[Septo optic dysplasia plus: about a case]. / Dysplasie septo optique plus: à propos d'un cas.

Septo optic dysplasia plus is a rare disease seen in children. Its diagnosis is radiological, based on brain magnetic resonance imaging (MRI). We report the case of a child aged 2 years and 4 months, with no particular pathological history; who consulted for psychomotor retardation, strabismus and low vision behavior. An endocrine biological assessment exploring the hypothalomo-pituitary function was carried out, revealing no abnormality. The diagnosis of septo-optic dysplasia plus was retained on the brain MRI data, in front of the agenesis of the septum pellucidum and of the splenium of the corpus callosum, the hypoplasia of the optic pathways and of the pituitary stalk as well as in front of the agenesis of the posterior pituitary. It was associated with a closed schizencephaly. Septo-optic dysplasia is a rare congenital malformation. Our objective is to recall its semiology in imaging and to underline the importance of MRI to establish the diagnosis. Septo-optic dysplasia is a rare clinical entity typically involving midline brain abnormalities, optic nerve hypoplasia, and pituitary insufficiency. The association with cortical malformations such as schizencephaly and polymicrogyria denotes the term septo-optic dysplasia plus. Advances in imaging currently allow early diagnosis, which is essential for adequate management. Antenatal ultrasound may suspect dysplasia, and brain MRI confirms the diagnosis.

Splenic volvulus on ectopic spleen in adults: A case report.

Ectopic spleen is a rare clinical entity characterized by splenic hypermobility which may be congenital or acquired. The spleen may be migrated to different positions in the peritoneum. The main complication is pedicular torsion with splenic volvulus, presenting as an emergency abdominal surgery. We present and discuss a case of ectopic and twisted spleen resulting in complete splenic infarction, diagnosed by ultrasound, confirmed by CT scan and treated by splenectomy.

Spontaneous splenic rupture during infection of cytomegalovirus. A case report.

Splenic rupture is most commonly encountered after blunt abdominal trauma. Spontaneous atraumatic splenic rupture is a rare but dramatic occurrence that is most commonly attributed to infection or neoplasia. We report the case of a 27-year-old female patient without pathological history. Admitted to the emergency department for the sudden onset of left hypochondrial pain associated with vomiting, rapidly progressing to hypovolemic shock. She had reported an influenza-like illness a week earlier for which her COVID-19 PCR was negative. Emergency abdominal ultrasound and CT-scan revealed a ruptured spleen and widespread hemorrhagic fluid in the abdomen. Exploration revealed multiple ruptures in the spleen capsule. The patient underwent splenectomy with good clinical evolution. Despite the rarity of this condition, physicians should consider the diagnosis of spontaneous non traumatic splenic rupture when encountering healthy patients presenting with nonspecific left hypochondrial abdominal pain and hypovolemia. Mortality is essentially related to the delay in diagnosis and treatment and to the severity of the underlying pathology. Treatment often consists of splenectomy.
