Parry Romberg Syndrome

Abstract Background The aim of this study was to: (i) describe the abnormalities seen on brain imaging in a group of children with en coup de sabre (EDCS) with/without Parry-Romberg syndrome (PRS); and (ii) identify clinical predictors of brain imaging abnormalities. Methods This was a single centre (Great Ormond Street Hospital, London) retrospective case series of patients with ECDS/PRS seen from 2000 to 2018. We identified patients with cutaneous manifestations consistent with the clinical descriptions of ECDS/PRS. Presenting clinical, laboratory, and radiological brain findings are described. Results are expressed as medians and ranges or frequencies and percentages. Fisher’s exact test was used to identify clinical associations with magnetic resonance imaging (MRI) abnormalities. Results Fourteen patients were studied: 6 males and 8 females; median age 14 years (range 3–20). We observed neuroimaging abnormalities in 2/6 ECDS and 5/8 ECDS/PRS patients. White matter signal abnormality, dystrophic calcification, leptomeningeal enhancement, and sulcal crowding were the typical findings on brain imaging. A total of 50% of patients had no MRI abnormality despite some of these patients having neurological symptoms. The presence of seizures was significantly associated with ipsilateral enhanced white matter signalling on MRI (p < 0.05). Conclusions In summary, we observed several distinct radiographic patterns associated with ECDS/PRS. Seizure disorder was strongly associated with the presence of ipsilateral enhanced white matter signalling. Improved neuroimaging techniques that combine morphological with functional imaging may improve the detection rate of brain involvement in children with ECDS/PRS in the future.

Cross Sectional Imaging

AbstractBackground:Isolated olfactory dysfunction is a common complaint; the vast majority of cases are benign and untreatable. A common dilemma is whether to image the olfactory tract of affected patients.Methods:A case review of 100 consecutive patients who underwent magnetic resonance imaging for the primary complaint of olfactory dysfunction was performed. Patients with a diagnosis of chronic rhinosinusitis, with or without nasal polyps, were excluded.Results:Magnetic resonance imaging abnormalities that were considered clinically relevant to the presentation of olfactory dysfunction were found in only seven patients (7 per cent). Of these, only one patient (1 per cent) had an abnormality found that altered their clinical management. A comparison of the findings for children (less than 16 years old,n = 5) with those for adults (equal to or more than 16 years old,n = 95) revealed that 4 per cent of adults scanned had olfactory-related pathology diagnosed, as opposed to 60 per cent of children.Conclusion:Cross-sectional imaging may not be necessary in most patients with olfactory dysfunction. Imaging adds little to the patient history and clinical examination findings.

AbstractObjectivesTo determine: (1) the incidence of incidental ‘mastoiditis’ reported on magnetic resonance imaging scans performed in patients with asymmetrical sensorineural hearing loss and/or unilateral tinnitus; (2) how many of those patients have actual otological pathology and/or require treatment; and (3) the financial implications of such a reporting practice.MethodRetrospective case series.ResultsBetween October 2015 and November 2016, 500 patients underwent magnetic resonance imaging of the internal auditory meatus to rule out cerebellopontine angle lesions. There was an incidental finding of increased mastoid signalling in 5.8 per cent (n= 29), of which 20.7 per cent (6 of 29) were reported as bilateral cases. The diagnosis of ‘mastoiditis’ was found in 39.7 per cent (29 of 73). None of these patients had any pathology identified clinically. Other significant pathology was identified in a further 8.8 per cent (n= 44).ConclusionThe diagnosis of mastoiditis is primarily clinical. An incidental finding of high signalling in the mastoid region on magnetic resonance imaging is highly unlikely to represent actual clinical disease. In patients who are scanned for other reasons and who do not complain of otological symptoms, such findings are unlikely to require otolaryngology input.

Hamstring Muscles

Background: As compared with injuries involving muscle only, those involving the central hamstring tendon have a worse prognosis. Limited information is available regarding the surgical treatment of central tendon injuries of the hamstrings. Purpose: To describe the operative treatment and outcomes of central tendon injuries of the hamstrings among athletes. Study Design: Case series; Level of evidence, 4. Methods: Eight athletes (6 top level, 2 recreational) with central hamstring tendon injuries underwent magnetic resonance imaging and surgical treatment. The indication for surgery was recurrent (n = 6) or acute (n = 2) central hamstring tendon injury. All patients followed the same postoperative rehabilitation protocol, and return to play was monitored. Results: Magnetic resonance imaging found a central tendon injury in all 3 hamstring muscles (long head of the biceps femoris, semimembranosus, and semitendinosus) with disrupted tendon ends. In acute and recurrent central tendon injuries, full return to play was achieved at 2.5 to 4 months. There were no adverse events during follow-up. Conclusion: Central tendon injuries of the hamstrings can be successfully repaired surgically after acute and recurrent ruptures.
