Thyroid Troubles: A Case of Hypothyroidism-Associated Recurrent Massive Pleural Effusion. Cureus 2024; 16:e58072. [PMID: 38738057 PMCID: PMC11088483 DOI: 10.7759/cureus.58072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/11/2024] [Indexed: 05/14/2024] Open
Abstract
Pleural effusions can be secondary to several different etiologies. Sometimes, they can be related to hypothyroidism. We present a case of massive pleural effusion resulting from hypothyroidism. A 75-year-old male with a history of liver cirrhosis, hypothyroidism, and medication non-adherence presented to the emergency department (ED) with shortness of breath and altered mental status. Physical exam and chest imaging were consistent with right-sided pleural effusion. Effusion was exudative. Multiple recurrences complicated the hospitalization despite thoracentesis and pleurodesis. Labs revealed hypothyroidism, and finally, the patient was started on hormone replacement, resulting in the resolution of the effusion. Pleural effusion is a rare manifestation of hypothyroidism, thought to be mediated by vascular endothelial factors. Pleural fluid analysis shows both exudative and transudative patterns. Hormonal replacement is the mainstay of treatment. Clinicians need to be aware of the rare etiologies of pleural effusion. Depending on the patient's presentation, due work-up should be done to ensure a timely diagnosis and management.

Life-Threatening Cardiac Arrhythmias in a Case of Undetected Myxedema Coma: Importance of Early Detection and Medication Adherence. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e941414. [PMID: 37925597 PMCID: PMC10637760 DOI: 10.12659/ajcr.941414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 09/26/2023] [Accepted: 08/25/2023] [Indexed: 11/06/2023]
Abstract
BACKGROUND Myxedema coma is a rare, life-threatening condition caused by a severe form of hypothyroidism. The dangerously low levels of circulating thyroid hormone can lead to progressive mental status changes and numerous organ dysfunctions, including serious cardiac abnormalities. CASE REPORT We present a case of a 59-year-old woman who presented with altered mental status and fall who was originally thought to have a cerebrovascular accident but was later diagnosed with myxedema coma, after multiple cardiac arrests. It was discovered that the patient had not been taking any of her medications for the last several weeks, after her primary care provider retired from practice. Initial laboratory evaluation was significant for a TSH level of 159.419 mIU/L and an undetectable free T4 level. Complications of the myxedema coma resulted in QTC interval prolongation, causing torsades de pointes and sustained polymorphic ventricular tachycardia, requiring cardioversion. CONCLUSIONS This case demonstrates the importance of early detection and treatment of myxedema coma, as it can cause life-threatening cardiac arrhythmias. It also emphasizes the need to ensure proper medication adherence in patients with chronic medical conditions, as non-compliance can result in dire consequences.

Large Pericardial Effusion Secondary to Generalized Myxedema from Undiagnosed Hashimoto's Thyroiditis. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e940631. [PMID: 37718508 PMCID: PMC10516321 DOI: 10.12659/ajcr.940631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 08/03/2023] [Accepted: 07/27/2023] [Indexed: 09/19/2023]
Abstract
BACKGROUND Pericardial effusions are considered to be present when accumulated fluid within the pericardial sac exceeds the small amount that is normally present, causing impairment in the diastolic filling of the right heart. This case demonstrates an uncommon presentation of a large pericardial effusion by showing its relationship to myxedema in a patient with untreated hypothyroidism. CASE REPORT A 42-year-old man with a past medical history of hypertension, diabetes mellitus, and opioid abuse presented to the emergency department due to altered mental status, for which he received Narcan without resolution of symptoms. Computed tomography (CT) of the brain was without any acute intracranial abnormalities to explain the patient's altered mental status. CT chest reported a pericardial effusion, with a subsequent transthoracic echocardiogram (TTE) showing a moderate-to-large circumferential effusion without right atrial/ventricular collapse and no cardiac tamponade physiology. On further investigation, he was found to have severe hypothyroidism with elevated thyroid peroxidase antibodies. Endocrinology was consulted to start IV levothyroxine and liothyronine to treat autoimmune Hashimoto's thyroiditis. Subsequent TTE after starting hypothyroidism treatment showed an ejection fraction (EF) of 45-50% with mildly reduced left ventricular systolic function and moderate-to-large pericardial effusion, with no evidence of tamponade physiology. After treatment of hypothyroidism, the thyroid panel, EF, and pericardial effusion improved significantly. CONCLUSIONS This case illustrates the potential for suffering a large pericardial effusion secondary to generalized myxedema in a patient with severe hypothyroidism from undiagnosed Hashimoto's thyroiditis. It is important to recognize this condition for appropriate therapy and prevention of worsening cardiac conditions.

