Anticoagulant-induced intramural intestinal hematoma

Intramural hematoma of the intestine is a rare complication of anticoagulant therapy. We evaluated 7 nontrauma patients with intramural hematoma of the intestine diagnosed at our institution between May 1998 and June 2001. All of the patients were receiving long-term anticoagulant therapy for previous diseases. All 7 patients had abdominal pain, 6 had additional symptoms of nausea and vomiting, and 4 had melanotic stools at admission. Six of the patients had abnormal coagulation parameters. Both abdominal ultrasonography (US) and computerized tomography (CT) showed the exact pathology in all patients. Five of the 7 patients were treated, nonoperatively, and the other patients underwent surgery. All of the patients were followed with abdominal US and CT (mean 12 = months), with complete resolution of their intramural hematomas. Abdominal US and CT evaluation performed together will help the accuracy of diagnosis of intramural hematoma, but nonoperative therapy is the treatment of choice, with surgery indicated if generalized peritonitis or intestinal obstruction develops.

Prevalence of epididymal, seminal vesicle, prostate, and testicular cysts in autosomal dominant polycystic kidney disease

OBJECTIVES To assess the prevalence of cysts in the epididymis, seminal vesicles, prostate, and testes of patients with autosomal dominant polycystic kidney disease (ADPKD) and determine their clinical significance. Extrarenal cystic involvement is a well-known manifestation of ADPKD. Although a few reports exist about cysts in the epididymis, seminal vesicles, prostate, and testes, the true prevalence of cysts in these organs is not well known. METHODS A prospective study, consisting of 104 male patients and 62 male controls, was designed at three medical centers to evaluate the prevalence of epididymal, seminal vesicle, prostatic, and testicular cysts in patients with ADPKD by abdominal, transrectal, and scrotal ultrasound examinations. RESULTS Among the 104 patients, epididymal cysts were present in 19 (18%), seminal vesicle cysts were present in 41 (39%), and prostatic cysts were present in 7 patients (7%); the proportion in the control group was 24% (P >0.05), 2% (P <0.01), and 5% (P >0.05), respectively. Testicular cysts were detected in only 3 control patients. Of the 104 patients, 96 were married, and primary infertility was present in 5 patients (5%). CONCLUSIONS We suggest that seminal vesicle cysts are frequent in ADPKD; epididymal cysts are not uncommon in ADPKD, but the frequency is not higher than in the control group; ADPKD should be looked for in patients with seminal vesicle cysts; and additional studies are necessary to evaluate the association between epididymal and seminal vesicle cysts and infertility in patients with ADPKD.

MR imaging and MR angiography in vascular Behçet’s disease

The aims of this study are to demonstrate the ability of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) in the diagnosis and evaluation of vascular involvement in Behçets disease. Twelve patients with vascular involvement due to Behçets disease were included in this study. We believe that MRI and MRA are safe and noninvasive methods that can be used to confirm and monitor vascular Behçets disease.

Behçet's disease and amyloidosis. Review of the literature.

In this report, we present a patient with BD, amyloidosis and end-stage-renal-disease and discuss the literature on BD and amyloidosis. Forty-four patients with BD and amyloidosis are described in the literature. The type of amyloid fibrils were studied in 27 of this 44 patients and all were AA. The interval between the onset of first symptom of BD and the diagnosis of amyloidosis ranged from one to 27 years. This clinical observation and AA type amyloid fibrils in BD suggest that amyloidosis is secondary to inflammation. Behçets disease should be considered in the differential diagnosis of AA amyloidosis.

Asynchronous Bilateral Ovarian Torsion. A Case Report and Mini Review

BACKGROUND Adnexal torsion is a serious condition and delay in surgical intervention may result in loss of ovary. Children and adolescents who have suffered from uterine adnexal torsion may be at risk for asynchronous torsion of the contralateral adnexa. CASE We report the case of asynchronous bilateral ovarian torsion in a 9-year-old girl, resulting in right and subsequently left salpingo-oophorectomy. CONCLUSION The diagnosis of ovarian torsion often is delayed. When ovarian torsion is suspected, laparoscopy should be performed without delay, and conservative management should be strongly considered to prevent surgical castration. Oophoropexy of the ipsilateral and contralateral ovary should be considered to prevent a recurrent torsion.

