Based on unmarkedness of coronal cross-linguistically, coronal has been considered to be underspecified. Also, place assimilation where coronal tends to assimilate to the adjacent labial or velar by a featurefilling rule has been support the underspecification of coronals. I instead argue that coronal should be specified in Optimality Theory despite its unmarkedness, and place assimilation no l...

Nasal dermal sinus is a rare congenital anomaly. We report a case of the dermal sinus associated with a dumbbell-shaped dermoid and demonstrate the detailed anatomy. The patient was a boy aged 1 year and 4 months with a small pit at his nasion from birth and developed swelling of the forehead. The sagittal view of a T2-weighted image demonstrated a dumbbell-shaped, mixed intense dermoid at the ...

PURPOSE To look for central nervous system abnormalities as possible causes of intractable hiccups. METHODS Of a series of 50 patients with chronic (ie, lasting more than 48 hours) hiccups, a prospective study identified a subgroup of 9 patients with no clinical or gastroesophageal abnormalities (according to endoscopy, pH monitoring and manometry). We performed in all 9 patients brain and up...

BMJ Case Reports Published online: 10 December 2012 doi:10.1136/bcr-2012007643 DESCRIPTION A 32-year-old man was referred to a radiology department for intermittent anterior knee pain and swelling for approximately 6 months. The patient denied any history of major trauma, fracture or infection. MRI was performed to diagnose the cause of knee pain. The ax...

Background and purpose: Radially oriented hypointense stripes in hyperintense cerebral white matter are recognized on T2-weighted images of certain lysosomal storage disorders. We compared in vivo and postmortem MR imaging findings with histopathologic findings in three patients with metachromatic leukodystrophy (MLD), globoid cell leukodystrophy (GLD) and infantile GM1 gangliosidosis (GM1) to ...

A 46 year old man presented with dull right shoulder pain irradiating to the right upper arm. Physical examination showed right glenohumeral instability. There was no muscle atrophy. Radiography and an echogram of the right shoulder were normal. An EMG showed fibrillation potentials and positive sharp waves in the right infraspinatus muscle; recruitment of motor units was reduced on maximal vol...

Meningiomas are the most common primary tumours of the canine central nervous system. The incidence of these tumours increases with age and they are more frequently encountered in dogs older than seven years. Meningiomas are solitary, well-defined neoplasias that more commonly grow via compression and less commonly by infiltrating the nervous tissue. Meningiomas exhibit 82% intracranial, 15% in...

We investigated the safety and clinical applicability of 7.0 Tesla (T) brain magnetic resonance imaging (MRI) in patients with brain tumors. Twenty-four patients with intraaxial or extraaxial brain tumors were enrolled in this study. 7.0T MRIs of T2*-weighted axial and T1-weighted coronal or sagittal images were obtained and compared with 1.5T brain MRIs. The T2*-weighted images from 7.0T brain...

BACKGROUND The mechanism of a progressive lacunar infarction is not well understood, and changes in ischemic tissue after onset have not yet been clarified clinically. OBJECTIVE To investigate the pathophysiological characteristics of a case of progressive lacunar infarction using diffusion-weighted and conventional magnetic resonance imaging (MRI) scans. PATIENT A 73-year-old woman was hos...

BACKGROUND AND PURPOSE Radially oriented hypointense stripes in hyperintense cerebral white matter are recognized on T2-weighted images of certain lysosomal storage disorders. We compared in vivo and postmortem MR imaging with histopathologic findings in three patients with metachromatic leukodystrophy (MLD), globoid cell leukodystrophy (GLD), and infantile GM1 gangliosidosis (GM1) to understan...
