High grade Burkitt lymphoma in an immunocompetent young patient: Concomitant gastric and ileal localizations.

Burkitt lymphoma is a highly aggressive and rapidly growing B cell non-Hodgkin lymphoma with heterogeneous pattern of manifestations. We present a rare case of a 39-year-old immunocompetent male with double localization of Burkitt lymphoma: gastroduodenal and ileal tract. The gastric location is extremely rare, and the association with another site is unusual with only few reports in the literature. Imaging modalities play a crucial role in correct diagnosis as it can manifest as a focal mass or as segmental wall thickening. Radiologists should recognize common and uncommon presentations and sites of Burkitt lymphoma given the urgency of potential treatment, in order to improve the patient's prognosis.

Zinner syndrome: A rare congenital cause of infertility.

Zinner syndrome is a rare congenital malformation characterized by cystic seminal vesicles and ejaculatory duct obstruction in association with ipsilateral renal agenesis. It appears to be frequently linked to infertility. However, recent advances in imaging, notably MRI, have led to an increase in the diagnosis of this pathology. We describe the case of a 39-year-old patient receiving examination for primary infertility who was identified with Zinner syndrome using ultrasound, CT, and MRI; the patient did not report hemospermia, lower urinary tract symptoms, or perineal pain. Examining the abdomen and external genitalia revealed no abnormalities, and examining the rectal area revealed none at all. Zinner syndrome is a rare congenital condition; we report this case to highlight the etiopathogenesis of this seminal anomaly, its relationship with renal dysgenesis, and to illustrate the imaging of this condition through various diagnostic methods.

Congenital bilateral perislyvian syndrome: A rare case report.

Congenital bilateral perisylvian syndrome, also known as bilateral periopercular syndrome or perisylvian polymicrogyria, is an exceptionally rare neurological disorder characterized by homogeneous clinicoradiological symptoms. There are consequently wide spectrums of clinical manifestations. In perisylvian syndrome. MRI is the preferred imaging technique. We describe the case of a female 8-year-old child who has a history of generalized tonic-clonic seizures. and was identified to have bilateral perisylvian syndrome based on MR imaging findings.

Bickerstaff brainstem encephalitis: A case report.

Bickerstaff brainstem encephalitis (BBE) is a rare inflammatory, demyelinating disease that generally has a good prognosis. It's characterized by an acute dysfunction of brainstem occurring few days after an infection. We report the case of an 11-year-old male child with a history of cold, presented with ataxia in whom a Bickerstaff encephalitis was attested through brain MRI and who has fully recovered after treatment. The main symptoms are ataxia, ophthalmoplegia, and altered consciousness. CSF analysis and serum antiganglioside antibodies are also very suggestive of the diagnosis that can be suspected clinically and confirmed on brain MRI. The interest of this observation lies in its rarity and on the rapid and spectacular clinical improvement under treatment.

Unruptured aneurysm with intramural thrombus is an unusual cause of spinal cord infarction: a case report.

Infarction of the spinal cord is a rather rare occurrence. Paraparesis or quadriparesis with vibration and proprioceptive senses sparing are symptoms of anterior cord syndrome. Ischemic anterior cord syndrome can result from an obstruction of the anterior spinal artery or the Adamkiewicz Artery. Spinal infarction due to abdominal aortic aneurysm with intramural thrombosis is an extremely rare condition, because of its rarity, it presents a diagnostic difficulty to clinicians, which may result in an inaccurate or delayed diagnosis. We present a case of spontaneous spinal cord infarction due to a previously asymptomatic aortic aneurysm with intraluminal thrombus, with a review of the literature.

[Mayer-Rokitansky-Küster-Hauser syndrome: a cause of primary amenorrhea: about a case]. / Le syndrome de Mayer-Rokitansky-Küster-Hauser comme cause d'aménorrhée primaire: à propos d'un cas.

Mayer-Rokitansky -Küster -Hauser syndrome (MRKH) is a rare cause of primary amenorrhea. It is defined as congenital aplasia of the uterus and of the upper two thirds of the vagina in women with normal development of secondary sexual characteristics. Diagnosis is essentially based on magnetic resonance imaging (MRI). We here report the case of a 17-year-old girl presenting with primary amenorrhea with well developed secondary sexual characteristics. Laboratory tests revealed normal ovarian function as well as gonadotropic axis. Pelvic ultrasonography and magnetic resonance imaging revealed complete uterine agenesis of the uterus, the upper two-thirds of the vagina and left kidney, allowing to confirm the diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome type II. This study highlights the importance of suspecting MRKH in young patients with well-developed sexual characteristics and any type of primary amenorrhea as well as of performing MRI in order to detect any specific sign of this disorder.

Dural ectasia: a manifestation of type 1 neurofibromatosis.

Dural ectasia denotes circumferential expansion or dilatation of the dural sac, and has been frequently reported in association with type 1 neurofibromatosis (NF1). The pathogenesis has not been defined, but its correlation with NF1 infers a congenital malformative hypothesis. The neural elements in the dilated sleeve typically are not enlarged or abnormal, nevertheless the enlarged area contain an increased amount of cerebrospinal fluid. The dura in the area of ectasia is extremely thin and fragile, and erodes the surrounding bony structures destabilising the spine and permitting spectacular spinal deformities. We present a case: a 40-year-old woman suffering from neurofibromatosis type 1 who developed a thoracic dural ectasia and anterior meningocele.

Dual intersection syndrome of the forearm: a case report.

The intersection syndrome, described since the 19(th) century, is an uncommon disorder associated with rubbing at the crossing point between the first dorsal compartment muscles and the radial wrist extensor muscles. Imaging modalities used to diagnosis this syndrome includes ultrasonography and magnetic resonance imaging. We reported a case of a 60-year-old man presented to our formation with painful swelling on the dorsum of the wrist and forearm. An MRI and an ultrasound were performed, and objectified a dual cross syndrome of the forearm.

Adenocarcinoma arising from chronic perianal crohn's disease: a case report.

Malignant transformation of perineal fistula in Crohn's disease has rarely been reported. We report a case of Crohn's disease with recurrent perineal fistulas. A 36-year-old male, diagnosed with Crohn's disease at the age of 24, developed adenocarcinoma in an anorectal fistula that had existed for years. He was treated with adjuvant chemoradiotherapy but died. A high index of suspicion and regular surveillance is recommended in chronic anorectal fistulas in Crohn's disease. The shorter duration of Crohn's fistulas prior to malignant degeneration necessitates an aggressive approach to rule out cancer.