Abstract
Myxedema coma is a rare, but potentially fatal condition due to severe hypothyroidism, and most commonly seen in patients with long standing, untreated hypothyroidism. Here, I report a case of a 75-year-old male who presented to the emergency department with acute respiratory failure and altered mental status. Interestingly, this case led to a new diagnosis of hypothyroidism presenting in its most severe form - myxedema coma. This case highlights the diagnostic challenges in identifying patients with myxedema coma and recognizing its potential role as a cause of respiratory failure.

Abstract
Graves disease is an immune-mediated process characterized by the presence of autoantibodies to thyrotropin receptors. Its stimulating action on the thyroid gland causes diffuse glandular growth and increased hormone production. Graves disease is characterized by a subacute onset of non-specific, neuromuscular, cardiovascular, gastrointestinal, and eye symptoms, sometimes followed by skin manifestations, such as thyroid dermopathy or myxedema. In pediatrics, Graves disease is rare (although it is the most frequent cause of hyperthyroidism). However, the chronology of symptom onset has been well described; the development of dermopathy in the absence of other symptoms of hyperthyroidism and without eye involvement is rare. Here we describe the case of a 15-year-old female patient with thyroid dermopathy due to Graves disease without eye disease or other associated clinical symptoms of hyperthyroidism.

Abstract
In children, hypothyroidism usually presents non-specific symptoms; symptoms can emerge gradually, compromising a timely diagnosis. We report the case of a 13-year-old male, who was admitted to the hospital due to swelling of the torso and neck. Besides these symptoms, the child was healthy, except for a significant growth delay. Ultrasound evaluation and blood tests led to the diagnosis of myxedema secondary to severe hypothyroidism, which was due to autoimmune thyroiditis. Further investigations revealed pericardial effusion and pituitary hyperplasia, with hyper-prolactinemia. Treatment with levothyroxine led to edema regression and clinical, hemato-chemical and radiological improvement. After 6 months, growth velocity increased, although the recovery of growth already lost was not guaranteed. Brain MRI showed regression of pituitary hyperplasia. The diagnostic delay in this case was probably due to the patient's apparent good health, and the underestimation of growth restriction. This report underlines the importance of growth monitoring in adolescence, a critical period for identifying endocrine conditions; if undiagnosed, these conditions can lead to serious complications, such as myxedema in hypothyroidism, with potential effects beyond growth on multiple organs.

Abstract
Myxedema coma is an emergency that develops from non-diagnosed or severe
hypothyroidism and requires early recognition and management. Cardiac
manifestations are uncommon and pose a challenge in the recognition of myxedema
coma. We present the case of a 76-year-old male with a history of thyroidectomy
secondary to a follicular carcinoma, who presented with dyspnea, generalized
edema, drowsiness, disorientation, memory loss, and episodic generalized
tonic-clonic seizures. Antiepileptic and diuretic treatment for seizures and
heart failure exacerbation did not improve the symptoms. Further blood analysis
revealed a thyroid-stimulating hormone and free thyroxine of 163 mUL/L and
0.64 ng/dL, respectively. Treatment with intravenous hydrocortisone and
levothyroxine led to progressive clinical improvement. Uncommon clinical
manifestations such as cardiac and non-specific neurologic symptoms should be
considered as manifestations of myxedema coma. A comatose mental status is not a
universal manifestation, and milder symptoms should be considered. An adequate
assessment, including diagnostic scores and prompt hormonal supplementation
prevents fatal consequences.

