Background. Solid pseudopapillary neoplasm of the pancreas is an uncommon exocrine pancreatic tumor of epithelial origin, which represents only 1% to 2% of all pancreatic tumors and mainly affects young women. Objective. To describe clinical and imaging features of these rare entity in a symptomatic young woman. Case report. 41-year-old female patient, without morbid history, consulted for intermittent epigastralgia of one-month evolution. Abdominal ultrasound and magnetic resonance imaging demonstrated the presence of a solid-cystic mass of neoplastic appearance in the body-tail of the pancreas. The case was presented to the institutional hepato-biliary committee where surgical resection was decided. Discussion. Although solid pseudopapillary neoplasm of the pancreas are very uncommon pancreatic tumors, it is necessary to keep them within the differential diagnosis on the one hand due to their low but existing malignant potential and on the other hand due to their good prognosis with surgical treatment.

Abstract Background Familial adenomatous polyposis (FAP) is characterized by the presence of hundreds to thousands of colonic polyps, and extracolonic manifestations are likely to occur. Pancreatic tumors are rare extracolonic manifestations in patients with FAP, among which solid-pseudopapillary neoplasm (SPN) are extremely rare. We report here a patient with an SPN of the pancreas found during the follow-up of FAP. Case presentation A 20-year-old woman was diagnosed with FAP 3 years previously by colonoscopy which revealed less than 100 colonic polyps within the entire colon. She complained of left upper abdominal pain and a 10-cm solid and cystic pancreatic tumor was found by computed tomography scan. Solid and cystic components within the tumor were seen on abdominal magnetic resonance imaging. Simultaneous laparoscopic resection of the distal pancreas and subtotal colectomy was performed. Histopathological findings confirmed the pancreatic tumor as an SPN without malignancy. Abnormal staining of beta-catenin was observed by immunohistochemical study. Multiple polyps in the colorectum were not malignant. Molecular biological analysis from peripheral blood samples revealed a decrease in the copy number of the promoter 1A and 1B region of the APC gene, which resulted in decreased expression of the APC gene. Conclusions A rare association of SPN with FAP is reported. The genetic background with relation to beta-catenin abnormalities is interesting to consider tumor development. So far, there are few reports of SPN in a patient with FAP. Both lesions were treated simultaneously by laparoscopic resection.

A 42-year-old man presented with a huge varicocele. The patient was completely asymptomatic and he did not complain of dysuria, perineal discomfort, or ejaculatory pain. During the visit, the mass mimicked a varicocele and during the Valsalva maneuver a reflux was documented by colour Doppler ultrasound and an abdominal ultrasound revealed an agenesis of the right kidney and a 4.5-cm diameter intra-prostatic cyst. An abdominal and pelvis magnetic resonance imaging was then performed, which confirmed the right renal agenesis, with an epididymal enlargement in the body and tail. This is a unique case of Zinner syndrome in which the patient presented with a paratesticular mass mimicking a varicocele.

Rectal Duplication

Rectum is the least common site of gastrointestinal duplication. Up to now fewer than 100 cases have been reported in the literature. We present two infants with cystic rectal duplications manifested with chronic constipation as a main clinical symptom. The first patient was a 4-year-old boy who was admitted to emergency department because of chronic constipation unresponsive to fiber supplements and laxatives. Digital rectal exam revealed mass adjacent to posterior rectal wall. Abdominal ultrasound and magnetic resonance imaging confirmed oval, homogenous and hypoechogenic cystic mass (87x65x60 mm in size) behind the rectum. The size and location of the cystic mass was confirmed by magnetic resonance imaging. The second patient was an 11-month-old boy who was hospitalized due to rectal bleeding. He was suffering from chronic constipation over the last five months. Digital rectal exam revealed a mass behind the rectum. Abdominal ultrasound and computed tomography showed unilocular cyst (33X33 mm in size) in front of the urinary bladder, partly extending into retrorectal space. Both patients were operated on. Postoperative periods were uneventful in both of them. Cystic rectal duplication must be ruled out in all infants with chronic constipation unresponsive to conservative treatment. Different imaging techniques are currently used to determine the precise size and location of duplication. Surgery is the only possible therapy option.

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare neoplasm that accounts for about 1 to 2 per cent of all pancreatic tumors. The aim of this study was to delineate the clinicopathological characteristics and surgical outcomes of solid pseudopapillary neoplasm of the pancreas. We retrospectively reviewed the clinicopathological characteristics and surgical outcomes of 18 patients who underwent surgery for SPN of the pancreas between January 1, 2001 and November 1, 2010. The patient group was comprised of 14 females and four males and the median patient age at diagnosis was 32.4 years (range 10∼68 years). Eleven of the 18 patients were symptomatic at the time of diagnosis. The type of surgery was selected according to the location and presentation of the tumor. The resection margins were negative in all patients. One patient had distant metastasis and recurrent mass node repetitively. She underwent seven operations for recurrence of SPN during the follow-up period of 218 months. Complete surgical excision is the treatment of choice for SPN of the pancreas and can give a good prognosis. Although sometimes patients have repetitive metastases or recurrences, patients undergoing complete surgical excision of the tumor will have a good outcome.

