Dense Mass

Hemangiomas rarely occur in the retropharyngeal space with only several cases reported in the current literature. This article reports the hemangiomas of retropharyngeal space. A 55-year-old woman was referred to our institution for dysphagia. Computed tomography and magnetic resonance imaging of the neck and spine revealed a large, well-circumscribed, dense mass that extended from the retropharyngeal space to the sides of the neck. Patient underwent direct excision of the lesion. Complete regression of symptoms was observed after surgery, with no lesions found on routine 24-month follow-up. Although hemangiomas are relatively common in the head and neck, those that originate in the retropharyngeal space are very rarely observed. These benign tumors have the potential to compress adjacent tissues or organs and thereby produce associated symptoms like dysphagia and dyspnea. We present the reported case of larger hemangiomas of the retropharyngeal space and detail their management.

Liposarcoma is a common soft tissue sarcoma. However, its occurrence in pancreas or stomach is extremely rare. In the present study, a rare case of a 55-year-old female with sclerosing liposarcoma in pancreas and stomach is presented.  Ultrasound, magnetic resonance imaging and computed tomography examinations were performed, which revealed a pancreatic mass. Subsequently, the patient underwent surgical resection of the tail of the pancreas and spleen and partial resection of stomach following the identification of a second mass. After surgery, the patient received no adjuvant treatment. Subsequent to 3 years of clinical follow up, the patient remains alive without recurrence or distant metastasis so far. As far as we know, this is the first reported case of sclerosing liposarcoma involving pancreas and stomach.

Adnexal Pathology

Pelvic pain presents a common diagnostic conundrum with a myriad of causes ranging from benign and trivial to malignant and emergent. We present a case where a mucinous neoplasm of the appendix acted as a mimic for tubular adnexal pathology on imaging. With the associated imaging findings on ultrasound, computed tomography, and magnetic resonance imaging, we wish to raise awareness of mucinous tumors of the appendix when tubular right adnexal pathology is present both in the presence of pelvic or abdominal pain or when noted incidentally. Tubular pathology such as uncomplicated paraovarian cysts or hydrosalpinx is frequently treated conservatively with long-interval follow-up imaging or left to clinical follow-up. Thus, if incorrectly diagnosed as tubular pathology, an appendix mucocele or mucinous neoplasm of the appendix is likely to be undertreated. We wish to clarify some of the confusion around nomenclature and classification of the multiple entities that are comprised by the terms mucocele and mucinous tumor of the appendix.

Laparoscopic Assisted

The present study investigates how computed tomography perfusion scans and magnetic resonance imaging correlates with the histopathological alterations in renal tissue after cryoablation. A total of 15 pigs were subjected to laparoscopic-assisted cryoablation on both kidneys. After intervention, each animal was randomized to a postoperative follow-up period of 1, 2, or 4 weeks, after which computed tomography perfusion and magnetic resonance imaging scans were performed. Immediately after imaging, open bilateral nephrectomy was performed allowing for histopathological examination of the cryolesions. On computed tomography perfusion and magnetic resonance imaging examinations, rim enhancement was observed in the transition zone of the cryolesion 1week after laparoscopic-assisted cryoablation. This rim enhancement was found to subside after 2 and 4 weeks of follow-up, which was consistent with the microscopic examinations revealing of fibrotic scar tissue formation in the peripheral zone of the cryolesion. On T2 magnetic resonance imaging sequences, a thin hypointense rim surrounded the cryolesion, separating it from the adjacent renal parenchyma. Microscopic examinations revealed hemorrhage and later hemosiderin located in the peripheral zone. No nodular or diffuse contrast enhancement was found in the central zone of the cryolesions at any follow-up stage on neither computed tomography perfusion nor magnetic resonance imaging. On microscopic examinations, the central zone was found to consist of coagulative necrosis 1 week after laparoscopic-assisted cryoablation, which was partially replaced by fibrotic scar tissue 4 weeks following laparoscopic-assisted cryoablation. Both computed tomography perfusion and magnetic resonance imaging found the renal collecting system to be involved at all 3 stages of follow-up, but on microscopic examination, the urothelium was found to be intact in all cases. In conclusion, cryoablation effectively destroyed renal parenchyma, leaving the urothelium intact. Both computed tomography perfusion and magnetic resonance imaging reflect the microscopic findings but with some differences, especially regarding the peripheral zone. Magnetic resonance imaging seems an attractive modality for early postoperative follow-up.