Abstract
The SARS-CoV-2 virus can trigger thyroid dysfunction. Thyroid dysfunctions after COVID-19 vaccination have been rarely reported. We report the case of overt hypothyroidism in a 61-year-old woman seen after BNT162b2-mRNA vaccination. This case underlines the fact that thyroid function should also be monitored after COVID-19 vaccination, especially in at-risk subjects.

Abstract
BACKGROUND AND OBJECTIVE The term myxedema psychosis (MP) was introduced to describe the occurrence of psychotic symptoms in patients with untreated hypothyroidism, but the optimal assessment and treatment of this condition are unclear. We aimed to synthesize data from the literature to characterize the clinical presentation and management of MP. METHODS We performed a systematic review according to the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines in PubMed (Medline), Embase, Google Scholar, and Cochrane databases, including observational studies, case series, and case reports published from 1/1/1980 to 31/12/2019 in the English language. Descriptive statistics along with univariate and multivariate analysis were used for data synthesis. RESULTS Out of 1583 articles screened, 71 case reports met our inclusion criteria providing data on 75 MP cases. The median age at diagnosis was 42 years [32-56]. About 53% had no prior hypothyroidism diagnosis. Delusions occurred in 91%, with a predominance of persecutory ideas (84%), while hallucinations occurred in 78%. Physical symptoms and signs of hypothyroidism were absent in 37% and 26%, respectively. If symptoms occurred, nonspecific fatigue was seen most frequently (63%). The median thyroid-stimulating hormone value was 93 mIU/L [60-139]. Thyroid peroxidase antibodies were found positive in 75% (23/33) of reported cases. Creatinine kinase was reported abnormal in seven cases. Cranial imaging (CT or MRI) and electroencephalogram were normal in 89%, 75%, and 73% of the cases reported. The majority of patients were treated orally with thyroxine in combination with short-term antipsychotics. More than 90% of them showed complete recovery. Univariate analysis revealed a trend towards a shorter duration of psychosis with IV thyroid hormone therapy (p= 0.0502), but the effect was not consistent in a multivariate analysis. CONCLUSION While we identified a substantial lack of published research on MP, our pooled analysis of case observations suggests that the condition presents a broad spectrum of psychiatric and physical symptoms lending support to the value of screening for thyroid dysfunction in patients with first-ever psychosis.

Abstract
RATIONALE With the absence of ophthalmopathy, thyroid dermopathy especially lesions at atypical locations is a very rare presentation. We herein report an original case of bilateral breast myxedema caused by Grave's disease. PATIENT CONCERNS A 21-year-old unmarried woman presented with a 4-month history of Grave's disease and a 1-month history of progressive bilateral breast enlargement. She had symmetrical bilateral breast enlargement with redness and nonpitting thickening of the skin, diffusely enlarged thyroid glands, and no exophthalmos. DIAGNOSIS Ultrasonography, magnetic resonance imaging scan, and skin biopsy confirmed the diagnosis of bilateral breast myxedema. INTERVENTIONS The patient was treated with multipoint subcutaneous injections of triamcinolone acetonide in each breast every month. OUTCOMES The bilateral breast returned approximately to its normal size after therapy for 6 months. CONCLUSIONS Our case illustrates that multipoint subcutaneous injection of glucocorticoids is beneficial for bilateral breast myxedema.

Abstract
Pretibial myxedema (PM) is a rare extrathyroid condition seen in about 0.5 to 4.3 percent of individuals with hyperthyroidism due to Graves' disease, often presenting with associated thyroid orbitopathy. In most cases, patients with PM have elevated levels of thyroid antibodies, such as thyroid peroxidase (TPO), thyroglobulin, and-most especially-thyroid-stimulating hormone receptor antibodies. We present a rare case of biopsy-proven PM in a euthyroid patient with no history of Graves' disease or Hashimoto's disease. TPO and thyroglobulin antibody counts were slightly elevated but less than what is typically seen in PM and thyroid-stimulating hormone receptor antibodies (thyrotrophin-binding inhibitor immunoglobulin) were negative.

