1/13. A case of "silent" pheochromocytoma presenting as spontaneous retroperitoneal hematoma.pheochromocytoma of the adrenal gland can be the cause of massive and lethal retroperitoneal haemorrhage presenting as acute abdomen. Here we report a case of retroperitoneal hematoma, with concomitant peritoneal spillage, due to the spontaneous rupture of a silent pheochromocytoma. The main clinical findings of this disease will be described. Therapy and prognosis will be also discussed.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/13. Syndromes in amoebic liver abscess.A series of 137 patients with amoebic liver abscess has been studied. Recognition of clearly defined but diverse clinical syndromes was found to be necessary not only in diagnosis but also in planned surgical management. The majority of patients had the classic syndrome of fever, right abdominal or chest pain, hepatomegaly, hepatic tenderness and radiological abnormalities. Other syndromes of presentation included the silent abscess, acute amoebic colitis, the acute abdomen, the intraabdominal lump, the external sinus, pyrexia of obscure origin, obstructive jaundice and renal, pleuro-pulmonary and cardiac symptoms. The syndromes due to an abscess in different parts of the right lobe and in the left lobe of the liver are to some extent distinct. In spite of the varied modes of presentation of amoebic liver abscess, the key to diagnosis is an understanding of the chronological sequence of the disease and its progression from one syndrome to another. Diagnostic methods of value and the mortality are discussed.- - - - - - - - - - ranking = 1.4584017169549keywords = lobe (Clic here for more details about this article) |
3/13. Computed tomography findings in fatal cases of enormous hepatic portal venous gas.AIM: To assess the computed tomography (CT) findings in the patients with hepatic portal venous gas (HPVG) who presented with a short fatal clinical course in our hospital in order to demonstrate if there was any sign for prediction. methods: Between January 1997 and December 2000, CT scan of the abdomen was performed on 949 patients with acute abdominal pain in our emergency department. Five patients were found having HPVG. The CT images and clinical presentations of all these five patients were reviewed. RESULTS: In reviewing the CT findings of the cases, HPVG in bilateral hepatic lobes, abnormal gas in the superior mesenteric veins, small bowel intramural gas, and bowel distension were observed in all patients. Dry gas in multiple branches of the mesenteric vein was also revealed in all cases. All the patients expired due to irreversible septic shock within 48 h after their initial clinical presentation in emergency room. Two patients had acute pancreatitis with grade D and E Balthazar classification and they expired within 24 h due to progressing septic shock under aggressive medical treatment and life support. Two patients with underlying end stage renal disease expired within 48 h even though emergent surgical intervention was undertaken. The excited bowels revealed severe ischemic change. One patient expired only a few hours after the CT examination. CONCLUSION: HPVG is a diagnostic clue in patients with acute abdominal conditions, and CT is the most specific diagnostic tool for its evaluation. The dry mesenteric veins are the suggestive fatal sign, especially for the deteriorating patients, with the direct effect on gastrointestinal perfusion.- - - - - - - - - - ranking = 0.72920085847746keywords = lobe (Clic here for more details about this article) |
4/13. A case of bronchogenic carcinoma presenting with acute abdomen.Colonic metastasis of the bronchogenic carcinoma is quite rare. Here we document an extremely rare presentation of the lung cancer that presented with acute abdomen and was diagnosed as intestinal obstruction due to colon carcinoma initially. He underwent an urgent operation and the obliterating mass in the colon was resected and reported as "colon metastasis from epidermoid carcinoma probably of the lung". Afterwards bronchoscopy revealed an endobronchial lesion in the right lower lobe that was diagnosed as poorly differentiated squamous cell lung carcinoma. In this case, colon metastasis was diagnosed before the diagnosis of the primary disease.- - - - - - - - - - ranking = 0.72920085847746keywords = lobe (Clic here for more details about this article) |
