1/267. Old and new infarction of an epiploic appendage: ultrasound mimicry of appendicitis.

    Epiploic appendagitis is a self-limiting disease. Depending on its location, it may simulate nearly any acute abdominal condition. The ultrasound and computed tomographic (CT) features are characteristic, enabling ready diagnosis and thus preventing an unnecessary laparotomy. We describe a patient with acute abdominal pain in the right lower quadrant, in whom the combination of an old and fresh infarction of an epiploic appendage simulated appendicitis on ultrasound. Subsequent CT examination made the correct diagnosis.

2/267. Acute torsion of the renal transplant after combined kidney-pancreas transplant.

    BACKGROUND: Surgical complications after combined kidney and pancreas transplantation are a major source of morbidity and mortality. Complications related to the pancreas occur with greater frequency as compared to renal complications. The occurrence in our practice of two cases of renal infarction resulting from torsion about the vascular pedicle led to our retrospective review of similar vascular complications after combined kidney and pancreas transplantation. methods: charts were reviewed retrospectively, and two patients were identified who experienced torsion about the vascular pedicle of an intra-abdominally placed renal allograft. RESULTS: Two patients who had received combined intraperitoneal kidney and pancreas transplantation presented at 16 and 11 months after transplant, respectively, with abdominal pain and decreased urine output. One patient had radiological documentation of abnormal rotation before the graft loss; unfortunately, the significance of this finding was missed. Diagnosis was made in both patients at laparotomy, where the kidneys were infarcted secondary to torsion of the vascular pedicle. Both patients underwent transplant nephrectomy and subsequently received a successful second cadaveric renal transplant. CONCLUSIONS: The mechanism of this complication is a result of the intra-abdominal placement of the kidney, length of the vascular pedicle, excess ureteral length, and paucity of adhesions secondary to steroid administration. These factors contribute to abnormal mobility of the kidney. Technical modifications such as minimizing excess ureteral length and nephropexy may help to avoid this complication.

3/267. Lessons to be learned: a case study approach--a case of temporal arteritis.

    A 71-year-old male presented with a history of sudden partial visual loss in the right eye with an inferior visual field defect over the past 3-4 days. He had no history of headache or of facial pain. Clinical examination confirmed that vision on the right side was reduced to 6/18 and on the left to 6/12. The right eye showed a relative afferent pupillary defect. There was no other abnormality of the anterior segment of either eye. The right retina showed a pale swollen optic disc and a provisional diagnosis of anterior ischaemic optic neuropathy (AION) was made. An urgent erythrocyte sedimentation rate (ESR) was ordered and the patient was asked to return to the eye clinic in one month. However, 16 days later--when it was first recognised that his ESR was elevated to 75 mm in the first hour--the patient was recalled immediately in order to commence systemic steroid treatment; but regrettably, by this time, his right eye had become totally blind. In this case, although the attending doctor made a correct clinical diagnosis on presentation, he failed to act upon the result of the blood test.

4/267. cluster headache-like attack as an opening symptom of a unilateral infarction of the cervical cord: persistent anaesthesia and dysaesthesia to cold stimuli.

    A 54 year old man experienced excruciating left retro-orbital pain with lacrimation and redness of the eye representative of a cluster headache attack. This was followed by left hemiparesis with plegia of the lower limb and left Horner's syndrome. Five days later the hemiparesis recovered while the patient developed hypoanaesthesia to cold stimuli that evoked painful burning dysaesthesia on the right side below the C4 level. MRI disclosed a discrete infarct in the left lateral aspect of the cord at C2 level concomitant to a left vertebral artery thrombosis. This limited infarct and the clinical symptoms suggest a hypoperfusion in the peripheral arterial system of the left hemicord, supplied both by the anterior and posterior spinal arteries. cluster headache-like attack and persistent dysaesthesia to cold stimuli are discussed respectively in view of the central sympathetic involvement and partial spinothalamic system dysfunction.

5/267. Painful swelling of the thigh in a diabetic patient: diabetic muscle infarction.

    A 44-year-old woman with a 5-year history of poorly controlled Type 1 diabetes mellitus presented with a painful, firm and warm swelling in her right thigh. Pain was severe but the patient was not febrile, and had no history of trauma or abnormal exercise. Laboratory tests showed ketoacidosis, major inflammation (erythrocyte sedimentation rate (ESR) = 83 mm/h), normal white blood cell count and normal creatine kinase level. Plain radiographs were normal, and there were no signs of thrombophlebitis at Doppler ultrasound. magnetic resonance imaging (MRI) showed diffuse enlargement and an oedematous pattern of the adductors, vastus medialis, vastus intermedius and sartorius of the right thigh. The patient's symptoms improved dramatically, making biopsy unnecessary, and a diagnosis of diabetic muscular infarction was reached. Idiopathic muscular infarction is a rare and specific complication of diabetes mellitus, typically presenting as a severely painful mass in a lower limb, with high ESR. The diabetes involved is generally poorly controlled longstanding Type 1 diabetes with established microangiopathy. Differential diagnoses include deep vein thrombosis, acute exertional compartment syndrome, muscle rupture, soft tissue abscess, haematoma, sarcoma, inflammatory or calcifying myositis and pyomyositis. In fact, physician awareness should allow early diagnosis on the basis of clinical presentation, routine laboratory tests and MRI, thereby avoiding biopsy and its potential complications as well as unnecessary investigations. rest, symptomatic pain relief and adequate control of diabetes usually ensure progressive total recovery within a few weeks. Recurrences may occur in the same or contralateral limb.

