RESUMEN

Transrectal ultrasound (TRUS)-guided systematic biopsy, the current gold standard for the detection of prostate cancer, suffersfrom low sensitivity for clinically significant cancer. The use of diagnostic multiparametric MRI has increased the relevanceof targeted biopsy techniques such as MRI-TRUS fusion biopsy and direct (in-bore) MRI-guided biopsy, which have higherdetection rate for clinically significant cancer. Although primarily used in patients who remain at high clinical suspicion forprostate cancer despite a negative systematic biopsy, with the increasing use of upfront diagnostic MRI, these biopsies areexpected to replace routine systematic biopsies. This pictorial essay aims to enhance our understanding of the concepts ofthese biopsy techniques so that they can be performed safely and provide maximum diagnostic yield.

RESUMEN

OBJECTIVE: The inability to propel a bolus of food successfully from the posterior part of the oral cavity to the oropharynx is defined as transfer dysphagia. The present case series describes the varied presentation of transfer dysphagia due to focal dystonia and highlights the importance of early detection by following up on strong suspicions. METHODS: We describe seven cases of transfer dysphagia due to focal dystonia. Transfer dysphagia as a form of focal dystonia may appear as the sole presenting complaint or may present with other forms of focal dystonia. RESULTS: Four out of seven patients had pure transfer dysphagia and had previously been treated for functional dysphagia. A high index of suspicion, barium swallow including videofluoroscopy, associated dystonia in other parts of the body and response to drug therapy with trihexyphenidyl/tetrabenazine helped to confirm the diagnosis. CONCLUSION: Awareness of these clinical presentations among neurologists and non-neurologists can facilitate an early diagnosis and prevent unnecessary investigations.
