Gastrointestinal Stromal Tumors with Unusual Localization: Report of Three Cases with a Brief Literature Review

The most common tumors derived from the mesenchyme of the gastrointestinal system are stromal tumors. These tumors are typically seen in the stomach and small intestine and less frequently in the colon, rectum and esophagus and are very rarely located outside the gastrointestinal system. Cure is provided with complete surgical resection with resection borders free of tumor. Tumor size, mitotic index, localization, CD117 and CD34 negativity in immunohistochemical studies, mucosal ulceration and presence of necrosis help to predict recurrence of the illness and patient survival. In high-risk gastrointestinal stromal tumors (GISTs) there is an increased rate of recurrence and shortened survival despite complete surgical resection. Thus patients with a high-risk GIST should be given adjuvant therapy with imatinib mesylate. Sunitinib maleate is another FDA-approved agent only for cases who cannot tolerate imatinib or who are resistant to it. Herein we present three cases with GISTs in different locations of the gastrointestinal system with a review of the relevant literature

Spontaneous intracranial hypotension syndrome in a patient with Marfan syndrome and autosomal dominant polycystic kidney disease

Intracranial hypotension is typically manifested by orthostatic headache. The most frequent underlying factor is cerebrospinal fluid leakage. It has been suggested that dural structural weakness in some connective tissue diseases may be responsible for dural tears and diverticula and consequently leakage. We present a case of spontaneous intracranial hypotension associated with Marfan syndrome and autosomal dominant polycystic kidney disease. The patient was treated successfully with epidural autologous blood patch. Dural involvements of these hereditary connective tissue diseases are also discussed

Two-year experience with cell salvage in total hip arthroplasty

ABSTRACT BACKGROUND AND OBJECTIVE: The aim of this study was to determine the efficacy of the cell salvage system in total hip arthroplasty surgeries and whether the cell salvage system can reduce the allogeneic blood transfusion requirement in total hip arthroplasty patients. METHODS: We reviewed retrospectively the medical records of patients who underwent hip arthroplasty surgeries between 2010 and 2012 in a university hospital. A total of 181 arthroplasty patients were enrolled in our study. RESULTS: In the cell salvage group, the mean perioperative rate of allogeneic blood transfusion was significantly lower (92.53 ± 111.88 mL) than that in the control group (170.14 ± 116.79 mL; p < 0.001). When the mean postoperative transfusion rates were compared, the cell salvage group had lower values (125.37 ± 193.33 mL) than the control group (152.22 ± 208.37 mL), although the difference was not statistically significant. The number of patients receiving allogeneic blood transfusion in the CS group (n = 29; 43.2%) was also significantly lower than control group (n = 56; 73.6%; p < 0.05). In the logistic regression analysis, perioperative amount of transfusion, odds ratio (OR) -4.257 (95% CI -0.502 to 0.184) and operation time, OR: 2.720 (95% CI 0.001-0.004) were independent risk factors for the usage of cell salvage system. CONCLUSION: Cell salvage is an effective strategy for reducing the need for allogeneic blood transfusion in the perioperative setting; it provides support to patient blood management interventions. Thus, we recommend the cell salvage system for use in total hip arthroplasty surgeries to reduce the need for allogeneic blood transfusion, if possible

Small bowel intussusception in a pregnant woman with Peutz-Jeghers Syndrome

Intussusception is the most frequent complication of Peutz-Jeghers Syndrome (PJS), but usually seen in child age. It is a predictable, but infrequent complication in adults with PJS. However, there is no report about intussusception in pregnancy period secondary to Peutz-Jeghers (PJ) polyps in the literature. In this paper, we present a rare intussusception case in a pregnant woman with PJS, which was diagnosed with magnetic resonance imaging, and discuss this condition with a brief literature review

Magnetic resonance imaging of rheumatoid meningitis: a case report and literature review

Rheumatoid meningitis is a rare and serious complication of rheumatoid arthritis (RA) with high mortality rate. Clinical importance of the disease is high because diagnosis is difficult, and the disease is treatable if diagnosed successfully. We present the clinical and cranial magnetic resonance imaging findings of 62-year-old female patient with RA who has been followed up for 4 years

Pathological Contrast Enhancement of the Oculomotor and Trigeminal Nerves Caused by Intracranial Hypotension Syndrome

The typical symptom of intracranial hypotension syndrome is orthostatic headache. The headache may also be accompanied by neck pain and stiffness, low backache, radicular symptoms, quadriplegia, interscapular pain, nausea/vomiting, and cranial nerve involvement symptoms (hearing and visual problems, face pain and numbness, hypogeusia). Radiologically, on cranial magnetic resonance imaging, intracranial hypotension syndrome is characterized by dural thickening and contrast enhancement, subdural effusion, engorgement of the venous structures, sagging or downward displacement of the brain, and pituitary hyperemia. Although clinical findings related to cranial nerves 3 and 5 have been described in intracranial hypotension, pathological contrast enhancement of these nerves has not. We present a 32-year-old patient whose cranial magnetic resonance imaging shows bilateral pathological contrast enhancement of cranial nerves 3 and 5 and describe a new imaging finding in intracranial hypotension syndrome

Polycystic Kidney Disease Accompanied by Unilateral Renal Agenesis and Ulcerative Colitis: Case Report

Autosomal dominant polycystic kidney disease (ODPKD) is characterized by presence of multiple cysts in kidneys and other organs, and it is the most common hereditary kidney disorder. Approximately 8-10% of all cases progress to end stage renal failure. There may be multiple cysts in different sizes, widespread in the cortex and medulla of both kidneys filling the whole parencyhma. The cysts may also be seen in liver, spleen, pancreas and other organs. Although cases with unilateral ODPKD have been reported in literature, only a few adult cases have been reported with ODPKD accompanied by unilateral renal agenesis. Our case is a 62-year-old male patient who has ODPKD accompanied by unilateral renal agenesis and late-onset ulcerative colitis and who is presented with a review of the literature

Defining the Collateral Flow of Posterior Tibial Artery and Dorsalis Pedis Artery in Ischemic Foot Disease: Is It a Preventing Factor for Ischemia?

Background: Critical limb ischemia, a worldwide prevalent morbidity cause, is mostly secondary to vascular insufficiency due to atherosclerosis. The disease presents with intermittent claudication, which can progress to critical limb ischemia requiring amputation. Research has emphasized that the quality or existence of the pedal arch have a direct effect on wound healing and, therefore, on limb salvage, through the mechanism of collateral vascularization to the ischemic regions

Bladder cancer in an inguinal vesical hernia

A 60-year-old male patient presented with intermittent right-sided scrotal swelling for the last 4 months. On ultrasonography, a fluid-filled cavity extending through the right inguinal canal into the scrotum was noted with inferior displacement of the right testis. Multiple papillary hyperechoic lesions with internal vascularity on Doppler ultrasound were protruding into the fluid-filled cavity. Computed tomography showed herniation of the bladder through the right inguinal canal into the scrotum with mural components in the herniated segment. Hernioplasty followed by transurethral tumor resection showed urothelial carcinoma with invasion into the muscular layer. Vesical herniation through the inguinal canal is uncommon. Additionally, the presence of bladder carcinoma within a herniated portion of the bladder is exceedingly rare