6/267. CT and MRI findings of congestive hepatic infarction caused by tumor thrombus of HCC in the hepatic vein: histopathological correlations.

    We present a case of diffuse hepatocellular carcinoma of the liver with unusual radiological findings. On both CT and MR imaging, the posterior half of the right hepatic lobe showed a unique attenuation/intensity bordered by a clear margin, as if painted in two tones. It appeared to be analogous to "straight border sign," which is known to reflect hepatic venous stoppage. autopsy revealed congestive hepatic infarction congruous with the area of altered attenuation/intensity caused by tumor thrombus in the corresponding branch of the hepatic vein.

7/267. Surgical repair of type B aortic dissection complicated by early postoperative lung vein and artery thrombosis.

    A 24-year old man with marfan syndrome previously operated for abdominal aortic aneurysm and type A dissection sustained a type B dissection. He underwent graft replacement of the descending and upper abdominal aorta, complicated by infarction of the left upper lobe and lobectomy was carried out. The postoperative course was uneventful. The mechanism for this rare complication is discussed.

8/267. Acute renal infarction. Clinical characteristics of 17 patients.

    We analyzed the medical records of patients with an established diagnosis of acute renal infarction to identify predictive parameters of this rare disease. Seventeen patients (8 male) who were admitted to our emergency department between May 1994 and January 1998 were diagnosed by contrast-enhanced computed tomography (CT) as having acute renal infarction (0.007% of all patients). We screened the records of the 17 patients for a history with increased risk for thromboembolism, clinical symptoms, and urine and blood laboratory results known to be associated with acute renal infarction. A history with increased risk for thromboembolism with 1 or more risk factors was found in 14 of 17 patients (82%); risk factors were atrial fibrillation (n = 11), previous embolism (n = 6), mitral stenosis (n = 6), hypertension (n = 9), and ischemic cardiac disease (n = 7). All patients reported persisting pain predominantly from the flank (n = 11), abdomen (n = 4), and lower back (n = 2). On admission, elevated serum lactate dehydrogenase was found in 16 (94%) patients, and hematuria was found in 12 (71%) of 17 patients. After 24 hours all patients showed an elevated serum lactate dehydrogenase, and 14 (82%) had a positive test for hematuria. Our findings suggest that in all patients presenting with the triad--high risk of a thromboembolic event, persisting flank/abdominal/lower back pain, elevated serum levels of lactate dehydrogenase and/or hematuria within 24 hours after pain onset--contrast-enhanced CT should be performed as soon as possible to rule out or to prove acute renal infarction.

9/267. Orbital infarction and melting in a patient with systemic lupus erythematosus.

    OBJECTIVE: To present a patient with systemic lupus erythematosus who developed infarction and melting of the orbit secondary to her systemic disease. DESIGN: A case report. PARTICIPANT: A 61-year-old white woman with a 5-year history of systemic lupus erythematosus. methods: The patient presented with left orbital pain, limitation of extraocular movements, and a fistula from the ethmoid sinus to the upper eyelid. A detailed examination with computerized tomography, ultrasound, and a comprehensive medical evaluation with laboratory testing was performed. Histopathologic analysis with special stains of the orbital tissues was also performed. RESULTS: Histopathologic examination of the biopsy specimens revealed the features of an inflammatory process involving the orbit, similar to a panniculitis. These include a lymphocytic reaction with a predominance of plasma cells, vasculitis with occlusion, and thickening of the vessel walls, necrosis, and hyalinization of fat. CONCLUSION: This is a unique case in which infarction and melting of the entire orbital structures occurred in the presence of systemic lupus erythematosus. The underlying disease process is a lupus-related panniculitis. The authors stress that this is a very rare entity and that other diseases should be ruled out before entertaining this diagnosis.

10/267. uterine perforation resulting in bowel infarction: sharp traumatic bowel and mesenteric injury at the time of pregnancy termination.

    BACKGROUND: By law, elective terminations of pregnancy are not performed in U.S. military institutions. However, in the civilian sector, more than a million abortions are performed each year, some of which are on military beneficiaries. Although complications are relatively rare, patients not uncommonly present for follow-up care to their military installation. We report the case of a patient who presented after a second-trimester elective abortion and was found to have suffered uterine perforation with mesenteric and bowel injury that required bowel resection. CASE: An 18-year-old gravida 1 para 0 female presented from an outlying facility 1 week after elective termination at 18 weeks of gestation with complaints of severe abdominal pain, nausea, and vomiting. Exploratory laparotomy for presumed bowel obstruction revealed uterine perforation and bowel devitalization and necrosis, which required small bowel resection. Fetal bones were discovered within the surgical specimen. CONCLUSION: Morbid, even potentially fatal, complications can occur as a result of pregnancy termination. With second-trimester procedures, perforation can result in injury to abdominal viscera from the perforating instruments or even from sharp fetal bony structures. Military gynecologic surgeons, who are not in abortion practice, must nevertheless be cognizant of the potential for perforation leading to serious visceral injury.
