Emphysematous hepatitis is a rare entity characterized by the replacement of hepatic parenchyma by gas, leading to acute liver failure. Often it occurs in patients with diabetes mellitus, liver disease or a recent history of abdominal surgery. We present a case of emphysematous hepatitis in a 74-year-old man with no recognizable risk factors. Despite the early broad-spectrum antimicrobial therapy and supportive care, the condition progressed to a fatal outcome, as seen in other case reports. Early recognition of this condition and rapid and aggressive management may improve patient outcomes.

Cystic lymphangioma mainly occurs in children and develops from the lymphatic vessels. The present study reports the case of a 36-year-old female patient with a giant cystic mediastinal lymphangioma. She was asymptomatic and the diagnosis was accidental. Imaging studies are important for referral to the Cardio-Thoracic Surgery Department for surgical intervention in order to remove the lesion. It is important that in the case of an enlargement of the mediastinum observed in a thoracic X-ray, the possible diagnosis takes into consideration various hypotheses. Early diagnosis may prevent further growth and infiltration of structures that hinder the surgical approach.

Cerebellar ataxia implies changes in motor coordination and balance. An etiological study is difficult given the countless differential diagnoses. Autoimmune causes, namely due to anti-GAD antibodies, represent only around 2% of progressive cerebellar ataxia in adults [1]. The case presented is of a woman with a history of epilepsy and alopecia universalis that began to show a condition of cerebellar ataxia whose study revealed an autoimmune ataxia with positive Anti-GAD 65 antibodies. Therapeutics with intravenous immunoglobulin enabled partial improvement of the symptoms.
