We report a case of a 39-year old woman who upon developing a rapidly enlarging posterior cervical space tumour, underwent incisional biopsy prior to diagnostic imaging that resulted in nearly catastrophic haemorrhage. Subsequently, MR imaging showed evidence of marked hypervascularity, prompting diagnostic angiography and endovascular microembolization prior to surgical resection. The tumour turned out to be a large haemangiopericytoma arising from the paravertebral musculature. The case is instructive by highlighting the need for considering rare locations of hypervascular tumours in the head and neck region before attempting biopsy, which can be predicted by cross-sectional imaging studies, and the benefits of pre-operative devascularization with modern superselective microembolisation techniques.

The purpose of this article is to illustrate the cross-sectional imaging appearance of postradiation changes and complications of radiotherapy in the head and neck. Radiotherapy is an important treatment modality for head and neck cancer, and is often used in conjunction with chemotherapy. Recognition of the varied effects of radiotherapy to the head and neck region is essential to correctly interpret posttreatment imaging and may help prevent further complication.

ABSTRACT Despite many years of dedicated research into the etiopathogenesis of adolescent idiopathic scoliosis, there is still no single distinct cause for this puzzling condition. In this overview, we attempt to link knowledge on the complex three-dimensional pathoanatomy of AIS, based on our ongoing research in this field, with etiopathogenic questions. Evidence from multiple recent cross-sectional imaging studies is provided that supports the hypothesis that AIS has an intrinsic biomechanical basis: an imbalance between the biomechanical loading of the upright human spine due to its unique sagittal configuration on the one hand, and the body’s compensating mechanisms on the other. The question that remains in the etiology of AIS, and the focus of our ongoing research, is to determine what causes or induces this imbalance.

Abstract In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen.

AbstractRadiation therapy is the mainstay in the treatment of head and neck cancers, in addition to surgery and chemotherapy. Expected radiotherapy changes evolving over time may be confused with recurrent tumor. Conversely, even residual or recurrent tumor in the setting of postradiotherapy changes may be difficult to identify clinically or even by radiological imaging. Therefore, it is important to be familiar with the temporal evolution of these changes. The purpose of this pictorial essay is thus to illustrate distinctly the expected radiotherapy changes and radiotherapy-related complications in the head and neck region and to differentiate them from tumor recurrence on routine cross-sectional imaging techniques (computed tomography and magnetic resonance imaging).

Transperineal sonography is a diagnostic tool for imaging the pelvic floor and lower pelvis. Because of the higher spatial resolution of pelvic sonography compared with other cross-sectional imaging techniques, transperineal sonography can provide detailed visualization of the lower pelvic organs, including the urethra, vagina, and anorectum. This case report describes the use of transperineal sonography for evaluation of an indeterminate lower pelvic process seen on computed tomography in a 53-year-old woman with progressive pelvic pain, dysuria, and dyspareunia. Because of severe dyspareunia, the patient declined transvaginal sonography. Transperineal sonography provided diagnostic imaging of the anal mass causing these symptoms.
