Neuroenteric cysts, are rare benign endodermal lesions which mostly occur in the central nervous system. We report a case of a neuroenteric cyst in a 30-year-old man who presented with rhinoliquorrhea at the ENT department. After clinical examination, a semisolid mass was revealed in the left nostril. The Computer Tomography Scan revealed a frontal ethmoidal nasal meningoencephalocele with inferior extension into the left nostril. Gadolinium-enhanced T1-weighted MR images showed a well-defined frontal mass with ring-like enhancement and extension into the cribriform plate of the ethmoid bone and into the left nostril. The lesion measured 10/10/20 mm. The tumor was totally resected using a unilateral subfrontal approach. At five months’ follow-up, the patient showed significant amelioration of symptoms and remission of cerebrospinal fluid leakage. Native and Contrast-enhanced Cerebral Computer Tomography, as well as Magnetic Resonance Imaging showed total surgical resection of the cyst. Supratentorial neurenteric cysts involving the anterior fossa are rare. Intracranial neurenteric cysts should be differentiated by any well-demarcated cystic tumors. The gold standard treatment remains complete surgical resection with favorable outcome.

<b><i>Background:</i></b> Endoscopic ultrasound-guided ablation (EUS-A) therapy is a minimally invasive procedure for pancreatic-cystic tumors in patients with preoperative comorbidities or in patients who are not indicated for surgical resection. However, histopathologic characteristics of pancreatic cysts after ablation have not been well-elucidated. <b><i>Methods:</i></b> Here, we analyzed pathological findings of 12 surgically resected pancreatic cysts after EUS-A with ethanol and/or paclitaxel injection. <b><i>Results:</i></b> Mean patient age was 49.8 ± 13.6 years with a 0.3 male/female ratio. Clinical impression before EUS-A was predominantly mucinous cystic neoplasms. Mean cyst size before and after ablation therapy was similar (3.7 ± 1.0 cm vs. 3.4 ± 1.6 cm; <i>p</i> = 0.139). Median duration from EUS-A to surgical resection was 18 (range, 1–59) months. Mean percentage of the residual neoplastic lining epithelial cells were 23.1 ± 37.0%. Of the resected cysts, 8 cases (67%) showed no/minimal (&#x3c;5%) residual lining epithelia, while the remaining 4 cases (33%) showed a wide range of residual mucinous epithelia (20–90%). Ovarian-type stroma was noted in 5 cases (42%). Other histologic features included histiocytic aggregation (67%), stromal hyalinization (67%), diffuse egg shell-like calcification along the cystic wall (58%), and fat necrosis (8%). <b><i>Conclusion:</i></b> Above all, diffuse egg shell-like calcification along the pancreatic cystic walls with residual lining epithelia and/or ovarian-type stroma were characteristics of pancreatic cysts after EUS-A. Therefore, understanding these histologic features will be helpful for precise pathological diagnosis of pancreatic cystic tumor after EUS-A, even without knowing the patient’s history of EUS-A.

The gallbladder volvulus is a rare condition. There have been around 500 cases described worldwide. It is virtually impossible to diagnose it clinically as symptoms are analogous to those of acute cholecystitis. Small proportion of gallbladder volvulus cases get accurately diagnosed preoperatively according to available literature. The imaging such as computer tomography plays a crucial role in diagnosing this condition. Laparoscopic cholecystectomy is considered to be a gold standard treatment for this condition. In our report we present a case of gallbladder volvulus which was successfully diagnosed by means of computer tomography scan

