RESUMO
Lemierre's syndrome is a rare, life-threatening condition, which may be fatal if not properly treated. This disease refers to thrombophlebitis of the internal jugular vein, which is the result of bacterial sore throat infection (usually in the form of pharyngitis) that extends into the parapharyngeal space. However, it can result from other infective foci in the ear, nose, parotid glands, and paranasal sinuses. The bacteria typically responsible is Fusobacterium necrophorum. Here, we describe a case of Lemierre's syndrome that occurred in a 20-year-old female who presented with neurological deficits following a two-week history of upper respiratory tract infection. Our case displayed typical findings of this rare condition with a review of the previous literature and also to emphasize the importance of high index of suspicion to reduce the mortality of this disease.
RESUMO
Dermatofibrosarcoma protuberans (DFSP) is a rare soft tumor which originally represents a cutaneous sarcoma. It grows slowly and presents usually as nodular superficial lesion on the trunk or the extremities. Although these tumors are locally aggressive with high rate of recurrence following surgery; the prognosis is considered excellent when it is effectively treated. The radiological appearance of this tumor has rarely been studied and findings infrequently discussed in the literature probably because many lesions underwent resection before imaging. Although imaging is infrequently performed for this lesion; it can show characteristic features and demonstrate the full extent. Imaging may also play a role in the differentiation of this tumor from more serious soft tissue lesions such as more aggressive sarcomas and hemangioma. In this article, we discuss the imaging findings of DFSP that can aid in its diagnosis and its variable appearances. In addition; the clinical presentation and treatment options are also described with review of the previous literature.