Coumadin-Induced Renal and Retroperitoneal Hemorrhage

Principles. Coumadin-induced renal and retroperitoneal hemorrhages are rare. Clinical and laboratory findings are not specific for the diagnosis. Computed tomography (CT) has some advantages in the evaluation of these patients. The aim of this study is to report our experience regarding renal and retroperitoneal hemorrhage due to Coumadin, and describe clinical and CT findings, treatment, and prognosis of the patients. Methods. We reviewed our CT archive to search patients with renal and retroperitoneal hemorrhage caused by Coumadin treatment retrospectively. A total of seven patients with Coumadin-induced renal and retroperitoneal hemorrhages were included in this study. Results. Four patients had abdominal pain, two patients had hematuria, and one patient had abdominal pain and hematuria. There was retroperitoneal hemorrhage in three patients on abdominal CT. One patient had hemorrhage in the renal pelvis and the jejunum, another had hemorrhage in the renal pelvis and the perirenal area, and another had hemorrhage in the perirenal area and the retroperitoneal region. In the last patient with hematuria, there was no hemorrhage. None of the patients had a lesion-causing hemorrhage. Coumadin was stopped, and vitamin K and fresh-frozen plasma were given to patient. One patient with massive retroperitoneal hemorrhage died, whereas other patients were successfully treated using conservative approaches. Conclusions. Hematuria and abdominal pain are the most common complaints in Coumadin-induced renal and retroperitoneal hemorrhage. CT can be the first imaging modality in these patients due to its ability to directly evaluate all peritoneal and retroperitoneal structures. It also allows evaluation of any underlying lesion that can cause hemorrhage from the renal area and the urinary tract. Conservative treatment is the first choice, and prognosis is good when diagnosed early.

Pulmonary and cerebral oil embolism after hysterosalpingography with oil soluble contrast medium

Abstract:  Pulmonary oil embolism (POE) is an extremely rare complication of hysterosalpingography (HSG). A case report of a 29‐year‐old woman who developed confusion and respiratory distress 12 h after HSG is presented. Intravasation of the contrast material was obvious on the HSG. High‐resolution CT revealed ground‐glass pattern predominantly in the lower lobes. The clinical picture and radiological findings improved on the tenth hospital day. It is believed that this is the first report of high‐resolution CT findings in a case complicating HSG.

Bilateral adrenal cystic neuroblastoma with superior vena cava syndrome and massive intracystic haemorrhage

Bilateral cystic adrenal tumours are a rare presentation of neuroblastoma. Intratumoural haemorrhage is a frequent finding in neuroblastoma, but is rarely symptomatic. We present an 11-month-old girl with predominantly cystic bilateral neuroblastomas and distant lymph-node metastasis. Massive intracystic haemorrhage and superior vena cava (SVC) syndrome were ominous prognostic factors, leading to death. Large tumours with intracystic haemorrhage might require a conservative approach.

Keratocystic odontogenic tumor: case report with CT and ultrasonography findings

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. KCOT is most commonly occurred in mandible and demonstrate a unilocular, round, oval, scalloped radiolucent area, while large lesions may appear multilocular. An important characteristic of KCOT is its propensity to grow in an antero-posterior direction within medullary cavity of bone causing minimal expansion. Definitive diagnosis relies on histological examination. In this report, a KCOT that had an expansion both buccal and lingual cortical bone is described including its features in computed tomography and ultrasonographic exams. The lesion was removed surgically via an intraoral approach under local anesthesia and histologically reported as a KCOT.

The advantages of MRI and MRA for diagnosing Behçet's disease and internal jugular vein thrombosis

Behçets disease is a multisystem disorder characterized by recurrent aphtous ulcers of mucosal membranes, skin lesions, and vasculitis. The prevalence of vascular involvement is about 25% and this is the leading cause of death in Behçets disease. Jugular vein involvement is an unusual manifestation of Behçets disease. Medical insertion of needles into veins or arteries can induce thrombosis or aneurysms. Thus, diagnostic studies or therapy can aggravate the disease and even be fatal. We report a patient with Behçets disease and rare internal jugular vein thrombosis. We also demonstrate the ability of noninvasive magnetic resonance imaging and magnetic resonance angiography to aid in the diagnosis and evaluation of vascular involvement in Behçets disease, without risking iatrogenic complications.
