Abstract Chronic perineal pain is an often encountered problem that is difficult to evaluate. Based on a series of 17 patients in whom urological, gynecological, and anorectal pathology was excluded, the authors compared magnetic resonance imaging (MRI) with computed tomographic (CT) scan with myelography in the investigation of chronic perineal pain. After a clinical neurological examination, patients underwent radiodiagnostic imaging of both techniques. Thirteen patients (76%) had one or more sacral meningeal cysts (MC) on MRI scan, whereas CT scan with myelography of the lumbar and sacral region revealed 7 patients (41%) with sacral MC. Sacral MC may be the etiology of chronic perineal pain in many instances, and MRI scan appears to be superior to CT scan with myelography in demonstrating sacral MC. Ten patients with sacral MC were operated on with moderate to excellent results 6 months after operation. Early postoperative results are encouraging, but further follow-up and larger series are required.

Abstract Between 1987 and 1988, we utilized magnetic resonance imaging (MRI) in the diagnosis of seven cases of “subacute” pituitary apoplexy. that is, intra-adenomatous pituitary hemorrhage associated with clinical symptoms atypical of acute pituitary apoplexy. These symptoms lasted longer than 24 hours and included visual changes in four patients, headache in five, and seizures, endocrine dysfunction, and oculomotor palsy in one each. Estimates of the ages of the hemorrhages were also possible based on characteristics on the MRI scan and ranged from 48 hours to more than 14 days. Four of our seven patients underwent transsphenoidal decompression at which time the presence of intratumoral hemorrhage was confirmed. The remaining three patients have been followed as outpatients with serial MRI examinations and have shown improvement in clinical symptoms and stabilization of the radiological picture. From our series of patients, it is now apparent that the MRI scan is an invaluable tool in identifying this subacute form of intra-adenomatous pituitary hemorrhage and has proven especially useful as a means of therapeutic planning and follow-up care in patients presenting with symptoms not typical of classic pituitary apoplexy.

Tracheal metastasis from papillary thyroid carcinoma (PTC) is an unprecedented and rare entity. We present the case of a 65 year-old lady who suffered from dyspnea and a thyroid goiter that turned out to be PTC. A magnetic resonance imaging (MRI) scan of the lungs revealed a huge tracheal mass causing obstruction of the tracheal lumen. She underwent a surgical tracheostomy and diode laser debulking of the tumor. Following this, she had a total thyroidectomy and postoperative radioiodine ablation and radiotherapy. She remains well under close and regular follow-up. A secondary tracheal tumor usually comes from a lymphatic spread of the primary tumor, whereas the vascular route is rarely reported. Endoscopic minimally invasive laser tracheal surgery with adjuvant radiotherapy appears to be equally effective to more aggressive tracheal resections.

Absent Septum Pellucidum

Improved fetal imaging has resulted in increased diagnosis of isolated absent septum pellucidum without other intracranial abnormalities. There is little literature regarding outcomes for these fetuses. This study hypothesized the majority of infants diagnosed by fetal magnetic resonance imaging (MRI) with isolated absent septum pellucidum would retain this diagnosis postnatally. Specifically, in the absence of postnatal endocrine or ophthalmologic abnormalities, postnatal imaging would find no additional related findings, and fetuses would be at low risk for developmental delay. Two of 8 subjects met postnatal criteria for septo-optic dysplasia; remaining subjects had normal postnatal endocrine and ophthalmologic evaluations and no significant related findings on postnatal MRI. One subject without septo-optic dysplasia had delays on developmental screening; all others had normal screening (range of follow-up 8-72 months). Our study questions the necessity of postnatal imaging for prenatally diagnosed isolated absent septum pellucidum. Majority of fetuses with isolated absent septum pellucidum retained this diagnosis postnatally.

