Bone-related disorders of the jaw: A clinico-radiological diagnostic algorithm

The Relationship ◽

Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.

Abstract Aim The purpose of our study was to analyze the clinical and imaging features of uterine carcinosarcoma (UCS) and cervical carcinosarcoma (CCS), and to explore the diagnostic and staging accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) examinations. Methods 41 patients including 37 with UCS and 4 with CCS from July 2011 to September 2020 were enrolled in the study. Of the 37 UCS cases, 7 had CT images, 27 had MRI images, and 3 had both CT and MRI images. The Clinical data, CT or MRI imaging findings were analyzed. Diagnosis and staging accuracy of CT and MRI images were also analyzed. Results Carcinosarcoma usually occurs in postmenopausal women (40/41), with the typical clinical symptom being vaginal bleeding (33/41). The CA125 degree was significantly different between the two invasion depth groups (p = 0.011). Most uterine carcinosarcomas showed unclear boundaries, uneven density, low or equal signal on T1WI, high or mixed signal on T2WI, uneven high signal on diffusion-weighted image (DWI), and mild enhancement. The diagnostic accuracies of CT and MRI for carcinosarcoma were 0% and 3.33%, respectively. The diagnostic accuracy for malignant tumors on CT and MRI was 50% and 83.33%, respectively. Conclusions Carcinosarcoma lesions presented with huge mass filling in the cavity, and some presented with small polypoid lesions or endometrial thickening. Evaluation of lymph node metastasis is a significant challenge for imaging staging.

Pathological Subtypes

Objective: To retrospectively analyze magnetic resonance imaging (MRI) features of various pathological subtypes of sinonasal rhabdomyosarcoma (RMS) and explore correlations between imaging features and pathological subtypes. Methods: In total, 11 cases with embryonal, alveolar or pleomorphic sinonasal RMSs, confirmed by surgical pathology, were selected. Their characteristics and distinctive imaging features were analysed, and the correlation between pathology and imaging features was explored. Results: Bone destruction was observed in all 11 cases with RMS. Expansive growth was predominant in three alveolar and three embryonal RMS cases, and creeping growth was predominant in two alveolar, two embryonal and one pleomorphic RMS cases. Signs of residual mucosa were observed in all 11 cases, and 10 cases showed involvement of multiple sinus cavities and orbital cavities. All cases exhibited mild-to-intermediate enhancement. Conclusion: Sinonasal RMSs have the following characteristic MRI features: ethmoid sinuses and middle nasal conchae are the prevalent sites; lesions are mainly of mild enhancement; tumours exhibit signs of residual mucosa, mild-to-intermediate enhancement and frequent orbital involvement; bone invasion and bone destruction are frequently observed; and haematogenous metastasis is not as common as lymphatic metastasis. RMSs of various pathological subtypes were not significantly distinct by imaging.

AbstractLacunarity, a quantitative morphological measure of how shapes fill space, and fractal dimension, a morphological measure of the complexity of pixel arrangement, have shown relationships with outcome across a variety of cancers. However, the application of these metrics to glioblastoma (GBM), a very aggressive primary brain tumor, has not been fully explored. In this project, we computed lacunarity and fractal dimension values for GBM-induced abnormalities on clinically standard magnetic resonance imaging (MRI). In our patient cohort (n = 402), we connect these morphological metrics calculated on pretreatment MRI with the survival of patients with GBM. We calculated lacunarity and fractal dimension on necrotic regions (n = 390), all abnormalities present on T1Gd MRI (n = 402), and abnormalities present on T2/FLAIR MRI (n = 257). We also explored the relationship between these metrics and age at diagnosis, as well as abnormality volume. We found statistically significant relationships to outcome for all three imaging regions that we tested, with the shape of T2/FLAIR abnormalities that are typically associated with edema showing the strongest relationship with overall survival. This link between morphological and survival metrics could be driven by underlying biological phenomena, tumor location or microenvironmental factors that should be further explored.

Gadolinium-enhanced magnetic resonance imaging (MRI) is very sensitive in the detection of active lesions of multiple sclerosis (MS) and has become a valuable tool to monitor the evolution of the disease either natural or modified by treatment. In the past few years, several studies, on the one hand, have assessed several ways to increase the sensitivity of enhanced MRI to disease activity and, on the other, have investigated in vivo the nature and evolution of enhancing lesions using different non-conventional MR techniques to better define the relationship between enhancement and tissue loss in MS. The present review is a summary of these studies whose results are discussed in the context of MS clinical trial planning and monitoring.

Retroperitoneal lymphangiectasia is a very rare lymphatic disorder characterized by abnormal proliferation of lymphatics. We present series of 3 cases of retroperitoneal lymphangiectasia which are diagnosed in our institute with the help of Ultrasonography (USG), Computed Tomography (CT) and Magnetic resonance imaging (MRI) of abdomen and pelvis with unusual clinical presentation. We include clinical features and imaging findings of this disorder with its pathogenesis and diagnosis. Two of the cases were clinically masquerading as hernia and one case was mimicking varicocele. Thorough clinical examination and USG, colour Doppler, CT and MRI are extremely helpful imaging investigation that aid in differentiating these lesions from hernia/ varicocele and the cross sectional imaging like CT and MRI can depict the anatomical extent of the disease.

The study was carried out in 103 patients with psoriasis, who had the consultation of dermatologist and rheumatologist. Answers for 6 questions mPEST (Psoriasis Epydemiology Screening Tool) modified questionnaire were estimated, each positive answer corresponded to 1, PEST ≥ 3 was suggested the presence of psoriatic arthritis (PsA), PEST < 3 was considered the absence of PsA. All the patients were examined by rheumatologist, the gold standard was CASPAR (ClASsification criteria for Psoriatic Arthritis) criteria. If necessary the instrumental tests were performed: roentgenography, ultrasound examination, magnetic resonance imaging (MRI) and laboratory tests. At PEST ≥ 3 diagnosis of PsA was suspected in 60 (58.2%) of 103 patients. Diagnosis of PsA was confirmed by CASPAR criteria in 47 (45.6%) patients. mPEST less than 3 was in 43 (41.7%) of 103 patients. Diagnosis of PsA was absent by CASPAR criteria in 29 (67.4%) patients. Newly diagnosed PsA was in 32 (52.4%) of 61 patients. Any rheumatic disease, mainly PsA, can develop with psoriasis. mPEST questionnaire in most cases reveals PsA in early stage, however, its isolated use is insufficient to establish an accurate diagnosis, it requires a clear diagnostic algorithm of the disease, including consultation of rheumatologist, clinical and instrumental examination.
