, Perihematomal low-density area.

Background Non-hypervascular pancreatic neuroendocrine tumors (PNETs) showed slight or iso-enhancement in contrast-enhanced computed tomography (CE-CT), which shared similar imaging findings with mass-forming pancreatitis (MFPs). Purpose To explore the value of CT imaging features in differentiating the two diseases. Material and Methods Fifty-one patients with histologically proved MFPs (n = 27) or non-hypervascular PNETs (n = 24) were included. Two radiologists reviewed CT imaging findings and clinical features. Logistic regression analysis was performed to identify relevant features in differentiating non-hypervascular PNETs and MFPs. Receiver operating characteristic (ROC) curve analysis was used to show the performance of the optimal parameters in differentiating non-hypervascular PNETs and MFPs. Results A well-defined margin was more common in non-hypervascular PNETs ( P < 0.05) than that in MFPs. MFPs often occurred in older people ( P < 0.01) and the head–neck of the pancreas compared with non-hypervascular PNETs ( P < 0.05). Metastases only presented in non-hypervascular PNETs ( P < 0.05). CT values at venous phase and delay phase of MFPs were higher ( P = 0.010 and P = 0.029) than those in non-hypervascular PNETs. Logistic analysis showed gender, tumor margin, CT values at venous phase, and tumor components were independent predictors in differentiating the two lesions. The area under the curve (AUC) was 0.938 with a sensitivity of 87.5% and specificity of 92.6% for combined predicators. Conclusion Gender, tumor margin, CT values at venous phase, and tumor components were useful predicators in differentiating non-hypervascular PNETs and MFPs.

Upper Abdomen

Adrenal pseudocysts are rare entities and occurred in the 5th and the 6th decades of life. They are discovered accidentally, while appearing with nonspecific clinical and imaging findings. We report a case of a 28-year-old woman presented in our Emergency Department complaining about upper abdomen pain. Computed tomography revealed a hypodense cystic lesion containing hyperdense material. The size of a mass was 11. 7 × 9.3 × 6.6 cm in diameter close to the pancreas, but the origin was from the left adrenal gland. The mass was excised with surgical laparotomy. Giant adrenal pseudocysts are rare entities. Final diagnosis usually confirmed with the pathology examination. Management of such adrenal lesions depends on the unique characteristics, the surgeon’s experience, and local resources.

Purpose. To characterize the computed tomography (CT) imaging findings in patients with pulmonary chondroma. Methods. We examined CT imaging findings of eight patients with histopathologically verified pulmonary chondroma. We assessed the location, size, shape, margins, amount of calcification, calcification pattern, and attenuation on precontrast and enhancement CT. Results. All patients exhibited solitary, mildly lobulated pulmonary masses, which were located in the right lung in four cases and the left lung in four cases. The mean lesion size was 3.7 cm (range 0.9–10.7 cm). All eight tumours had a well-defined margin. On plain CT images, seven of the cases (87.5%) showed a mass with varying degrees of calcification, which included strip-like punctate (n=5) and ring (n=2) patterns. One patient with a large lesion (10.7 cm) showed chest wall adhesion. On contrast-enhanced CT images, all lesions demonstrated slight inhomogeneous enhancement ≤14 HU. Conclusion. CT is the reference standard diagnostic technique for locating pulmonary chondroma. In most cases, CT findings show some characteristics that are important in the diagnosis, surgical planning, and follow-up of the tumour.