Background and purpose The cavernous sinus is a unique region owing to anatomical factors and the pathologies affecting it. The diagnosis of cavernous sinus syndrome (CSS) predominantly relies on clinicoradiological correlation. We studied the utility of computed tomographic (CT) scan versus magnetic resonance imaging (MRI) in the diagnosis of CSS. Methods A prospective observational study was conducted in a tertiary care center in north India. All patients presenting with a clinical syndrome of cavernous sinus involvement with radiologically confirmed lesions were enrolled in the study. MRI and CT scan with cavernous sinus cuts were done and reviewed by experienced neuroradiologists for cavernous sinus lesions and compared with the final diagnosis. Sensitivity and specificity were calculated. Results We included 48 patients in our study. A final diagnosis was achieved in 41 out of 48 (85.6%) patients. Fungal infections (16 (33.3%)) constituted the commonest cause of CSS, followed by neoplastic involvement (13 (27.1%)) and Tolosa–Hunt syndrome (12 (25%)). Vascular involvement was seen in three (6.3%) patients. Other rare causes were seen in four (8.3%) patients. CT scan had an overall sensitivity of 14.6% in achieving a final diagnosis, whereas MRI had an overall sensitivity of 70.7%, with a statistically significant difference ( p < 0.001). Conclusions Although CT scan is a relatively cheap and accessible resource, its role in CSS diagnosis and management is limited because of poor yield. Hence, it is prudent to do an MRI as an initial investigation in cases of CSS.

The new McDonald 2010 criteria have been recommended in paediatric multiple sclerosis (PMS). We aimed to assess the utility of McDonald 2010 criteria in comparison with 2007 International Paediatric Multiple Sclerosis Study Group (IPMSSG)-recommended criteria for PMS diagnosis. Retrospective analysis of 38 PMS cases from three UK demyelination clinics was conducted. Dissemination in space (DIS) and time (DIT) for both McDonald and IPMSSG criteria were noted on initial and follow-up magnetic resonance imaging (MRI). At first MRI scan, IPMSSG DIS criteria were fulfilled in 68% of scans and McDonald DIS criteria in 84%. In total, 11/18 children given gadolinium contrast fulfilled both McDonald DIS and DIT criteria on initial scan. The 2010 McDonald criteria appear more sensitive than IPMSSG and may allow PMS diagnosis at first presentation of CIS in at least a half of cases.

Objectives: We analyzed the magnetic resonance imaging (MRI) manifestations of fetal corpus callosum abnormalities and discussed their prognosis based on the results of postnatal follow up. Methods: One hundred fifty-five fetuses were diagnosed with corpus callosum abnormalities by MRI at our hospital from 2004 to 2019. Gesell Development Scales were used to evaluate the prognosis of corpus callosum abnormalities after birth. Results: Corpus callosum abnormalities were diagnosed in 149 fetuses from singleton pregnancies, and 6 pairs of twins, 1 in each pair is a corpus callosum abnormality. Twenty-seven cases (27/155) were lost to follow up, whereas 128 cases (128/155) were followed up. Of these, 101 cases were induced for labor, whereas 27 cases were born naturally. Among the 27 cases of corpus callosum abnormality after birth, 22 cases were from singleton pregnancies (22/27). Moreover, 1 twin from each of 5 pairs of twins (5/27) demonstrated corpus callosum abnormalities. The average Gesell Development Scale score was 87.1 in 19 cases of agenesis of the corpus callosum and 74.9 in 3 cases of hypoplasia of the corpus callosum. Among the 5 affected twins, 2 had severe neurodevelopmental delay, 2 had mild neurodevelopmental delay, and 1 was premature and died. Conclusion: The overall prognosis of agenesis of the corpus callosum is good in singleton pregnancies. Hypoplasia of the corpus callosum is often observed with other abnormalities, and the development quotient of hypoplasia of the corpus callosum is lower compared with agenesis of the corpus callosum. Corpus callosum abnormalities may occur in one twin, in whom the risk may be increased.

This is an update to the 2010 article published in Hospital Pharmacy on safety concerns involving transdermal patches and magnetic resonance imaging (MRI). Since publication of the original article, new brand and generic transdermal medications have become available and notable changes regarding the presence or absence of metallic content among existing transdermal formulations occurred. To update the tables within the article, Food and Drug Administration (FDA)-approved transdermal medications through October 2020 were researched in order to determine metallic content and procedures for reapplication after MRI, if applicable. Readers should consult the prescribing information or manufacturer for the most current information on use of transdermal medications in the MRI setting. Of note, manufacturers have not evaluated the use of transdermal products while patients undergo a MRI scan.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

The increasing use of radiological examination, especially magnetic resonance imaging (MRI), will probably increase the risk of unintended discovery of bone marrow abnormalities in patients where a hematologic disease would not be expected. In this paper we present four patients with different hematologic malignancies of nonplasma cell types. In all patients the MRI bone marrow abnormalities represent an initial presentation of the disease. These case reports illustrate the importance of a careful diagnostic follow-up without delay of patients with MRI bone marrow abnormalities, because such abnormalities can represent the first sign of both acute promyelocytic leukemia as well as other variants of acute leukemia.
