Magnetic resonance imaging of non-pueperal total uterine inversion due to a leiomyoma.

We report a case of a 43-year-old woman admitted to the emergency's department for an externalized mass through the vulva. The exploration by magnetic resonance imaging shows complete uterine inversion caused by a giant leiomyoma. Non-puerperal uterine inversion is a rare condition that is usually difficult to diagnose clinically. The role of imaging, specifically magnetic resonance imaging, is essential for the diagnosis, to establish the classification and to adapt the management.

Acute pancreatitis revealing an isolated hydatid pancreatic cyst simulating a pseudocyst: A case report.

Hydatid disease is a worldwide public health problem, especially in endemic countries, caused by the larval stage of Echinococcus granulosis. The pancreatic location of this disease is exceptional, representing only 1% of all possible locations, making this a widely misdiagnosed entity. We report a case of a 42-year-old man with a history of alcoholism and recurring abdominal pain, who presented to the emergency department with acute pancreatitis revealing a hydatid pancreatic cyst mimicking as a pseudocyst of the pancreas. The diagnosis was established using computed tomography and magnetic resonance imaging.

Primary hepatic origin of a neuroendocrine tumor: A rare case report.

Introduction: Neuroendocrine tumors are mainly located in gastrointestinal tract, pancreas and lungs. The primary hepatic origin of neuroendocrine tumors is extremely rare. Case presentation: A 57-year-old female with a history of cholecystectomy presented to our hospital for right upper abdominal pain lasting for 2 months. Abdominal computed tomography revealed a large exophytic soft-tissue mass in the left liver lobe. Tumor markers were within the normal range. Octreoscan confirmed the primary hepatic origin of neuroendocrine tumor. The patient underwent left hepatic resection. Pathological and immunohistochemical examination of the resected specimen showed a well-differentiated grade 2 neuroendocrine tumor. Clinical discussion: Primary hepatic neuroendocrine tumors represent rare hepatic tumors. These tumors may occur at any age with an average of 50 years. Diagnosis algorithm includes two key steps: firstly, the confirmation of the endocrine nature of the tumor and secondly the confirmation of its primary nature. Conclusion: Neuroendocrine tumors are a very rare entity. The primary hepatic location is exceptional. The diagnosis is based on pathological and immunohistochemical examination as well as the result of the octreoscan.

Littoral Cell Angioma of Spleen: A rare case report.

Introduction: Spleen's Littoral Cell Angioma is a rare benign vascular tumor. The main clinical presentation is isolated splenomegaly. Case presentation: we present the case of a 37 years old male patient who suffers from chronic pain in the left hypochondrium.The abdominal examination finds a painful splenomegaly related to a biological bicytopenia. The CT Scan shows a 32 cm splenomegaly.An exploratory laparotomy with splenectomy was performed. The histological and immunohistochemical study confirmed The final diagnosis of Littoral Cell Angioma. Clinical discussion: Isolated splenomegaly of unknown etiology is the main clinical sign. Splenectomy is required for a diagnostic purpose and substratum for histological study. Conclusion: Littoral Cell Angioma of the Spleen is a rare benign vascular tumor, however it should be highlighted by clinical and radiological features, the definitive diagnosis is made upon histological study.

A rare case of penile epidermoid carcinoma.

Penile neoplasms are rare. The main goal of our case report is to demonstrate the important role of imaging in local and regional cancer extension assessment, to guide the treatment plan. We report a case of penile epidermoid carcinoma in a 54 year old uncircumcised man, with a history of chronic smoking, presenting with a mass in the base of the penis.

Retroperitoneal desmoid tumor in a patient with familial adenomatous polyposis: A case report.

Desmoid tumors are benign fibroblastic neoplasms, with locally invasive features and a tendency of recurrence. They are considered an aggressive non-metastatic fibromatosis. The retroperitoneal location is extremely rare. Their exact mechanism of occurrence is still controversial, but could be related to a genetic predisposition, hormonal factors or traumatic factors, including surgery. This entity faces management difficulties due to its rarity, the variable circumstances of its discovery, and the non-specific clinical manifestations. Their sensitivity to chemotherapy and radiotherapy is limited and surgery remains the only curative treatment in symptomatic cases, however observational waiting could consist the most appropriate management in selected asymptomatic patients, moreover it could avoid unnecessary morbidity from surgery or radiotherapy, which makes the management of this condition a multidisciplinary decision and should be adapted to fit the patients individually. We report a case of a retroperitoneal desmoid tumor in a 31-year-old woman with a history of familial adenomatous polyposis, through which we will discuss this extremely rare neoplastic entity.

