    Abstract A Dieulafoy lesion describes a tortuous, submucosal artery in the gastrointestinal tract--most commonly the posterior stomach--that penetrates through the mucosa over time, eventually perforating to cause severe gastrointestinal bleeding. Due to its insidious onset, tendency to cause intermittent but severe bleeding, and difficulty of endoscopic diagnosis, Dieulafoy lesion has a very high mortality rate. Although originally thought not to be a radiologically diagnosable entity, Dieulafoy lesions can be seen at enhanced CT of the abdomen. The purpose of this review is to summarize the pathophysiology, epidemiology, diagnosis, and management of Dieulafoy lesions with a focus on diagnostic findings at enhanced CT imaging.

    Abstract Pheochromocytomas are adrenal tumors that are diagnosed with time-consuming 24-h urine collection studies. Adrenal hemorrhage is a rare but serious complication of pheochromocytomas that has been reported in only about 50 cases [Sutton MG, Sheps SG, Lie JT. Prevalence of clinically unsuspected pheochromocytomas. Review of a 50-year autopsy series. Mayo Clin Proc 1981;56:354-360]. We had a patient with a classic presentation of pheochromocytoma complicated with hypertensive crisis leading to spontaneous adrenal hemorrhage. We report the computed tomographic (CT) findings of ruptured pheochromocytoma that helped us in early detection and treatment of this life-threatening complication.

    Abstract Purpose: Despite advances in various treatment modalities, surgical resection for pancreatic ductal adenocarcinoma (PDA) remains the only curative treatment. Data remains limited regarding survival rates for resectable PDA when managed by a multidisciplinary pancreas conference (MDPC). The aim of this study is to assess survival rates, identify significant predictors of mortality, and assess the benefits of adjuvant chemotherapy for resectable PDA following presentation at a MDPC.
    Methods: All patients presented from April 2013 to August 2016 with resectable PDA were discussed at a MDPC at a tertiary care center and were followed prospectively until November 2017. Survival analysis was performed using Kaplan-Meier for age, tumor size, tumor differentiation, T-stage, lymph node status, and completion of adjuvant chemotherapy cycles. Independent predictors of survival were determined using multivariate Cox regression modeling.
    Results: After MDPC consensus and exclusions, total of 64 patients underwent successful surgery. Amongst this cohort, 1-, 2-, and 3-year survival was 78.13%, 46.30%, and 27.27%, respectively. A total of 37 patients (58%) initiated and 16 patients (25%) finished chemotherapy following surgery. Log-rank analysis revealed that tumor size, age, surgical margins, lymph node status, and number of adjuvant chemotherapy cycles received significantly influenced post-operative survival. Tumor size (p < 0.001), lymph node status (p = 0.035), and number of adjuvant chemotherapy cycles (p = 0.041) remained significant after multivariate Cox regression model.
    Conclusions: Our results suggest that patients with PDA with tumor size > 50 mm and/or lymph node involvement have poor outcomes despite being surgically resectable. Successful completion of adjuvant chemotherapy has better survival outcomes as compared with incomplete or no adjuvant chemotherapy. The role of alternative management such as down-staging with neoadjuvant therapy should be considered.

    Abstract Computed tomography (CT) and magnetic resonance imaging (MRI) were used preoperatively to stage the extent of a diffuse rectal hemangioma in a 37-year-old man with recurrent rectal bleeding. On T2-weighted MR scans, the lesion demonstrated a heterogenous signal intensity with large portions displaying the hyperintensity characteristic of hemangiomas of solid organs. MRI did not depict calcified phleboliths evident on CT and barium enema.

    Abstract A diagnosis of paroxysmal nocturnal hemoglobinuria may be suggested with magnetic resonance imaging, based on the massive renal cortical hemosiderosis that occurs in this disease. A diffuse bilateral depression of renal cortical signal intensity will be observed that is caused mainly by a shortening of the T2 relaxation time of renal cortical protons by the paramagnetic effect of the locally increased ferric ion concentration in the proximal convoluted tubule.

    Abstract An aneurysm of an aberrant right subclavian artery was diagnosed with computed tomography (CT) in a 77-year-old man with an asymptomatic mediastinal mass at admission. Although CT clearly demonstrated this rare congenital anomaly, further radiologic study or surgery was not attempted because of the patient's advanced age and lack of symptoms.

    Abstract All physicians participating in the workup of an infertile patient should be aware of the nonspecificity of the computed tomographic or sonographic finding of a complex adnexal cystic lesion occurring following transvaginal oocyte retrieval for in vitro fertilization. Persistent fever and leukocytosis in conjunction with such lesions should lead to an early presumptive diagnosis of tuboovarian abscess with prompt administration of antibiotic therapy.

    Abstract An aortocoronary saphenous vein graft aneurysm was diagnosed with computed tomography and selective arteriography in a 79-year-old woman with a history of multiple coronary bypass graft surgeries. Aneurysms of saphenous vein grafts are rare complications of bypass surgery but need to be considered when evaluating bypass patients who present with a mediastinal or paracardiac mass.