Abstract
Myxedema coma occurs mostly in patients with long-standing untreated or undertreated hypothyroidism. Bradycardia is a well-known cardiac manifestation for myxedema coma; however, not all bradycardia with hypothyroidism are sinus bradycardia. Sick sinus syndrome is a group of arrhythmias caused by the malfunction of the natural pacemaker of the heart. Tachy-Brady syndrome is considered to be a type of sick sinus syndrome, where the heart alternates between tachycardia and bradycardia, and it is usually treated with pacemaker implantation along with rate slowing medical therapy. Here we report a case of an 83-year-old female who presented with myxedema coma and atrial fibrillation with tachycardia and intermittent slow ventricular response. We attempt to review the relationship between these two diseases and conclude that appropriate diagnosis of myxedema coma, may be beneficial in reducing the need for pacemaker implantation.

Abstract
Hypothyroidism is one of the common comorbidities seen in patients with psychiatric conditions. Sometimes few patients may present with neuropsychiatric symptoms such as cognitive slowing, depression, or psychosis (“myxedema madness”). These patients are managed with antipsychotic medications while admitting laboratory works are processed. It has been found that antipsychotic use is associated with lower free thyroxine levels, so untreated hypothyroid patients may experience worsening of symptoms with antipsychotic use. It is recommended that hypothyroid patients with psychosis be treated for the underlying hypothyroidism with thyroid hormone replacement. In this article, we are presenting a case of a hypothyroid patient presenting to a psychiatric facility for worsening psychosis and persecutory delusions, and medication non-compliance to levothyroxine. We also discuss the management of psychosis in a patient with worsening hypothyroidism with a combination regimen: levothyroxine and risperidone.

Abstract
BACKGROUND Myxedema psychosis (MP) is a rare presentation of hypothyroidism. Although known for >70 years, a significant lack of systematic literature describing this condition exists. This limits the clinician's ability to identify and manage this entity properly. Hence, we aimed to systematically review the literature and summarize the presentation, diagnosis, management, and outcomes of this rare entity. METHODS Systematic review following PRISMA guidance. We will perform a comprehensive search of PubMed, Medline, Embase, Google Scholar (first 300 hits), and Cochrane databases for published observational studies, case series, and case reports. We will use descriptive statistics to provide summary estimates of demographics, common presenting features, laboratory test results, imaging findings, treatment administered, and outcomes. Moreover, continuous variables will be compared by the Wilcoxon Mann Whitney test, whereas categorical variables will be assessed by the χ test. Bivariate and multivariate regression will be performed to assess risk factors associated with poor outcome. A scoping review revealed that a meta-analysis might not be feasible owing to the paucity of systematic studies describing the condition. RESULTS This is the first systematic review examining this rare entity. Thus, the result of which will be significant. We hope that this review will help in identifying relevant predictive clinical or laboratory characteristics. Additionally, it identifies the best treatment strategies. The findings of this review will help increase our knowledge of this condition so as to recognize this condition promptly. Also, it will assist in differentiating MP from masqueraders, such as Hashimoto encephalopathy (HE). The results of this review will be published in a peer-reviewed journal. CONCLUSION This is the first systematic review exploring MP demographics, diagnosis treatment, and outcomes. The information gathered by this review will be necessary for patients, clinicians, researchers, and guideline makers. PROSPERO REGISTRATION NUMBER CRD42020160310.

We describe a case of myxedema ascites in a 64-year-old male with a history of hypothyroidism noncompliant with medical therapy who presented with syncope, hematemesis, melena, and abdominal distension. The patient received intravenous levothyroxine with a good response and improved upon discharge. This case highlights the importance of considering hypothyroidism as an etiology of unexplained ascites. The analysis of ascites from myxedema may not always have a significantly elevated protein (>2.5g/dL). Appropriate diagnosis should also rely on the clinical presentation along with a rapid and positive response to thyroid hormone replacement therapy.

