    Notes: Abstract  Objective. To compare information gained by ultrasonography and magnetic resonance imaging (MRI) in chronic achilles tendinopathy with regard to the nature and severity of the lesion. Design. Imaging of both achilles tendons with ultrasonography and MRI was performed prior to unilateral surgery. Operative findings and histological biopsies together served as a reference. Patients. Twenty-seven patients (22 men, 5 women; mean age 44 years; 21 athletes) suffering from chronic achilles tendinopathy participated in the study. Eighteen patients had unilateral and 9 had bilateral symptoms. Results and conclusions. Surgical findings included 4 partial ruptures, 21 degenerative lesions and 2 macroscopically normal cases. Microscopy revealed tendinosis (degeneration) in all tendon biopsies, including cases with a partial rupture, but only slight changes in the paratendinous tissues (paratenon). Ultrasonography was positive in 21 of 26 and MRI in 26 of 27 cases. Severe intratendinous abnormalities and a sagittal tendon diameter 〉10 mm suggested a partial rupture. In tendons with a false negative result histopathological changes were mild and a tendency towards a better clinical outcome was noted in the sonographic cases. Assessment of the paratenon was unreliable with both methods. Ultrasonography and MRI give similar information and may have their greatest potential as prognostic instruments.

    Notes: Abstract Pharyngeal constrictor paresis (PHCP) is sometimes found in videoradiography of the swallowing act in patients complaining of dysphagia. Ten patients with PHCP and 10 dysphagic, age- and sex-matched controls with normal videoradiography were neurologically evaluated and examined with magnetic resonance imaging (MRI) of the brain and brainstem in order to learn the pathogenetic process behind PHCP. The study revealed 8 PHCP patients and 1 dysphagic control with abnormal clinical neurological findings such as myopathy, cerebrovascular disease, or extrapyramidal disease. The neurological examination revealed considerable information of prognostic and therapeutic value in PHCP patients. The MRI was abnormal in 7 PHCP patients and 4 dysphagic controls. However, the findings in MRI were nonspecific but the examination was found to be valuable in selected cases. It is concluded that PHCP is an indicator of neurological disease and accordingly, such patients should be examined by a neurologist to establish the cause of the disease.
