Spontaneous Bilateral Carotid Artery Dissection: Diagnosis and Follow-up with MDCT. A Case Report.

Carotid artery dissection is usually unilateral. Rarely bilateral forms can be seen. Recent studies have shown the efficacy of computed tomography angiography (CTA) in the diagnosis of carotid dissection. Herein we report a case with bilateral carotid artery dissection diagnosis and follow-up which was carried out using mainly CTA.

Recurrent Cerebral Fat Embolism Due to Pleural Irrigation: Fat Density Lesions on CT. A Case Report.

Fat embolism syndrome is a rare, but life-threatening problem and is usually associated with severe trauma. Neurological symptoms are variable, and the clinical diagnosis is difficult. We describe a patient with fat density lesions on cranial CT sections and discuss the etiopathogenesis of cerebral fat embolism (CFE) in this patient who does not have a history of long bone fracture, but metastatic lung disease and empyema. This is probably the first case report of CFE secondary to pleural irrigation of empyema with demonstrative CT findings.