5/13. Second-trimester rudimentary uterine horn pregnancy: rupture after labor induction with misoprostol.BACKGROUND: Uterine anomalies are often first suspected after bimanual or ultrasonographic examination. Currently there are no specific recommendations for further evaluation of asymptomatic women with suspected uterine anomalies in pregnancy. CASE: A young primigravida with a history of an ultrasound diagnosis of bicornuate uterus presented with mild abdominal pain. An ultrasound examination showed a viable 18-week fetus with anhydramnios in the left uterine horn. Labor induction with misoprostol culminated in uterine rupture. At laparotomy, a ruptured left noncommunicating rudimentary uterine horn of a unicornuate uterus was noted. CONCLUSION: Pregnancies within noncommunicating uterine horns significantly increase the risk of potentially catastrophic outcome, therefore, consideration should be given to performing 3-dimensonal ultrasonography and/or magnetic resonance imaging examinations to determine the nature of uterine anomalies. Caution should be exercised if prostaglandins are considered for use in this setting.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/13. Spontaneous rupture of hepatocellular carcinoma in a child: report of a survival.A 10-year-old girl presented in shock with symptoms and signs of an acute abdomen. Spontaneous rupture of a hepatocellular carcinoma was diagnosed by ultrasonography in the emergency room and confirmed by a computed tomography scan. Despite contamination of the peritoneal cavity, aggressive resection of the involved hepatic lobe and the contiguous tissues, without chemotherapy or radiotherapy, has thus far achieved a 3 1/2-year disease-free survival.- - - - - - - - - - ranking = 0.72920085847746keywords = lobe (Clic here for more details about this article) |
7/13. Liver cell adenoma presenting as acute abdomen.A 31-year-old female presented with a sudden onset of acute abdominal pain in the right hypochondrium. Two days later, the patient was in shock and suffering from severe intra-abdominal bleeding. Investigations showed that the bleeding originated in the right lobe of the liver. The patient had been taking oral contraceptives for seven years. She underwent a laparotomy and right lobectomy of the liver which was performed successfully for bleeding cell adenoma. The patient made a full recovery.- - - - - - - - - - ranking = 1.4584017169549keywords = lobe (Clic here for more details about this article) |

9/13. Surgical treatment of lung cancer in patients with human immunodeficiency virus.BACKGROUND. Since January 1986, more than 20 patients have been seen at the University of Miami/Jackson Memorial Medical Center and the Miami veterans Administration Medical Center with concurrent human immunodeficiency virus infection and bronchogenic carcinoma. Four of these patients were treated surgically with curative intent. methods. The histories, records, operative reports, and pathology reports of the 4 patients were reviewed. RESULTS. The 4 surgically treated patients had stage I T1 N0 M0 lung cancer. Three patients had T4 cell counts of less than 200/microL and were managed by lobectomy. These patients died 5, 3 1/2, and 5 months postoperatively. More recently, a fourth patient had a T4 cell count of 963/microL and was treated with wedge resection. He is currently alive 12 months postoperatively. CONCLUSIONS. It is concluded that surgically treated patients with lung cancer, human immunodeficiency virus infection, and T4 cell counts lower than 200/microL have high mortality and morbidity. Although it may be best to base surgical intervention on the stage of the patient's human immunodeficiency virus infection, further analysis is essential to determine which subgroup of human immunodeficiency virus-positive patients, if any, would benefit from surgical treatment of lung cancer.- - - - - - - - - - ranking = 0.72920085847746keywords = lobe (Clic here for more details about this article) |
10/13. An unusual presentation of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing pyogenic liver abscess: report of a case.We describe a rare case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing pyogenic liver abscess in a 59-year-old man. The patient was diagnosed as having a hollow viscus perforation based on a sudden onset of acute abdominal pain along with radiological evidence of bilateral subphrenic feee air (pneumoperitoneum), and underwent an emergency laparotomy. Contrary to expectations, the surgery revealed no perforations of the hollow viscus, but instead a ruptured liver abscess at the dome of the right hepatic lobe was identified associated with suppurative peritonitis. To the best of our knowledge, such a case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing liver abscess is extremely rare.- - - - - - - - - - ranking = 0.72920085847746keywords = lobe (Clic here for more details about this article) |