A retrorectal epidermoid cyst is an uncommon congenital lesion that arises from the remnants of the embryonic tissues. This type of cyst is difficult to diagnose before surgery. In this study, we report a rare case of a giant retrorectal epidermoid cyst in a 30-year-old woman. Initially, the condition was diagnosed as a perianal abscess and treated with incision and drainage. Since the abscess recurred, a pelvic magnetic resonance imaging was ordered, which revealed an 8.2 cm perianal cyst with appearance not compatible with an abscess. Postsurgical histologic analysis confirmed a retrorectal epidermoid cyst. Postoperative course was uneventful, and the woman was discharged on postoperative day 3. She was doing well at 4 months of follow-up. This report suggests that retrorectal cysts should be considered in cases of recurrent perianal swellings/abscesses.

207 Background: Multi-detector computed tomography using pancreatic protocol (pCT) has been a preferred diagnostic imaging modality before resection of the pancreatic ductal adenocarcinoma (PDAC), because an adjunctive role of liver magnetic resonance imaging (MRI) is still unclear. The current study evaluated whether liver MRI added to pCT can help to select proper surgical candidates, and reduce the risk of early recurrence, eventually result in longer survival in resected PDAC patients. Methods: Among 197 PDAC patients who underwent curative-intended surgery, 167 patients who achieved complete resection with no grossly visible tumor were enrolled retrospectively. All patients had no metastatic lesions on pCT and/or MRI, preoperatively. Among them, 102 patients underwent pCT alone (CT group), and 65 patients liver MRI as well as pCT (MRI group). Results: By adding the liver MRI, hepatic metastases were newly discovered in 3 of 58 patients (5.2%) with no hepatic lesions on pCT and in 17 of 53 patients (32.1%) with indeterminate hepatic lesions on pCT. Among 167 patients who achieved R0/R1 resection, the median overall and disease-free survival were 20.1 vs 29.3 months and 8.5 vs 10.0 months in the CT and the MRI group, respectively (p = 0.011 and = 0.012), during median follow-up of 16.4 months. 80 (78.4%) patients in the CT group and 39 (60.0%) in the MRI group experienced recurrence during follow-up. Cumulative initial hepatic recurrence rate was higher in the CT group than in the MRI group (43.7% vs 18.5% at 1yr and 57.4% vs 26.9% at 2yr, p < 0.001), although the other sites recurrence did not differ in both groups. Conclusions: Liver MRI added to pCT has an incremental value in detecting PDAC hepatic metastases. Furthermore, because PDAC patients who underwent resection after liver MRI as well as pCT expect lower rate of hepatic recurrence and better survival than pCT alone, therefore, liver MRI added to pCT is needed to patients who planned curative resection of PDAC.

ABSTRACT Cavernous hemangioma is a rare tumor of the adult larynx. These hemangiomas are confined to the larynx and generally asymptomatic. We present a rare case of a huge cavernous hemangioma in a 22-year-old patient who presented with stridor and a huge swelling in the neck, of acute onset. Detailed evaluation including 70° Hopkins laryngoscopy, contrastenhanced computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed a vascular malformation with both intra- and extralaryngeal components. The typical findings of hemangioma with its management are highlighted in this article. Postoperatively, patient's voice improved and the stridor was relieved.

Mesenchymal Tumours

Angiomyolipomas are benign mesenchymal tumours originating from the kidney and adrenals. They are rare tumours that can be sporadic and isolated or occur as a part of tuberous sclerosis. These tumours have a high content in the cells, which is pathognomonic for diagnosis using ultrasonography, computed tomography and magnetic resonance imaging. Atypical angiomyolipomas occur with excessive smooth muscle cells and less adipose tissue, and are sensitive to immunohistochemistry studies. Most of these lesions are detected incidentally but some can cause back and abdominal pains if large in size. Larger lesions are also vulnerable to spontaneous or traumatic rupture, causing large retropertitoneal bleeds. Surgery should be considered as the definitive management for larger lesions to avoid associated complications. There have been no reports of any malignant change being reported in any of the lesions but a long follow-up period is still required, given the unknown clinical progression of these rare tumours.
