Carotid plaque is an aggregate marker of exposure to vascular risk factors, which are linked to structural brain changes. We investigated prestroke global and regional changes in brain volume in a carotid plaque population of cognitively healthy individuals and the association between carotid plaque characteristics and these changes. A total of 76 participants were divided into healthy control (HC, n = 28), vulnerable plaque (n = 27) and stable plaque groups (n = 21). ⋯ The gray-scale median (GSM) of the plaque and the total plaque risk score (TPRS) were correlated with the volume of the right middle occipital gyrus (r=-0.478, P = .001; r = 0.541, P = .001) and bilateral lingual gyrus (r = -0.419, P = .003; r = 0.288, P = .04). Carotid plaque is related to the volume of the brain parenchyma and right thalamus. The rGMVs of the right middle occipital gyrus and bilateral lingual gyrus differed between the vulnerable plaque and stable plaque groups, and the characteristics of carotid plaques may serve as indexes that reflect these changes.

Autoimmune hepatitis (AIH) is characterised by interface hepatitis. However, some acute cases exhibit atypical centrilobular necrosis with mild portal inflammation. Detailed histological and ultrastructural analyses of acute AIH are limited. ⋯ An important marker of acute AIH may be the presence of activated DCs in the hepatic sinusoids and central vein.

Neuroblastoma is the most common extracranial malignant solid tumor that occurs during childhood. It arises from primitive cells and is found in the adrenal medulla and sympathetic ganglia of the sympathetic nervous system. Huge neuroblastoma in the retroperitoneum, especially adult involvement is extremely rare. ⋯ Besides surgical resection, the treatment also included chemotherapy and radiotherapy. However, the optimal treatment remains controversial. Therefore, we should exert all our energies on the exploration of etiology and targeted drugs for this disease.

Laparoscopic port site metastases are a rare but clinically important cause of biochemically recurrent prostate adenocarcinoma. C-11 choline, among other prostate-specific positron emission tomography (PET) radiotracers, has improved radiologist confidence in these otherwise difficult-to-detect sites of recurrence. ⋯ Port site metastases in prostate adenocarcinoma are rare; however, those who treat prostate cancer patients should be aware of this phenomenon as the number of minimally invasive oncologic procedures increase. C-11 choline PET, among other prostate-specific PET probes, has become an important tool in evaluating patients with biochemically recurrent prostate adenocarcinoma, identifying site-specific metastases in a majority of patients.

Case Reports
Compressive radial neuropathy by a synovial cyst during pregnancy: A clinical case report.
Compressive radial neuropathy by a synovial cyst in the radial tunnel during pregnancy is a rare occurrence. The management of radial nerve compression caused by a synovial cyst in a pregnant patient is a surgical dilemma owing to the fetal and maternal risks of treatment. ⋯ symptoms from nerve compression were improved after surgical treatment LESSONS:: This report illustrates the case of a pregnant woman presenting a compressive neuropathy by an enlarged cyst possibly due to the unbalance of growth factors during pregnancy. With proper diagnosis and timely surgical intervention, such patients can achieve good neurologic recovery without maternal or fetal complications.
