“…8 As the onset is insidious in most patients (the typical pseudotumoral clinical course), many patients are considered as harboring a brain tumor, 2 intratumoral bleeding or necrosis, and cerebral abscess. 5,9 The content of the hematomas ranges from stale xanthochromic fluid to newly formed clots, which indicates the development of intracerebral hematomas in different phases. The mean course of this series was 7 months, but both acute or subacute onsets (varying from 1 wk to 3 mo) have also been reported.…”

Background: To introduce an alternative hypothesis of a probable mechanism of chronic expanding intracerebral hematoma (CEICH) based on "tree-ring" sign on magnetic resonance imaging (MRI) scan, which has been defined in our department for several years.Methods: Thirty-seven consecutive patients verified as CEICH were recruited in this series to screen patients with "tree-ring" sign on MRI scan. The history, clinical manifestations, and features of MRI scans of the patients were also documented and analyzed.Results: Only 13 of the 37 lesions were correctly diagnosed as CEICH based on MRI scan before surgery. All the 7 patients with "tree-ring" sign on MRI scan were correctly diagnosed preoperatively. Vascular anomaly was verified by both intraoperative findings and postoperative histologic examination in all the 7 cases with "tree-ring" sign. In addition, these vascular anomalies were situated more intrinsically than another 6 peripherally located ones. Conclusions:The "tree-ring" sign on MRI scan probably mirrors the intrinsically derived bleeding as an alternative attributable mechanism that accounts for the progressive expansion of CEICH in addition to the widely accepted hypothesis of capsule-originated bleeding.

“…These thrombusderived contents can provoke inflammation of the aorta and proliferation of the vessel. The vasa vasorum type II endoleak may reasonably be formed via the neovascularization of the thrombus within the lumen through inflammatory or organizational processes or through extravasation from fragile proliferating microvessels into the lumen, which may simulate the formation of a chronic expanding hematoma [5].…”

An 84-year-old man with an abdominal aortic aneurysm with a largest diameter of 50 mm was treated using endovascular aortic repair (EVAR) within the instructions for use. Computed tomography (CT) performed 3 years after the EVAR revealed significant sac expansion. The first (3 years after EVAR) and second (4 years after EVAR) transarterial embolizations demonstrated rare type II endoleaks from the vasa vasorum as multiple fluffy contrast blushes from the aortic tributaries. As sac expansion persisted at 5 years after the EVAR, translumbar direct puncture of the sac and embolization using a mixture of 25% n-butyl cyanoacrylate and lipiodol was performed. A follow-up CT 2 years after the last embolization showed sac stability without any complications.

“…Cysts can vary depending on different manifestations and different periods of bleeding, and can be of high or mixed density. On enhanced CT, granulation tissue with rich neovascularization can be observed as a ring enhancement pattern that is similar to that of brain abscesses [ 4 , 5 ]. Most lesions cause significant mass effect and cerebral edema around the lesion, which varies depending on the size and location of the lesion.…”

SummaryBackgroundChronic encapsulated intracerebral hematoma (CEICH) is a rare type of intracerebral hematoma that is often misdiagnosed.To explore the characteristics of CEICH on computerized tomography (CT) and magnetic resonance imaging (MRI).Material/MethodsClinical, CT, MRI, and susceptibility weighted imaging (SWI) data of 5 patients who were diagnosed with CEICH on surgery and pathology were retrospectively analyzed.ResultsCT showed quasi-circular or elliptical lesions with clear borders in all 5 cases and iso-density or low-density in the center of lesions that were surrounded by peripheral edema in 2 cases. CT showed mass effect in 5 patients. On contrast-enhanced CT, 2 cases exhibited mild ring enhancement, and 3 cases exhibited moderate ring enhancement. MRI showed cystic lesions with high uniform signal on T1-weighted images (T1WI) and T2-weighted images (T2WI), a lowsignal ring sign on the coated cystic lesions on T2WI, a lower signal ring sign on SWI, and ring enhancement after administration of contrast.ConclusionsCT imaging of CEICH did not reveal any typical characteristics in the studied patients. MRI showed an envelope with a “ring” and intra-capsular bleeding features. MRI is an effective imaging modality for the diagnosis of CEICH.