Abstract BACKGROUND Many approaches are used for midline anterior cranial fossa meningioma resection. In the subfrontal approach, the anterior superior sagittal sinus (SSS) is commonly ligated to release the anterior falx. The transbasal approach allows access to the origin of the anterior SSS, allowing for maximum venous preservation. OBJECTIVE To investigate variations in the first and second veins draining into the SSS. METHODS We performed stepwise dissections for a transbasal level 1 approach on 8 anatomic specimens. We visualized the first and second veins draining into the sinus and measured the distance from the foramen cecum to these veins. We also measured the orbital bar height to determine the length of sagittal sinus that could be preserved with orbital bar removal. RESULTS The distance between the foramen cecum and the first vein ranged from 4 to 36 mm while the distance to the second vein ranged from 6 to 48 mm. The mean orbital bar height was 26.4 mm. Based on these measurements, with a traditional bicoronal craniotomy without orbital bar removal, 81% of first veins and 58% of second veins would be sacrificed. CONCLUSION A supraorbital bar or nasofrontal osteotomy, part of the transbasal skull base approach, is helpful to preserve the first and second veins when ligating the anterior SSS. Based on this study, it may be difficult to preserve these veins without orbital bar removal. Preservation of these veins may be of clinical importance when approaching midline anterior fossa pathologies.

349 Background: An increasing number of nonfunctioning, early-stage pancreatic neuroendocrine tumors are detected incidentally as patients undergo radiographic procedures for unrelated indications. Endoscopic sonography with fine-needle aspiration now enables nonoperative biopsy of tumors smaller than 1 cm in diameter. It is unclear whether the risks of partial pancreatectomy or enucleation exceed the risks of surveillance in patients with these neoplasms. Methods: We performed a database search of patients with pancreatic neuroendocrine tumors treated at the H. Lee Moffitt Cancer Center in order to evaluate outcomes of patients with stage I tumors who did not undergo surgical resection. Results: Four patients were identified who elected to undergo surveillance of their stage I tumors instead of surgical resection. All had been diagnosed via endoscopic ultrasound-guided fine-needle aspiration. The tumor sizes were 7 mm, 12 mm, 13 mm, and 15 mm at initial diagnosis. Three tumors were cystic and one was solid. Three were located in the body of the pancreas and one in the tail. In two patients, the Ki-67 index was measured and was <1%. With a median of follow-up of two years, none of the patients experienced tumor growth. All three patients with cystic tumors experienced shrinkage of their tumors following the diagnostic needle aspiration and did not experience subsequent increase in size (Table). Conclusions: Surveillance may be an appropriate strategy for management of incidentally discovered, stage I pancreatic neuroendocrine tumors.

e16125 Background: Adrenocortical carcinoma (ACC) is a rare tumor with an incidence of 1.5–2 per million people per year. It has a poor prognosis with an overall 5-year mortality of 75-80%. The treatment of choice for a localized primary or recurrent tumor is radical surgical resection. However, patients with recurrent or metastatic disease are infrequently cured by surgery alone and chemotherapy has limited benefits. Little is known about the growth rate of metastatic lesions or how disease burden varies among patients, which poses a considerable obstacle in patient care as 17–53% of patients present with distant metastases at the time of diagnosis. Most ACC metastases are found in the liver, lung, bone, and retroperitoneum. Methods: This study retrospectively analyzed the growth rate of metastatic ACC lesions in the lung, liver, lymph nodes, and adrenal bed using serial two-dimensional segmentation of computer tomography images from 10 patients seen at the National Institutes of Health. All patients were females (mean age of 61 years; range, 49–70 years) who had an ACC diagnosis for a mean of 7 years (range, 3–14 years). Only lesions that exhibited FGD-PET avidity were included with up to five lesions per organ recorded. Results: Of the 10 patients, 7 showed metastatic disease at primary diagnosis, although all patients developed recurrent and/or distant metastatic lesions throughout the course of their disease (3 patients had lung lesions, 6 had liver lesions, 8 had adrenal bed recurrence, and 5 had lymph node involvement). Compared over a 6-month period without treatment alteration (change in chemotherapy, surgical intervention, or ablation) lung lesions increased by 11.6%, liver lesions decreased by 17.9%, retroperitoneal lesions increased by 69.25%, and lymph node lesions increased by 9.2%. Conclusions: Treatment of metastatic lesions, particularly in the liver, can increase long-term survival. Understanding growth rates of metastatic tumors may lead to improved treatment of patients with ACC.
