    Balo's concentric sclerosis in a patient with spontaneous remission based on magnetic resonance imaging: A case report and review of literature
    (Baishideng Publishing Group Co, 2018) Ertuğrul, Özgür; Çiçekçi, Esra; Tuncer, Mehmet Cudi; Aluçlu, Mehmet Ufuk
    Balo's concentric sclerosis (BCS) is a rare monophasic demyelinating disease known as multiple sclerosis subtype and seen as a round lesion with variable hyper and hypodetoxification layers. Characteristic appearance can be seen as "bulb eye" or "onion bulb". The initial terminology for this neurological disorder was leukoencephalitis periaxialis concentrica; this is defined as a disease in which the white matter of the brain is destroyed in concentric layers in such a way as to leave the axial cylinders intact. This report presents a case of BCS with spontaneous healing of the patient and a mass lesion with concentric rings adjacent to the left lateral ventricle and the posterior portion of the corpus callosum with peripheral vasogenic edema. The neurological lesion of the patient was similar to the magnetic resonance imaging and clinical findings of the BCS.

    Spontaneous rupture of a hepatic hydatid cyst perforating into the gastric antrum diagnosed with magnetic resonance imaging a case report and review of the literature
    (SCI Printers & Publication INC, 2021) Ertuğrul, Özgür; Tuncer, Mehmet Cudi; Gedik, Ercan
    BACKGROUND: Hepatic hydatid disease is a parasitic zoonosis caused by Echinococcus granulosus. The liver is the most frequently parasitized organ in humans. E. granulosus typically forms a small, fibrous, edged cyst when there is any surrounding host reaction. Classically, there is a large parental cyst with a large number of peripheral daughter cysts. Satellite daughter cysts are common. E. granulosus has two forms: pastoral and sylvatic. CASE: A 36-year-old woman was hospitalized upon complaint of nonspecific, continuous, moderate-to-severe epigastric pain of 1 week's duration. There was no fever or vomiting. Only serum aspartate transaminase (420 U/L), alanine aminotransferase (180 U/L) (normal up to 50 U/L), and erythrocyte sedimentation rate (65 mm/hour) were increased in her laboratory findings. She had a hydatid cyst in the right lobe of the liver and refused all treatment protocols. Her magnetic resonance imaging and magnetic resonance cholangiopancreatography data showed a ruptured liver hydatid cyst associated with closed perforation in the antrum region of the stomach. CONCLUSION: Typically, locations of hepatic hydatid cyst can be seen into the biliary tree, peritoneal space, and blood stream, but extension outside of the liver is rarely seen in the literature.
