Emphysematous epididymitis as presentation of unusual seminal vesicle fistula secondary to sigmoid diverticulitis: case report.

This case report describes a sigmoid diverticulitis with torpid development, long-term symptoms of bladder irritability, and an emphysematous epididymitis caused by a direct seminal vesicle fistula. The diagnosis was suggested by scrotal ultrasound visualizing gas in the scrotum; the complex pelvic fistulous tract was specifically delineated by multislice computed tomography. This may be the first reported case of seminal vesicle fistula directly related to colonic diverticulitis and causing emphysematous epididymitis.

US and CT diagnosis of a twisted lipomatous appendage of the falciform ligament.

Pathologic conditions of the falciform ligament leading to surgical intervention are extremely uncommon. We report a case of twisted lipomatous appendage of this ligament, demonstrated by US and CT. To our knowledge, there have been no previous reports of this entity. The extraperitoneal nature of the lesion was found by realtime sonography, but CT only was able to characterize its lipomatous nature and relationship with the falciform ligament. This lesion should be considered in the differential diagnosis of intra-abdominal focal fat infarction (IFFI), a recent vocable essentially regrouping infarction of omentum and epiploic appendages.

Hazards of laparoscopic adrenalectomy for Conn's adenoma. When enthusiasm turns to tragedy.

A 74-year-old man with primary aldosteronism had a small tumor (27 x 23 mm) of his right adrenal gland successfully removed by a transperitoneal laparoscopy. Despite absence of malignancy in the resected tumor and complete relief of all symptoms in the immediate postoperative period, recurrence occurred 6 months later. The tumor behaved as a carcinoma spread in the peritoneal cavity, and the patient eventually died with peritoneal carcinomatosis. We suggest that the laparoscopic technique coupled with pneumoperitoneum may have favored this recurrence.

[Diagnosis of non-hiatal diaphragmatic hernia using helical computed tomography].

The authors report the cases of two patients with non traumatic quiescent diaphragmatic hernias who presented with delayed but classical acute gastrointestinal complications. Their only predisposing factor was previous surgery of the left upper quadrant. The diagnosis, suspected on chest radiographs, was promptly performed by helical CT with multiplanar reconstructions (MPVR) and maximal intensity projections (MIP). The exact nature and relationship of the herniated organs, the precise site and size of the diaphragmatic defects were depicted with a noteworthy effectiveness allowing a prompt surgical treatment. Technical guidelines for helical CT of the diaphragm are purposed and the typical CT signs of diaphragmatic hernias are reviewed. The authors also emphasize the advantages of helical CT over other radiological procedures and confirm it as the actual standard for diagnosis of diaphragmatic diseases.

[Strangulated intestinal Spigelian hernia].

Spigelian hernia, an uncommon hernia of the anterior abdominal wall, has serious complications in a high percentage of cases. The diagnosis is often difficult because the symptoms can be insidious or simulate those of more classical lower quadrant abdominal diseases. Furthermore, the clinical findings are often nonspecific. We report a case of Spigelian hernia complicated by acute strangulation diagnosed by ultrasound. The anatomic features and the physiopathology are reviewed and illustrated by another typical case diagnosed by CT. CT is superior to sonography in showing the defect of the abdominal wall, in identifying the contents of the hernial sac and in discovering abnormalities in other areas of the abdomen. Sonography also generally appears adequate in showing a parietal defect. We therefore recommend systematic ultrasonographic examination of the abdominal wall in all doubtful cases of undiagnosed abdominal pain with vague gastro-intestinal symptoms.

Prevention of acute cyclosporine nephrotoxicity by atrial natriuretic factor after ischemia in the rat.

The present experimental study investigates whether the atrial natriuretic factor (ANF) is able to prevent the nephrotoxic effects of cyclosporine infused after 30 min of warm renal ischemia in the rat. At 2 hr after the end of ischemia, the glomerular filtration rate was improved by an ANF infusion: 390 +/- 19 microliters/min/100 g versus 298.3 +/- 31 microliters/min/100 g in ANF and saline-infused rats, respectively (P less than 0.05). Intravenous CsA infusion at a dose of 2.5 mg/kg/day produced a more pronounced fall in GFR when compared with the control: 205.4 +/- 19.7 microliters/min/100 g versus 298.3 +/- 31 microliters/min/100 g in CsA and saline, respectively (P less than 0.05). In contrast, a synthetic rat atriopeptin III (0.5 microgram/kg/min) infusion after ischemia given together with CsA prevented its deleterious effects upon GFR: 316 +/- 22 microliters/min/100 g versus 205.4 +/- 19 microliters/min/100 g in ANF/CsA versus CsA alone (P less than 0.001). Moreover, the natriuretic ANF effects remained unaffected by high plasma CsA peak levels: indeed, other parameters of renal function--urinary flow, urinary sodium concentration and excretion rates, and urinary sodium reabsorption and fractional excretion rates, were significantly increased in ANF alone or CsA/ANF groups. These preliminary results suggest that ANF may be useful in renal transplantation or in the management of patients given large doses of CsA (liver or heart transplant) since, despite nephrotoxic CsA levels (greater than 1500 ng/ml), ANF provides an improved GFR and tubular function after ischemia.

Beneficial effect of atrial natriuretic factor on ischemically injured kidneys in the rat. A new approach to improve early renal function.

In a rat experimental study we investigated whether the atrial natriuretic peptide by itself is able to improve early renal function after an ischemic injury. Two groups of Wistar male rats underwent a right nephrectomy and a left renal artery occlusion for 30 min and were infused for 2 hr after ischemia with isotonic saline or rat atrial natriuretic peptides (alpha ANF: 28 amino acids (AP 28) and atriopeptin III (AP 24): 24 amino acids). ANF infusion increased the urinary flow (P less than 0.001), the urinary sodium concentration (P less than 0.001), the sodium excretion rate (P less than 0.0001), and improved the glomerular filtration rate (GFR) recovery (P less than 0.02) determined at the end of the 2-hr infusion period. AP 24 exhibited higher natriuretics activities than AP 28. The effect of both peptides upon GFR recovery was equivalent. These effects of ANF observed after acute ischemia suggest that this peptide may be beneficial on the resumption of renal function in the early phases following transplantation.

Complicated Meckel's diverticulum diagnosed preoperatively in three cases by complementing CT with detailed us studies.

The clinical and imaging features of Meckel's diverticulum of the adult are reviewed through the report of three complicated cases, one presenting with perforation, the second with intestinal bleeding, and the third with intestinal occlusion due to phytobezoar impaction. Intradiverticular heterotopy of gastric mucosa was the responsible common denominator for the first two cases. Intradiverticular calcified entheroliths were also found in the second case. Obstruction due to a phytobezoar as observed in the third case is a very rare presentation. This report clearly emphasizes and encourages the approach of this difficult diagnosis by combined CT and US imaging.

Giant splenic artery aneurysm presenting as unusual cause of obstructive jaundice.

Giant splenic aneurysms larger than 8 cm (GSAA) are rare and often asymptomatic but present an increased risk of dramatic rupture, a life-threatening complication. The management of these aneurysms is especially challenging. We probably report the first case of GSAA revealed by clinical mechanical jaundice due to direct compression of the biliary tree. The lesion was diagnosed during abdominal ultrasound in a 68-year-old patient but determination of the specific splenic origin and extensive anatomic preoperative evaluation were achieved by MDCT. The case illustrates the new high quality performances of MDCT in the evaluation of complex vascular abdominal situations and is presented with a brief review of the relevant literature.
