Susac syndrome is a rare microangiopathy of indeterminate etiology, presumably autoimmune, characterized by a triad of encephalopathy, sensorineural hearing loss, and branch retinal artery occlusions occurring predominantly in women. The onset and progression patterns are multiple, mainly of three modes. Fulminant evolution is exceptional, rarely reported across literature. We report through this case a Susac syndrome in a young man in whom evolution was fatal. Magnetic resonance imaging is essential to raise the diagnosis and for follow-up, with almost pathognomonic findings, all the more useful as the clinical triad is usually incomplete and as the encephalopathy is the most limiting of the symptoms.

60-year-old diabetic patient, followed for Hodgkin's lymphoma who presented to the emergency room for diffuse abdominal pain in a febrile context. The biological examination showed hyperleucocytosis with a high CRP (320mg/l). An ultrasound was performed showing a voluminous lateralized right pelvic collection confirmed by an abdominal CT scan. The patient benefited from a percutaneous drainage objectifying a purulent liquid. The cytobacteriological examination came back in favor of E.coli. The patient was put on ceftriaxone-based antibiotic therapy. Evolution is marked by a decrease in fever with persistence of high CRP. A CT scan showed a clear regression of the collection with the appearance of intraosseous air bubbles in the iliac wings without cortical involvement, suggesting emphysematous osteomyelitis.

Aceruloplasminemia is a rare autosomal recessive disorder of iron accumulation in the brain. It is one of the subtypes of Neurodegeneration with brain iron accumulation and is characterized by the uniform involvement of all basal ganglia, thalami, dentate nuclei, and cortex. Aceruloplasminemia is the only known iron overload disorder in which brain and systemic iron overload are combined. Here, we present a 53-year-old female who had progressive cognitive disorders with motor deficits. MRI showed extensive and abundant iron deposited in the brain and in the liver.

Chilaiditi's syndrome is a symptomatic hepato-diaphragmatic interposition of a colon and/or small intestine. When it is asymptomatic, it is called Chilaiditi's sign. It is a benign condition that may mimic other concerning diagnoses on radiography, such as diaphragmatic hernia or pneumoperitoneum. Computed tomography (CT) is the best imaging tool to assess the diagnosis. We report a rare case of Chilaiditi's syndrome with intermittent dyspnea, suspected on radiography and diagnosed on CT. Nasogastric decompression relieved the patient's symptoms.
