Large occipital nerve (Arnold’s nerve) schwannoma

A 37 year-old man who had a ten years history of remitting and intermittently severe neck pain with a suboccipital mass is presented. On initial neurological examination there was no abnormal finding except little mass in the posterior neck. Following physical examination radiological evaluation was requested. In sagittal pre (A) and postcontrast (B) T1W images the lesion in between cervical 2 and 3 spinal process (arrow). The lesion was well defined, encapsulated, heterogeneously enhanced in 2.5 x 2 cm size. There was no bony destruction but remodeling. On axial image the configuration and the location in the semispinalis capitis muscle was easily identified easily (C). The patient underwent operation and final pathologic and radiologic diagnosis was schwannoma with Antoni A cells which was originated from the greater occipital nerve

Multifocal skeletal tuberculosis involving the lumbar spine and a sacroiliac joint: MR imaging findings

PubMed ID: 16972219Sacroiliac joint tuberculosis is rare; its coexistence with vertebral tuberculosis is even rarer, with only a few such patients reported in the literature. We present magnetic resonance (MR) imaging findings of a patient with vertebral and sacroiliac joint tuberculosis, who had paravertebral, iliopsoas, and buttock abscesses accompanied by a gluteal pus-draining sinus tract. MR imaging is the most sensitive and specific imaging modality for diagnosing sacroiliitis at its early stage. Sacroiliac joint tuberculosis can reach advanced stages with extensive joint destruction and periarticular abscesses if diagnosis and treatment are delayed. A high index of clinical suspicion is required for an early diagnosis. The addition of a coronal SPIR T2-weighted sequence to the routine MR imaging evaluation of patients studied for lumbar disk disease may be useful for recognizing sacroiliac joint pathology at an earlier stage. © Turkish Society of Radiology 2006

Diffusion-weighted and conventional MR imaging in neurotrichinosis

WOS: 000228184400014PubMed ID: 15902897Central nervous system involvement in trichinosis is not rare. Brain lesions in trichinosis have been defined on computed tomography and magnetic resonance imaging (MRI) as multifocal small lesions located in the cerebral cortex and white matter. We present a case of trichinosis with multifocal lesions of the brain detected by MRI and diffusion weighted MRI. Evolutions of these lesions from acute through chronic stages on follow up studies are also presented. This is the first report describing sequential MRI findings and diffusion weighted imaging appearance of brain lesions in trichinosis. Sequential evaluation of conventional and diffusion MR data allowed us to conclude that multifocal lesions in the brain were related to multiple infarctions rather than true inflammatory infiltration of the brain parenchyma

Antenatally diagnosed neonatal craniopharyngioma.

PubMed ID: 8576765A case of neonatal craniopharyngioma diagnosed by fetal ultrasonography at 29 weeks and by magnetic imaging at 35 weeks of gestation is presented with clinical and neuroradiologic findings. This is a rare tumor and only 10 cases of neonatal craniopharyngioma have been previously reported
