Value of Manganese-Enhanced T1- and T2-Weighted MR Cholangiography for Differentiating Cystic Parenchymal Lesions from Cystic Abnormalities which Communicate with Bile Ducts

We present a case report to show how manganese-enhanced T1- and T2-weighted MR cholangiography could differentiate cystic parenchymal lesions from cystic abnormalities which communicate with the bile ducts

Mucinous cystadenoma of the liver with ovarian-like stroma: the need for complete resection

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma

Oleothorax

An 84-year-old woman presented with exertional dyspnoe, productive cough, but absence of chills, night sweats, or fever. Physical examination was unremarkable except for dullness and auscultatory absence of breath sounds over the right upper hemithorax. The patient’s previous medical history revealed the diagnosis of pulmonary tuberculosis at the age of 21. At that time, she was treated successfully with right artificial pneumothoraces and finally with “antiseptic oil”, but the patient was lost to follow-up thereafter

MR imaging of hepatic lymphangioma

A case of primary hepatic lymphangioma with a microcystic component was incidentally found in a 75-year-old woman. Although ultrasonography (US) and computed tomography (CT) showed a mixed lesion including cystic and solid components, magnetic resonance imaging (MRI) demonstrated the morphologic characteristics of the lesion better than other modalities

A primer to common major gastrointestinal post-surgical anatomy on CT—a pictorial review

The post-operative abdomen can be challenging and knowledge of normal post-operative anatomy is important for diagnosing complications. The aim of this pictorial essay is to describe a few selected common, major gastrointestinal surgeries, their clinical indications and depict their normal post-operative computed tomography (CT) appearance. This essay provides some clues to identify the surgeries, which can be helpful especially when surgical history is lacking: recognition of the organ(s) involved, determination of what was resected and familiarity with the type of anastomoses used
