Schistosoma mansoni is highly endemic in Tanzania and affects all age groups at different degrees. However, its control approach does not include adult individuals who are equally at risk and infected. To justify the inclusion of adult individuals in MDA programs in Tanzania, the present study focused on determining the prevalence of S. mansoni infection and its related morbidities among adult individuals. This was a cross sectional study conducted among 412 adult individuals aged 18–89 years living in selected villages of Rorya and Butiama districts located along the shoreline of the Lake Victoria. A pretested questionnaire was used to collect socio-demographic and socio-economic information of participants. Ultrasonographic examinations were conducted for all study participants using the Niamey protocol. A single stool sample was obtained from all study participants and examined for S. mansoni using the Kato-Katz technique. The study revealed a high prevalence of S. mansoni (56.3%), and the majority of infected individuals had a light intensity of infection. Ultrasonographic findings revealed that 22.4% of adult individuals had periportal fibrosis (PPF) (grade C–F), with 18.4% having grade C and D and 4% having grade E and F. Males had the highest prevalence of PPF (31.7% vs 10.8%, P < 0.001). Organomegaly was common with 28.5% and 29.6% having splenomegaly and hepatomegaly, respectively. S. mansoni infection and its related morbidities included PPF, hepatomegaly, and splenomegaly were common among adult individuals. To reduce the level of transmission of S. mansoni infection, planned mass drug administration campaigns should include adult individuals living in these villages.

We report a case of a fetus with an ultrasonography diagnosis of a neuroblastoma during a routine third trimester fetal scan, which presented as a hyperechogenic nodule located above the right kidney. No other abnormalities were found in the ultrasonography scan; however, the follow-up ultrasonography during the 36th week of gestation revealed that the lesion had doubled in size. At the same time, magnetic resonance imaging demonstrated a round mass in the topography of the right adrenal gland with a low signal on T1-weighted images and slightly high signal on T2-weighted images, causing a slight inferior displacement of the kidney. The liver had enlarged and had heterogeneous signal intensity, predominantly hypointense on T2-weighted sequences. Based on these findings, a diagnosis of congenital adrenal neuroblastoma with liver metastases was suggested. A newborn male was delivered by cesarean section 2 weeks later. The physical examination of the neonate revealed abdominal distention and hepatomegaly. The infant had a clinical follow-up in which no surgical or medical intervention was required. At 5 months of age, the infant was asymptomatic with a normal physical examination.

BACKGROUND: Hepatic hemagioendothelioma in neonatal period was rarely seen, so standard treatment does not established yet.METHODS: A retrospective analysis of patients with neonatal hepatic hemangioendothelioma at Ajou University Hospital between 2001 and 2016 was performed.RESULTS: Six patients with hepatic hemangioendothelioma in neonatal period were founded. Mean age at diagnosis was 6.1 days (range, 1-26 days). Three patients have no symptoms; diagnostic approach was prenatal ultrasonography in 2 patients, and incidental abnormal ultrasonographic findings in 1 patient, but the other 3 patients have hepatomegaly and/or congestive heart failure. Three patients were observed without treatment and the other 3 patients received medical and/or surgical treatment. Three patients of those who did not receive treatment became spontaneous regression. Of the other 3 patients, 1 patient achieved complete tumor disappearance after surgical resection, another 1 patient achieved to decrease tumor size with interferon-alpha treatment for 6 months and then had complete resolution of tumor after partial liver lobectomy, and other 1 patient who received hepatic artery embolization decreased in the size and number of lesions and then regressed gradually.CONCLUSION: Asymptomatic patients with neonatal hepatic hemangioendothelioma could have spontaneous remission, but patients with symptoms such as hepatomegaly with congestive heart failure or thrombocytopenia needed to be applied with medical and/or surgical treatment.

We herein report the case of a 14-year-old girl with Epstein-Barr virus (EBV) infectious mononucleosis who developed prolonged hepatitis and jaundice. At presentation, she had tender hepatomegaly with a markedly deranged liver function test. Abdominal ultrasonography showed hepatomegaly and a thickened gallbladder wall. During the subsequent 11 weeks, her transaminases showed two further peaks, which corresponded with clinical deterioration. Her highest alanine transaminase level was 1,795 µ/L and total bilirubin level was 154 µmol/L. She recovered fully with conservative management. EBV-related liver involvement is typically mild and self-limiting. We believe that tender hepatomegaly and gallbladder thickening may be important predictors of significant liver involvement. Although multiple transaminase peaks may occur, we do not consider this an indication for antiviral or immunosuppressive therapy. In the absence of strong evidence supporting the use of any specific therapy, we recommend a conservative approach for an immunocompetent patient.

