Clinical imaging
-
To evaluate the contribution of transoral ultrasonography (TUS) in the diagnosis and treatment of peritonsillar abscess. ⋯ TUS allows the differentiation of peritonsillar abscess from cellulitis, hence to avoid an unnecessary invasive procedure in the case of a peritonsillar cellulitis.

Scedosporium apiospermum is a deadly fungal infection that can infect the central nervous system, particularly in immunocompromised patients. We present two cases of Scedosporium brain abscesses. ⋯ In the second case, the patient recovered and conventional MR findings are followed over several months. In the appropriate clinical setting, conventional MR imaging and MR spectroscopy may facilitate diagnosis, earlier initiation of antifungal pharmacotherapy and surgical intervention in this frequently fatal infection.

Case Reports
Embolic infarct presented with bilateral thalamic lesions possibly initiated by an emboli to the artery of Percheron.
Bilateral thalamic infarcts are rare and present with varying symptoms. Cardioembolism and small artery disease are the most common etiologic factors. The occlusion of a rare arterial variant called the artery of Percheron results in bilateral thalamic infarcts. Herein, we present the imaging findings of an embolic infarct starting from bilateral thalami, probably due to an emboli to the artery of Percheron first.

Case Reports
Osteoporotic vertebral compression fractures: a rare complication of radiotherapy in a patient with lung cancer.
The development of bone fractures after radiotherapy is a rare event which mainly concerns the pelvis or the long bones. This complication is unusual in the vertebrae. We describe the case of a 66-year-old male patient with lung cancer who was treated with combined radio-chemotherapy and developed dorsal pain secondary to vertebral compression 4 months after the end of radiotherapy. ⋯ Metastatic bone involvement is common in patients with lung cancer. When images are not typical of secondary progression, however, and there is no change in the general state of the patient, evidence of thoracic progression of the tumour or distal progression other than bone, vertebral osteoporotic complications should be considered. It is important that a wrong diagnosis is not made without histological proof of metastasis which has a poor prognosis.

We present a case of paradoxical air embolism (PAE) in the distal right coronary artery identified by coronary CT angiography. The underlying cause of PAE in the distal right coronary artery was a patent foramen ovale because the typical CT findings of a patent foramen ovale (i.e., combination of findings of the presence of a slit-like contrast column in the interatrial septum and a contrast jet through the septum) were identified by coronary CT angiography.
