MR-Diffusion characteristics of cerebral alveolar echinococcosis and its role in differentiating cerebral alveolar echinococcosis from metastases

role of magnetic resonance spectroscopy and susceptibility weighted imaging in cerebral alveolar echinococcosis.

background: to analyze the characteristic performance of magnetic resonance spectroscopy (mrs) and susceptibility weighted imaging (swi) in cerebral alve-olar echinococcosis (cae). methods: we retrospectively analyzed 10 clinical-identified cae cases mr per-formance, and summarized the mrs and swi performance of cae. results: the 10 cases of cae all had the history of primary hae, among who 6 c...

Alveolar echinococcosis of the liver: MR findings.

Nineteen cases of proven hepatic alveolar echinococcosis were examined by magnetic resonance (MR) and the results were compared with CT. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cysts. Central necrosis was more e...

Alveolar echinococcosis presenting with simultaneous cerebral and spinal involvement.

A 37-year-old Tibetan shepherdess presented with headache and weakness of the lower limbs for 10 months. Examination disclosed a positive straight-leg-raising test. Neuroimaging showed a heterogeneous mass in the left temporal lobe (figure 1) and an intradural mass in the lumbosacral canal with L4 vertebral body destruction (figure 2). Chest and abdominal CT scans were negative. Two operations ...

Primary cerebral alveolar echinococcosis: mycology to the rescue.

A case of primary cerebral alveolar echinococcosis with a favorable outcome is reported. A universal fungal PCR enabled this diagnosis, while the initial serological analysis remained noncontributive.