A 10-year-old castrated male Korean shorthair cat weighing 4 kg was referred with signs of insulin-resistant diabetes mellitus based on clinical signs of polyuria, polydipsia, and polyphagia. Diagnosis of pituitary-dependent hyperadrenocorticism (PDH) was made based on results of an adrenocorticotropic hormone stimulation test and a dexamethasone screening test. In addition, plasma concentrations of insulin-like growth factor 1 (IGF-1) increased. Radiography, ultrasonography, and computed tomography (CT) revealed hepatomegaly, renomegaly, and adrenomegaly affecting both adrenal glands as well as multiple cysts in a generally enlarged pancreas. Magnetic resonance imaging (MRI) showed that the cat's pituitary gland was enlarged. The pituitary gland had a predominantly unilateral extension to the left. The signal intensity of the pituitary gland on precontrast T1 weighted images was hypointense compared to that of soft tissue and hyperintense compared to that of cerebrospinal fluid. On T2 weighted images, the pituitary gland was predominantly hypointense with a hyperintense rim. Contrast enhancement of the pituitary gland was not evident, and a mild degree of ring-like enhancement was seen. In addition, mild peritumoral edema was present. This is the first report of a cat with suspected double adenoma of the pituitary gland on the basis of compatible clinical signs, increased serum IGF-1 concentration, PDH, CT images, and MRI findings in diabetic cats with insulin resistance.

Glycogenic hepatopathy (GH) is an uncommon cause of serum transaminase elevation in type I diabetes mellitus (DM). The clinical signs and symptoms of GH are nonspecific, and include abdominal discomfort, mild hepatomegaly, and transaminase elevation. In this report we describe three cases of patients presenting serum transaminase elevation and hepatomegaly with a history of poorly controlled type I DM. All of the cases showed sudden elevation of transaminase to more than 30 times the upper normal range (like in acute hepatitis) followed by sustained fluctuation (like in relapsing hepatitis). However, the patients did not show any symptom or sign of acute hepatitis. We therefore performed a liver biopsy to confirm the cause of liver enzyme elevation, which revealed GH. Clinicians should be aware of GH so as to prevent diagnostic delay and misdiagnosis, and have sufficient insight into GH; this will be aided by the present report of three cases along with a literature review.

We report a case of transient abnormal myelopoiesis in a Down syndrome fetus diagnosed at 28(+3) weeks of gestation that rapidly progressed to intrauterine death 10 days later. Fetal hepatosplenomegaly with cerebral ventriculomegaly, although not specific, may be a suggestive finding of Down syndrome with transient abnormal myelopoiesis. Prompt fetal blood sampling for liver function test and chromosomal analysis are mandatory for early detection and management.

PURPOSE: To evaluate the imaging findings of abdominal extraosseous plasma cell neoplasm. MATERIALS AND METHODS: From April 2000 to January 2005, eight patients (four men, four women; mean age, 50.6 years) with pathologically proved, extraosseous plasma cell neoplasm involving the abdominal organs were included in this study. The diagnoses were based on consensus agreement between two radiologists who retrospectively reviewed CT, ultrasonography, and enteroclysis findings. We evaluated the findings by focusing on the location, size, margin, and enhancement pattern of the lesion, and lymphadenopathy on each image. RESULTS: There were multiple myeloma in four patients and extramedullary plasmacytoma in the remaining four. Involved abdominal organs were the liver (n = 4), spleen (n = 4), lymph node (n = 3), stomach (n = 1), small bowel (n = 1), and colon (n = 1). The hepatic involvement of plasma cell neoplasm presented as a homogeneous, well-defined, solitary mass (n = 1), multiple nodules (n = 1), and hepatomegaly (n = 2). Its involvement of the spleen and lymph node appeared as splenomegaly and lymphadenopathy, respectively. Its involvement of the gastrointestinal tract including the stomach, small bowel, and colon, presented as a homogeneous, diffuse wall thickening or mass in the gastrointestinal tract. CONCLUSION: Abdominal extraosseous plasma cell neoplasm involves occasionally the liver, spleen, and lymph node, and rarely the gastrointestinal tract. When we encounter a well-defined, homogeneous lesion of the abdominal organs in patients diagnosed or suspected as having plasma cell neoplasm, we should consider its involvement of the abdominal organs.

Zellweger syndrome is a lethal autosomal recessive disorder characterized by neonatal hypotonia, neonatal seizure, psychomotor retardation, facial dysmorphism, and hepatomegaly. It is characterized by an absence or marked decrease of the number of peroxisomes. Children with Zellweger syndrome rarely survive their first year of life. Diagnosis depends on demonstration of elevated very long chain fatty acid in plasma and deficient activity of the peroxisomal enzyme. Chorionic villi sampling or the biochemical analysis of amniocytes makes it possible to identify a fetus affected by Zellweger syndrome during the first trimester of pregnancy. We experienced two cases of postnatally diagnosed Zellweger syndrome with mild sonographic abnormalities prenatally and report our cases with a brief review of literature.
