A ruptured renal lymphangiectasia in the retroperitoneum: A rare complication of a rare condition.

Renal lymphangiectasia is a rare and benign renal lymphatics disorder. It is usually asymptomatic, and rarely revealed by lumbar pain, arterial hypertension or retroperitoneal fluid collection. Radiological diagnostic is challenging and can be done if radiologists are aware of the imaging findings. Here in, we report a case of a young woman admitted for the management of a blunt abdominal trauma. Computed tomography showed a huge right retroperitoneal fluid collection, communicating with a perirenal cyst. This perirenal collection was bilateral and symmetrical. The diagnostic of a ruptured perirenal lymphangiectasia was suspected and confirmed by needle puncture. We managed the case using percutaneous drainage. Reassessment at subsequent follow-up visits showed a total regression of the collection improvement in the patient's clinical.

Budd-Chiari syndrome secondary to retro-hepatic vena cava web: An unusual cause of epigastric pain.

Epigastric abdominal pain is a common indication for consultation. In the majority of cases, medical history, clinical examination and routine biological exams allow for an easy diagnosis. Sometimes the symptomatology is unusual, in which case it is essential to perform a complete clinical examination and to use various imaging techniques to search for eventual atypical causes. Membranous obstruction of inferior vena cava is a rare cause of such a phenomenon. We describe a Budd-Chiari syndrome caused by membranous obstruction of inferior vena cava in a 66-year-old woman with no medical history as a rare cause of epigastric abdominal pain. We will describe this clinical experience in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Pleural thymoma: A rare cause of pleural mass. About one case.

Thymoma is a rare tumor arising from the epithelium of the thymus gland and is usually located in the anterior mediastinum. Ectopic thymoma is very rare and can be located in the neck, trachea, lung, and pleura. Through this manuscript, we report a rare case of a 50-year-old woman presenting with dyspnea and recurrent pleural effusion. Her computed tomography of the thorax showed a unilateral left pleural mass. Biopsy of the pleural mass confirmed the diagnosis of pleural thymoma and she was started on chemotherapy. To our knowledge, this is the first reported pleural thymoma in our region.

Spinal cord infarction complicating acute aortic syndrome: about 2 cases.

Spinal cord infarction is an uncommon but devastating disorder caused by various conditions. It remains however a rare neurological complication in acute aortic injuries. In this context, aortic dissection is the most frequent etiological factor. Acute aortic intra mural hematoma and atheromatous penetrating ulcer remain exceptional. We encountered two cases of spinal cord infarction associated with acute aortic intra mural hematoma in one case and atheromatous penetrating ulcer in the other case that presented without typical severe pain. Thus, acute aortic injuries should be considered a cause of spinal cord infarction even if there is little or no pain.

Left-sided appendicitis revealing a common mesentery: A Case Report.

Intestinal malrotation is a congenital rotational anomaly that results of abnormal rotation of the gut, said to occur in 1 in 6000 live births. Common mesentery predisposes to volvulus of the midgut and internal hernias due to the left position of the cecum and appendix. The association of this anomaly with acute left appendicitis is rarely reported in the literature. Occurrence of acute appendicitis on common mesentery is a source of diagnosis difficulties, which may lead to a surgical management delay. We report a case of a 10-year-old boy, admitted for a left-sided iliac pain whose radiological investigations confirmed a left acute appendicitis associated with complete common mesentery. The child underwent laparoscopic surgery with simple post-operative follow-up.

Hemimelic epiphyseal dysplasia: a case report.

Hemimelic epiphyseal dysplasia HED also known as Trevor's disease is a rare pathology, characterized by a developmental disorder of an internal or external half of one or more epiphyses of a limb, mainly the lower limb, and/or of the short tarsal bones in children and young adolescents, with a male predominance. Its etiology remains unclear. Its clinical symptomatology is variable, ranging from asymptomatic involvement to orthopedic complications such as limb length inequality. As the clinic is non-specific, radiological assessment is the essential diagnostic tool for Trevor's disease, including standard radiography, MRI, CT, and possibly biopsy in some cases. The radio clinical signs make it possible to establish the diagnosis, even if it remains difficult because of the rarity of the disease and the presence of multiple differential diagnoses which are often better known such as osteochondroma and exostosis. After diagnostic confirmation, the therapeutic decision remains debated, ranging from simple observation to surgical excision. The prognosis of HED remains good, given the absence of the risk of malignant transformation. Post-therapeutic complications are dominated by recurrence or the appearance of secondary osteoarthritis. Objective: This clinical case challenges us to keep in mind the hemimelic epiphyseal dysplasia (HED) in front of a mass that originates at the level of the internal or external half of one or more epiphyses in children.

Sigmoid lipoma as an exceptional cause of intussusception and bowel obstruction in adults: A case report and review of literature.

Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.

Small bowel carcinoid tumor causing intestinal ischemia: A case report with review of the literature.

