Peliosis Hepatis with Hemorrhagic Necrosis and Rupture: a Case Report with Emphasis on the Multi-Detector CT Findings

We report here on an uncommon case of peliosis hepatis with hemorrhagic necrosis that was complicated by massive intrahepatic bleeding and rupture, and treated by emergent right lobectomy. We demonstrate the imaging findings, with emphasis on the triphasic, contrast-enhanced multidetector CT findings, as well as reporting the clinical outcome in a case of peliosis hepatis with fatal hemorrhage.

Imaging Findings of Hepatic Paragonimiasis: A Case Report

Hepatic paragonimiasis is a rare form of ectopic infestation caused by Paragonimus. We experienced a case of hepatic paragonimiasis that showed characteristic imaging findings. CT and MR images showed a cluster of small cysts with rim enhancement in the subcapsular area of the liver. This finding seems to be characteristic for hepatic paragonimiasis, considering imaging findings in paragonimiasis involving other organs.

Percutaneous Transgluteal Drainage of Seminal Vesicle Abscess / 대한비뇨기과학회지

We report on a very rare case of a left seminal vesicle abscess. The patient was a 57-year old male, admitted for the evaluation of dysuria, and with perineal discomfort that had lasted for 3days. One month before admission, he suffered from gonococcal urethritis. The abscess was detected by a pelvic CT, and transrectal ultrasonography. Escherichia coli were found as the causative agent. The abscess was successfully treated by a percutaneous transgluteal approach using pig-tail catheter drainage.

A Case of Secondary Hemochromatosis Revealed in Gastrofiberscopy / 대한소화기내시경학회지

A patient who underwent a transfusion due to an aplastic anemia subsequently experienced secondary hemochromatosis, which is very rare in Korea. The 56 year old female was admitted to our hospital with complaints of general weakness, fatigue, a brown-colored facial complexion, dyspnea upon exertion, and abdominal distension. Laboratory examination disclosed functional impairment of the liver and echocardiography revealed a congestive heart failure pattern. Gastrofiberscopy revealed brown colored gastric mucosa, and a fundal mucosa biopsy revealed a hemosidt pigment in iron stain.

Peri portal Low-Attenuation: A CT Sign of Lymphatic Obstruction

PURPOSE: Periportal low attenuation, defined as a low attenuation rim around the portal vein and its branches which is seen on contrast material-enhanced CT scans, has been described in a variety of conditions. We tried to document that lymphatic obstruction is one of the major cause of periportal low attenuation. METHODS AND MATERIALS: We retrospectively analyzed 57 cases of periportal low attenuation on abdominal CT scans and also reviewed the surgical records in 32 cases. Lymph node enlargement in the hepatoduodenal ligament which is a main lymphatic channel from the liver were analyzed and calculated the ratio of the transeverse diameter between the inferior vena cava and the aorta at the level of right adrenal gland. After complete surgical interruption of the lymphatic drainage from the liver in a dog, follow up CT scans were obtained and correlated with pathologic findings. RESULTS: Fifty patients(88%) had underlying disease which could cause impairment of lymphatic drainage. Periportal low attenuation was identified in several clinical conditions, including surgical lymph node dissection, lymphadenopathy in the hepatoduodenal ligament, blunt trauma. In animal model, CT scan showed prominent periportal low attenuation at 5 days after surgery. Histologic examination revealed numerous dilated lymphatic vessels and a marked lymphedema in the connective tissues surrounding the portal vein and its major branches. CONCLUSION: One of the major.cuase of periportal low attenuation was impaired lymphatic drainage and periportal low attenuation corresponding to the numerous dilated lymphatic vessels and a marked lymphedema in the connective tissues surrounding the portal vein and its major branches.
