Inflammatory myofibroblastic tumor of the bladder: case report and review of the literature

Inflammatory myofibroblastic tumor (IMT) is a rare tumor with malignant potential, and it has been described in many major organs. However, bladder location is very uncommon. We report the case of a 23-year-old women presented with painless gross hematuria last for 2 weeks. Contrast-enhanced computed tomography (CT) revealed a bladder tumor. The patient underwent a open partial cystectomy and the final pathologic diagnosis was inflammatory myofibroblastic tumor of bladder. Typical IMTs can be locally aggressive, thus close follow-up is necessary.

Pulmonary Inflammatory Myofibroblastic Tumor

Abstract Background Inflammatory myofibroblastic tumor (IMT) is rare intermediate tumor, which happens mostly in children and young adults. Case presentation Reported is the successful treatment of a 29-year-old man presented with progressively dysphagia and weight loss. No other abnormal symptoms were observed. The contrast enhanced computed tomography (CT) revealed a dumbbell-shaped lesion between lung and esophagus. Finally, it was pathologically diagnosed as pulmonary IMT invading to the distal esophagus after operation. The patient underwent partial esophagectomy and left lower lobectomy, and was discharged on 10th postoperative day. Conclusions IMT is a rare lesion that usually occurs in the lung, but pulmonary IMT with distal esophagus invasion has not been described previously. Discriminating untypical symptom, completed resection, pathological expertise and closed follow-up will reach the successful diagnosis and treatment.

Introduction: Inflammatory myofibroblastic tumors (IMTs) arising in the mediastinum is rare. Their etiology remains unknown and their diagnosis is often overlooked before the use of surgery wich allow the propre diagnosis and adequate treatment.Case report: We report a case of 56-year-old woman that had a mediastinal mass discovered after a long complains of chest discomfort. Chest contrast-enhanced computed tomography (CT) showed a heterogeneously enhanced mass in the middle mediastinum The diagnosis was confirmed by histopathology and immunohistochemical study after surgical resection through a thoracotomy The patient was well and had no recurrence 6 months after surgery.Conclusion: The diagnosis of IMT should be kept in mind and included in the differential diagnosis of mediastinal masses.

Abstract Background The aim of this study was to evaluate the safety and efficacy of clip-assisted endoscopic cyanoacrylate injection for gastric varices with a gastrorenal shunt. Methods Records were reviewed of patients with gastric varices and concomitant gastrorenal shunts who underwent clip-assisted endoscopic cyanoacrylate injection at three tertiary centers between April 2016 and October 2018. The assessed outcomes were technical success rate, eradication of gastric varices, cyanoacrylate embolization, and all-cause rebleeding. Results A total of 61 patients were analyzed. The procedure was successful in all patients (100 %). Gastric varices were eradicated in 30 of 33 patients (90.9 %) according to contrast-enhanced computed tomography re-examination within 1 month after the procedure. No symptoms or signs of cyanoacrylate embolization related to the procedure were observed. Four patients (6.6 %) were lost to follow-up. All-cause rebleeding occurred in 13/57 patients (22.8 %) during a median follow-up period of 225 days (interquartile range 114 – 507 days). Conclusions Clip-assisted endoscopic cyanoacrylate injection appeared to be a safe procedure that was convenient and efficacious in the treatment of gastric varices with concomitant gastrorenal shunt.

Purpose: To report the successful endovascular occlusion of a persistent endoleak owing to collateral perfusion in a 1-year-old bifurcated aortic endograft. Methods and Results: An 81-year-old man underwent endovascular repair of a 5.5-cm abdominal aortic aneurysm (AAA) with a bifurcated stent-graft in 1995; collateral perfusion of the excluded aneurysm by retrograde filling of the patent inferior mesenteric artery (IMA) was noted postoperatively. At his 1-year follow-up, the mid-sac endoleak persisted on contrast-enhanced computed tomography. Using the superior mesenteric artery for access, the stump of the IMA was successfully embolized with glue. Conclusions: This case, which highlights the importance of documenting a patent IMA prior to AAA endografting, illustrates one option for the management of persistent collateral perfusion of endovascularly excluded aneurysms.

Introduction The article describes the first experience of performing percutaneous ultrasound (US)-guided cryoablation of renal tumor and assesses the safety and short-term results of treatment. Materials and Methods Twelve patients were subjected to US-guided cryoablation of renal tumor in 2015. The tumor size in 11 patients was up to 3.0 cm (T1а); in one female patient, 4.5 cm (T1b). Tumors were assessed according to the PADUA score. In eight patients, it was 6-7 (low); in three patients, 8-9 (average); in one, 10 (high). All the patients underwent US examination using a FlexFocus 800 apparatus with convex abdominal transducers. Before surgery and 6 months later, all the patients underwent renal Doppler US and contrast-enhanced computed tomography. Results The average cryoablation time was 60 min. Seven operations were performed under spinal anesthesia and five operations under local anesthesia. The follow-up period lasted 8 months on average. According to the ultrasonography and Doppler findings, after 6 months, the tumor (T1a) in 11 patients reduced in size by an average of 7-8 mm and had no blood supply. T1b patient's mass size reduces from 4.5 to 3.7 cm; however, a 1.5 cm area with a high attenuation gradient of the contrast medium was visualized. Later, the patient was subjected to laparoscopic renal resection. Histological finding revealed clear-cell carcinoma. Conclusions We consider percutaneous US-guided cryoablation as a method of choice for patients with stage T1a renal tumor localized on the posterior or lateral surface in the inferior or middle segment without sinus involvement and PADUA <9.
