Three Signs to Help Detect Sjögren's Syndrome: Incidental Findings on Magnetic Resonance Imaging and Computed Tomography. J Clin Med 2023; 12:6487. [PMID: 37892630 PMCID: PMC10607120 DOI: 10.3390/jcm12206487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 10/04/2023] [Accepted: 10/10/2023] [Indexed: 10/29/2023] Open
Abstract
This study aimed to retrospectively investigate the prevalence of Sjögren's syndrome (SS) among patients with ranulas, parotid cysts, or parotid calcifications; identify the characteristic magnetic resonance imaging (MRI) or computed tomography (CT) findings of the lesions associated with SS; and compare the SS disease stages among SS patients with the three lesion types. A total of 228 patients with the lesions were classified into SS, possible SS, and non-SS groups. The prevalence of SS among patients with ranulas, parotid cysts, or parotid calcifications was 16%, 24%, and 40%, and the rates of either SS or possible SS were 25%, 41%, and 64%, respectively. SS was associated with (i) ranulas: ≤17 mm; (ii) parotid cysts: bilateral and multiple; and (iii) parotid calcifications: in females, bilateral, multiple, parenchymal, and no coexisting calcifications in other tissues. SS patients with ranulas were significantly younger and had lower submandibular gland stage scores on MRI/CT than those with other lesions. Additionally, in 58% and 15% of SS patients with ranulas and parotid calcifications, respectively, detection of the lesions led to the diagnosis of primary SS. Therefore, recognizing the prevalence of SS among patients with these lesions and the findings associated with SS can help detect undiagnosed SS.

[PMID: 34307628 PMCID: PMC8281396 DOI: 10.12998/wjcc.v9.i20.5701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 04/13/2021] [Accepted: 05/24/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Although the presentations of Sjögren’s syndrome (SS) are variable, ranging from mild dryness to wider systemic involvement, ranulas as early clinical signs were scarcely reported. Here, we present an adult patient with SS, who developed a unilateral simple ranula and was diagnosed primary SS 3 years later. We also provide a review of cases of SS and ranulas from 1980 to 2020.
CASE SUMMARY A 22-year-old girl was found to have a left painless floor-of-mouth lesion 3 years ago, without obvious trauma or inducement. The diagnosis of a unilateral (left) simple ranula was made, and the ranula was surgically treated. Within 3 years after the ranula surgery, she developed acute lymphadenectasis in unilateral parotid twice without inducement, and ultrasonic examination revealed diffuse lesions in bilateral parotids and submandibular glands, which strongly suggested SS. Serologic tests and the unstimulated whole saliva flow rate confirmed the SS diagnosis.
CONCLUSION Our study underlines that ranulas are early clinical signs of SS. As early diagnosis and early intervention of SS are important to obtain better outcomes, our findings underline the need for histopathological test after sublingual adenectomy and imaging detection of exocrine glands for the patients with ranulas.

THE LANCET. RHEUMATOLOGY 2021; 3:e138-e148. [PMID: 38279369 DOI: 10.1016/s2665-9913(20)30393-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 10/23/2020] [Accepted: 10/29/2020] [Indexed: 01/28/2024]
Abstract
Sjögren's syndrome was considered for many years a disease of adulthood, characterised by immune infiltration of exocrine glands, leading to dryness (eg, dry mouth and eyes), which is a cardinal symptom. As of the last 20 years, it became apparent that although the disease is very rare in children, its clinical presentation differs from that of adults, posing substantial challenges to the recognition, diagnosis, and classification of patients with childhood-onset Sjögren's syndrome. This Viewpoint explores comparative classification criteria for children (not validated) and adults with Sjögren's syndrome, as well as differences in the clinical presentation of childhood-onset versus adult-onset Sjögren's syndrome, offering ideas about how we can improve the diagnosis of Sjögren's syndrome in children. A review of the role of medical history and clinical assessment, serology, glandular function assessment, and imaging, as well as salivary and lachrymal gland biopsy in the diagnosis of children with Sjögren's syndrome is included. Additionally, we provide suggestions about further research and registry data collection that is required to address the unmet needs of these patients.

Oral Radiol 2020; 37:328-335. [PMID: 32803681 PMCID: PMC7985099 DOI: 10.1007/s11282-020-00473-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 08/02/2020] [Indexed: 12/30/2022]
Abstract
Juvenile primary Sjögren’s syndrome (pSS) is rare. Although recurrent parotitis is reported to be the most common symptom of juvenile pSS, the clinical symptoms and features of the syndrome are not well understood and are poorly defined. Here we report a rare case of juvenile pSS in a patient with plunging ranula. The patient had no symptoms other than swelling of the oral floor and had no symptoms of parotitis. Magnetic resonance imaging (MRI) revealed the diagnosis of plunging ranula. In addition, the findings of the bilateral parotid glands on MRI and subsequent ultrasonography (US) strongly suggested SS. On the basis of these imaging findings and laboratory data, a pediatric rheumatologist confirmed the diagnosis of juvenile pSS. The ranula may be one clinical sign of SS. However, this association remains generally unknown. Hypothesizing that SS might cause ranula development, we retrospectively investigated cases of patients with ranula who underwent MRI at our hospital. We found that many of these patients (> 20%) had characteristic findings strongly suggestive of SS. This result suggests that SS-induced changes in the sublingual glands are one cause of ranula formation. We think that ranula is a sign of early-stage SS. Therefore, patients with ranulae, whether adults or children, should undergo careful assessment of not only the sublingual glands but also the parotid and submandibular glands with MRI and/or US to investigate possible SS. This assessment may lead to early detection of SS.