Cervical myelopathy involving os odontoideum with retro-odontoid cyst and atlanto-axial instability: A case report.

Os odontoideum is an unusual anatomic variant of the dens of C2 defined as an independent ossicle separated from the axis; the etiology is a topic of debate, with investigative studies supporting congenital and traumatic origins, clinical manifestations vary from asymptomatic forms, underlying C1-C2 instability to compression of the spinal cord or vertebrobasilar ischemia. We report a case of a patient with a history of minor trauma 5 years ago, she suffered from neck pain. The clinical examination was normal. Radiological examination including X-ray, CT, and MRI showed cervical myelopathy involving os odontoideum with C1-C2 instability and compressive retro-odontoid cyst. Imaging has an important role in the management of os odontoideum, from diagnosis to therapy.

Presacral ganglioneuroma in an 8-year-old child: case report, and literature review.

Ganglioneuromas are benign tumors of the sympathetic nervous system, rarely found in the presacral region. In this study, we report the case of presacral ganglioneuroma in an 8-year-old girl, who complained of abdominal pain with diarrhea and abdominal distension. Ultrasound showed a large hypoechoic pelvic mass complicated by right ureter hydronephrosis. the CT and MRI confirm the presence of a presacral tissue mass with heterogeneous enhancement after contrast injection. The child underwent a complete surgical resection, and the anatomopathological study returned in favor of a ganglioneuroma. The presacral ganglioneuroma is an extremely rare tumor in that only twenty cases have been reported in the literature. 3 of which were less than 8-years-old. Through our case, we will review the epidemiological, clinical, radiological and therapeutic characteristics of this type of tumor.

Diaphragmatic hernia a rare cause of acute pancreatitis: Case report.

Many complications are known to occur in association with a diaphragmatic hernia. Acute pancreatitis occurring in this situation is very rare. In this paper, we report a case and describe the radiographic features of this complication. We report an unusual case of acute pancreatitis complicating a neglected post-traumatic diaphragmatic hernia in a 30-year-old male. This patient had a history of an abdominal trauma 5 years ago, and arrived at the emergency room with epigastria and left chest pain and vomiting. Serum lipase was elevated. Acute pancreatitis could be considered as an exceptional complication of diaphragmatic hernia. It is a serious diagnostic and therapeutic challenge. The fundamental roles of CT are to determine the diaphragmatic defect, the abdominal content involving, the Balthazar scoring of pancreatitis, and the presence of local complications. Even if a conservative approach is preferred when facing a diagnosis of pancreatitis, timing of surgery should be carefully considered.

Imaging appearance of isolated diffuse neurofibroma of nipple areolar area: a case report.

Sporadic neurofibromas of the nipple-areolar complexes are exceptional even in patients with neurofibromatosis. Diffuse neurofibroma is an uncommon subtype of neurofibroma that has received little attention in the imaging literature. As are most superficial lesions, it is often evaluated clinically and if biopsy is needed, it is usually performed without imaging. However the imaging data is quite characteristic with the aim of evaluating the extension in depth and detecting an underlying cancer. We report a case of women without a history of neurofibromatosis presenting a skin thickening disfiguring her left breast, related to diffuse neurofibroma of the nipple-areolar complexes confirmed histologically. We study echo-mammography and breast magnetic resonance imaging (MRI) findings in order to highlight its radiographics features.

Pancreatic schwannoma- CT and MRI findings: A rare case report and review of literature.

INTRODUCTION: Pancreatic schwannoma (PS) is an extremely rare benign tumor. Here we describe the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) results of PS in a 59 years old woman, as well as a review of the literature. CASE PRESENTATION: A 59-year-old woman consulted for atypical epigastralgia without fatigue, weight loss or fever. CT scan and MRI showed a 35 mm inhomogeneous lesion with well-defined margins located in the pancreas head. The diagnosis of pancreatic tumor was made. The pathologic examination of the biopsied mass yielded a diagnosis of pancreatic schwannoma. CLINICAL DISCUSSION: On CT scans, almost all benign PS are well-defined cystic or low-density masses. MRI is helpful in characterizing their typical encapsulation. CONCLUSION: The detection of pancreatic schwannoma is extremely rare. Although multiple imaging modalities are currently available, it is challenging to make an accurate diagnosis before operation.
