Severe pulmonary hypertension associated with hypothyroidism and mixed aortic valve disease: A case report.

Pulmonary hypertension is a condition characterised by elevated pulmonary arterial pressures secondary to various aetiologies; the most common ones are left heart diseases. Similarly, an association between thyroid diseases and pulmonary hypertension has been reported in some cases, but the pathophysiological relationship has not been fully elucidated. Etiological investigation is an important step in the management of pulmonary hypertension and determines the appropriate treatment. In this report, we present a case of severe pulmonary hypertension in a 57-year-old woman, in which mixed aortic valve disease and hypothyroidism were involved.

Posterior Reversible Encephalopathy Syndrome: A Complication of Acute Renal Failure in a Child.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity occurring during several conditions and more frequently in those associated with severe hypertension. The diagnostic approach is possible by considering the clinical context and MRI data, where white matter abnormalities are observed predominantly in the parietal and occipital territories secondary to the formation of a vasogenic edema. The evolution is characterized by a reversibility of the lesions in case of early diagnosis and management. The authors report a case of reversible posterior encephalopathy in a 12-year-old child who presented with a status epilepticus, revealing an acute renal failure.

A spinal cord compression syndrome revealing neurofibromatosis type 1: A case report.

Neurofibromatosis type 1 (NF1), formerly known as von Recklinghausen disease is an autosomal dominant disease with multisystem involvement. In the peripheral nervous system, it leads to the development of benign tumors from the tissue of the spinal or cranial nerve sheaths, known as "neurofibromas." We report the case of a 40-year-old patient with spinal cord compression syndrome in whom spinal MRI revealed cervical, dorsal and lumbosacral neurofibromas revealing neurofibromatosis type 1.

Carotid canal fracture with internal carotid artery transection: A deadly trauma.

Carotid artery injuries are rare with an incidence of 1%-2.6% in trauma patients. They are associated with high morbi-mortality rates, with mortality ranging from 19% to 43%. The diagnosis relies mainly on computed tomography angiography in the emergency setting; however, it is fundamental to be able to suspect carotid artery injuries on non-contrast computed tomography, as the latter is the routine imaging tool for trauma patients. We report the case of a young male, victim of a blunt high velocity motor-vehicle trauma. He was unconscious, with abundant epistaxis and hypovolemic shock. A fracture of the left carotid canal on non-contrast computed tomography was seen, raising concern for an arterial injury. A computed tomography angiography was performed subsequently revealing a transection of the internal carotid artery. This type of injury is highly lethal, and its management relies on urgent surgical intervention, and endovascular treatment, with the purpose of controlling the hemorrhage.

Trichobezoar: A Rare Cause of Gastric Obstruction.

Trichobezoar is a rare disorder of the young girl with a psychiatric profile. It is suspected when there is a notion of trichophagia, although its clinical manifestations are non-specific. Imaging through CT scan, plays a fundamental role in the diagnosis of extensive forms.

Caudal Regression Syndroma: A Rare Cause of Chronic Constipation.

A malformative syndrome of the lower spine pole, caudal regression syndrome is a rare condition (1-5 cases/100 000 births). It usually occurs in children of diabetic mothers and includes a wide range of disorders. This case illustrates a subtype of this syndrome (type IV, group I) in a non-diabetic mother.

Bone Manifestations of Neurofibromatosis Type 1.

Von Recklinghausen disease is the most common phacomatosis. It can affect many systems, including the bone system. Through these 2 cases, we illustrate the bone manifestations of this disease.

Neurological Involvement Complicating Invasive Pulmonary Aspergillosis.

Cerebral aspergillosis is a fungal infection with a bad prognosis. It usually occurs in immunocompromised patients and manifests itself .Cross-sectional imaging reveals suggestive lesions.
