Dual- Energy CT (DECT) Pulmonary Angiography in Acute Pulmonary Thromboembolism (PTE): Causes, Semiology and Potential Diagnostic Pitfalls
ObjectivesThe dual-energy computed tomographic (DECT) technique allows the differentiation of materials with large atomic numbers such as iodine. The basic principle of dual-energy CT is material decomposition based on attenuation differences at different energy levels. The parameters for iodine extraction are a minimum value of – 960 HU, and a maximum of –600 HU. Lung parenchyma with normal perfusion in this attenuation range is presented in orange, and an area of decreased perfusion is visualized as an iodine defect area.
Carotid Body Tumor - Case Report and Review of the Literature
The paraganglioma of the carotid sinus is a relatively rare tumor, which represents the majority of paraganglioma of the head and neck (60-70%).
Association between Delay in Surgical Treatment and Perforation in Acute Appendicitis
Acute appendicitis is a prevalent emergency surgical pathology and without prompt intervention may lead to gangrene, perforation and death. Increased mortality and morbidity will increase the hospital stay and the costs. We aimed to see the association between surgical treatment and perforation.
A Severe Intracranial and Extracranial Complications of The Middle Ear Cholesteatoma (A Report Case)
Otological intracranial and extracranial complications are still a major problem and a life-threatening complication of otitis media mainly cholesteatoma. We present a case of a 40-year-old man, who presented mastoiditis with large subperiosteal abscess, repeated headache and acutely altered mental status, caused by subdural abscess. CT scan was done first to confirm the diagnosis, secondly to monitor the evolution.
Appendicitis in Pregnancy: How Vestigial is this?
Appendicitis is a rare pregnancy associated surgical emergency, with appendectomy as the most frequent non obstetrical surgical procedure performed in pregnancy. Diagnostic delay increases maternal and fetal morbidity and mortality thereby highlighting the need for a prompt diagnosis and surgery. Two cases of appendicitis with pregnancy are being reported with abdominal pain as common presenting feature.
Unusual Large Ethmoidal Osteoma with Orbital Extension
Large osteomas of the fronto-ethmoidal cavities are very rare benign tumors. Headache and ocular signs are the most common symptoms. Imaging allows the diagnosis. Treatment of ethmoid sinus osteoma is surgical. One case with orbital extension is reported and discussed. A 30 years-old male; complaining of swelling of themedial angle of the right eye. Computed tomography showed a right ethmoidal process with orbital extension. The tumor was removed through an external ethmoidectomy.
Olfactory Neuroblastoma (Esthesioneuroblastoma) following Retro-Orbital Irradiation for Graves’ Ophthalmopathy
We describe a case of radiation-induced olfactory neuroblastoma in a patient with a history of radiation for Graves’ ophthalmopathy. We also reviewed the literature and found four other cases of radiation-induced olfactory neuroblastoma reported since 2000, suggesting prior radiotherapy as one risk factor for this disease.