Background: Intestinal carcinoid tumors are well-differentiated neuroendocrine tumors that are capable of secreting bioactive hormones and/or amines; These tumors are uncommon but are the most common primary tumors of the small intestine. Case presentation: We report the case of an 80-year-old woman who presented with a long history (about 14 years ago) of atypical digestive symptoms such as vague abdominal pain, alternating diarrhea, and constipation, treated as functional colopathy without improvement, until the day when she presented with worsening pain that prompted her consultation. CT scan revealed typical manifestations of a carcinoid tumor associated with signs of subacute small bowel ischemia. Despite the surgery being considered a gold standard treatment, it was rejected due to the extent of tumor mesenteric involvement, therefore, the patient received only somatostatin treatment. Conclusion: Small bowel carcinoid tumors are rare, with typical imaging features based on cross-sectional imaging (CE CT/MRI). Intestinal ischemia is a well-known complication that can be a factor in mortality.

A rare case of sphenoid giant cell tumor: Case report & review of imaging features post short-term denosumab treatment.

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

Early hepatocellular carcinoma developed within dysplastic nodule as nodule-within-nodule appearance: Case report with literature review.

Close follow-up of patients with liver cirrhosis has led to increased detection of hepatocellular carcinoma (HCC) at an early stage, especially with magnetic resonance imaging (MRI) innovations. We report the case of a 70-year-old man, with a recent history of liver cirrhosis due to chronic hepatitis C virus (HCV) complicated by hepatocellular carcinoma (HCC), and for whom trans-arterial chemoembolization (TACE) was planned, as the patient was assigned Child B7 at admission. Angiography performed during the first TACE cycle shows not only the "tumor blush" corresponding to previously detected HCC but also an additional small foci of HCC uptake seen within a large dysplastic nodule giving the appearance of "nodule-within-nodule." Early detection of hepatocellular carcinoma improves prognosis. Hence, it is essential to be aware of all early aspects of HCC, including the nodule-within-nodule appearance on cross-sectional imaging, and also in angiography, as in this case.

Optic nerve tuberculoma in an immunocompetent patient: Case report.

Optic nerve tuberculoma is a rare extra-pulmonary manifestation of mycobacterial infection. It is usually associated with HIV infected patients. Due to its clinical polymorphism, the diagnosis and management of the disease either in immunocompetent patients and immunocompromised ones remains challenging. Herein, we discuss a case of a 32-year-old patient with no history of immunodeficiency admitted for multifocal tuberculosis with a reduced visual acuity as an extra-pulmonary manifestation, and radiologically revealed the presence of tuberculoma in the optic nerve in the cerebral MRI.

Unusual cause of binocular diplopia: Cavernous sinus hemangioma.

Cavernous hemangiomas are rare account representing 5%-13% of the intracranial vascular malformations and occur in approximately 0.5%-1% of the population. We report the case of 34-years-old woman, having a medical history of seizure, admitted for headache with binocular diplopia. The radiology investigation and operatory piece has shown an association of cavernous sinus hemangioma and frontal focal cortical dysplasia. This study highlights clinical, radiological and therapeutic features of this entity.

Atypical esophageal granular cell tumor: Case report.

Esophageal granular cell tumors (GCTs), or also called Abrikossoff's tumor are rare benign tumors originating from Schwann cells most commonly found in the skin, subcutaneous tissue, and tongue. Approximately 5% -8% arise in the gastrointestinal tract, and one-third of these tumors arise in the esophagus [1]. This neoplasm has a benign behavior usually, but there have been described a malignant transformation in 2% -3% of the cases. Herein, we discuss a case of a 70-year-old male patient with no pathological background, admitted for dysphagia evolving in 3 months that was explored with endoscopy and CT, the diagnosis at this level was challenging but the histopathology and Immunohistochemistry confirmed the presence of granular cells thus confirm the diagnosis. The purpose of our work is to report the uncommon evolution of an Abrikossoff 's tumor located in the esophagus, as a warning of the possible malignant transformation of this tumor mostly benign; also we made a review of the literature.

[Sturge-Weber-Krabbe Syndrome: an uncommon disorder (about a case)]. / Syndrome de Sturge Weber Krabbe: entité exceptionnelle (à propos d'un cas).

We report a case of Sturge-Weber-Krabbe Syndrome diagnosed in the Department of Radiology at the Hassan II University Hospital in Fes. This study highlights the clinical diagnostic and therapeutic features as well as the evolutionary characteristics of this uncommon neuroradiologic disorder.

[Rare localization of lipoma in the parotid region: about a case]. / Une localisation rare du lipome au niveau parotidien: à propos d'un cas.

Lipomas localization in the parotid region is very rare. We here report a new case of a 55-year old patient, presenting with a mass in the parotid region that had progressed over the past 4 years and a literature review. A soft, mobile and painless mass was detected on palpation. The patient underwent imaging examinations (ultrasound and MRI), that enabled to retain the diagnosis of parotid lipoma. The patient decided to have conservative treatment.