Abstract Solid pseudopapillary neoplasm (SPN) is a rare clinical entity. One third of the patients are asymptomatic and the diagnostic is based on imaging studies (abdominal ultrasound, computed tomography, magnetic resonance imaging) and histological examination of biopsies obtained most frequently by endoscopic ultrasound-guided fine-needle aspiration. In this article we made a short review of the literature and present the imaging and histological aspects found in our patients with SNP.

Solid pseudopapillary neoplasm of the pancreas is a rare tumor of low malignancy that occurs most often in females. The study describes the clinicopathologic characteristics of the tumor and common differential diagnoses. Data were collected from a prospectively maintained database. Of 1661 patients operated for pancreatic tumors between January 2001 and September 2018, 15 patients were recorded. Patients included 12 females and 3 males, median age 40 (range 10 -87) years. Computed tomography or magnetic resonance imaging was diagnostic in eight patients and a preoperative biopsy in eight out of 10 patients. Median tumor size was 5 cm (range 2 -16 cm), 12 tumors were in the head, six in the body, and three in the tail of the gland. All patients except one had radical resection including one with hepatic and lymph node metastases, no patient underwent oncologic treatment. All patients are alive from 17.5 to 209.4 months postoperatively and without recurrence. Radical operation is usually curative and should also be offered to patients with metastases or recurrence as oncologic treatment has limited effect.

Solid Pseudopapillary Neoplasm (SPN) of the pancreas represents 1-3 % of all exocrine pancreatic tumors and is uncommon in children. We report four pediatric patients with SPN where each patient posed a unique diagnostic and therapeutic challenge. We describe these four cases with detailed clinical-radiological-pathological correlations. All patients are female, with a median age 13.5 years. Two patients presented with abdominal pain, one with jaundice and one with an incidental pancreatic mass on abdominal CT scan. Radiological studies included abdominal ultrasound, CT scan and MRI of abdomen. Pancreaticoduodenectomy was performed in three patients and laparoscopic distal pancreatectomy in one patient. Mean tumor size was 4.5 cm (ranged from 1.9 to 11.5 cm). All SPNs were benign on histological exam. One patient developed pancreatic insufficiency post-surgery. No tumor recurrence was observed over a mean follow up period of 1 year. We conclude that diagnosis of SPN in pediatric population can be challenging due to non-specific clinical findings, and surgical removal of the tumor is usually required for definitive histologic diagnosis and treatment. Most tumors are benign and recurrence is very rare.

This research was conducted as a learning alternatives for study of CT (computed tomograpghy) imaging using image reconstruction technique which are inversion matrix, back projection and filtered back projection. CT imaging can produce images of objects that do not overlap. Objects more easily distinguishable although given the relatively low contrast. The image is generated on CT imaging is the result of reconstruction of the original object. Matlab allows us to create and write imaging algorithms easily, easy to undersand and gives applied and exciting other imaging features. In this study, an example cross-sectional image recon-struction performed on the body of prostate tumors using. With these methods, medical prac-titioner (such as oncology clinician, radiographer and medical physicist) allows to simulate the reconstruction of CT images which almost resembles the actual CT visualization techniques.Keywords : computed tomography (CT), image reconstruction, Matlab

As virtually all Europe's major socialist parties re-aligned with their own national governments with the outbreak of World War I, Irish socialist and trade unionist James Connolly found himself internationally isolated by his vociferous opposition to the war. Within Ireland, however, Connolly's energetic and relentless calls to interrupt the imperial transportation and communications networks on which the ‘carnival of murder’ in Europe relied had the converse effect, drawing him into alignment with certain strains of Irish nationalism. Connolly and other socialist republican stalwarts like Helena Molony and Michael Mallin made common cause with advanced Irish nationalism, the one other constituency unamenable to fighting for England under any circumstances. This centripetal gathering together of two minority constituencies – both intrinsically opposed, if not to the war itself, certainly to Irish Party leader John Redmond's offering up of the Irish Volunteers as British cannon fodder – accounts for the “remarkably diverse” social and ideological character of the small executive body responsible for the planning of the Easter Rising: the Irish Republican Brotherhood's military council. In effect, the ideological composition of the body that planned the Easter Rising was shaped by the war's systematic diversion of all individuals and ideologies that could be co-opted by British imperialism through any possible argument or material inducement. Although the majority of those who participated in the Rising did not share Connolly's anti-war, pro-socialist agenda, the Easter 1916 Uprising can nonetheless be understood as, among other things, a near letter-perfect instantiation of Connolly's most steadfast principle: that it was the responsibility of every European socialist to throw onto the gears of the imperialist war machine every wrench on which they could lay their hands.