Abstract
BACKGROUND Hypothyroidism is referred to be a rare but possible cause of hyponatremia. However, there is only poor evidence supporting this association. Since hyponatremia and hypothyroidism are both common conditions themselves, co-occurrence does not have to be causal. METHODS To address a potential relationship, a retrospective analysis of data from the Division of Endocrinology of the Medical University of Vienna from April 2004 to February 2016 was performed. A total of 8053 hypothyroid patients (48 ± 18 years of age; 71% female) with thyrotropin >4.0 μIU/mL and available blood tests for free thyroxine and sodium (Na+) within maximal ± seven days were included and screened for hyponatremia. Patients' records were searched for concomitant disease and medication when Na+ concentration was <135 mmol/L. RESULTS Hyponatremia was present in 448/8053 (5.56%) patients. Analysis of medical history revealed potential alternative causes of hyponatremia in 442/448 (98.88%) patients (i.e., side effects of medication, concomitant underlying disease, or other endocrine disorders). This distribution did not differ between patients suffering from clinical or subclinical hypothyroidism. No case of clinically relevant hyponatremia (Na+ < 130 mmol/L), present in 111/448 (24.78%) patients could be attributed only to hypothyroidism. There was a very weak but statistically significant trend toward a positive association between thyroid function and serum Na+ levels (Na+/thyrotropin: R = 0.022, p = 0.046; Na+/free thyroxine: R = -0.047, p < 0.001). CONCLUSION The results suggest that hypothyroid patients with moderate to severe hyponatremia often have other potential explanations for their low serum Na+ concentrations in routine care.

Abstract
Less than four percent of patients with hypothyroidism develop ascites. Ascites as the presenting feature of hypothyroidism is uncommon, hence diagnosis is often delayed. Once it is diagnosed, treatment of hypothyroidism leads to quick clinical improvement in ascites. We report a case of a female patient who presented with ascites secondary to severe hypothyroidism and discuss the diagnostic characteristics of the ascitic fluid in myxedema ascites on the basis of literature review.

Radiation therapy as part of the therapeutic regimen for extensive multilocular myxedema in a patient with exophthalmos, myxedema and osteoarthropathy syndrome: A case report. Oncol Lett 2015; 9:2404-2408. [PMID: 26137080 DOI: 10.3892/ol.2015.2990] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2014] [Accepted: 02/13/2015] [Indexed: 01/04/2023] Open
Abstract
Exophthalmos, myxedema and osteoarthropathy (EMO) comprise the triad known as EMO syndrome, which is rarely observed in patients with autoimmune thyroid disease. The present study reports the case of a patient with EMO, including the response of this rare combination to radiotherapy. A 48-year-old patient with EMO syndrome presented to the Department of Radiation Oncology, University Hospital of Muenster, eight years prior to writing with therapy-resistant pretibial myxedema and hypertrophic osteoarthropathy of the metacarpal bones. The patient had been diagnosed with Graves' disease (GD) 26 years prior to presentation, which was treated by thyroidectomy and radioiodine therapy. Four years subsequent to the diagnosis of GD, the patient developed exophthalmos, which was treated using radiotherapy. An evident pretibial, foot and hand myxedema developed within the 10 years following the onset of orbitopathy. The skin lesions were treated using radiation therapy subsequent to the failure of multiple surgical procedures and medical treatments. Almost eight years subsequent to the administration of irradiation, no recurrence was observed on the lower right leg, nor was any recurrence on the lower left leg observed approximately four years subsequent to the completion of radiotherapy. However, an additional lesion on the left hand demonstrated slow progression following treatment with radiation therapy. The present study indicates that radiation therapy can be considered as adjuvant therapy for patients with refractory myxedema, to prevent or delay the recurrence of myxedema subsequent to surgical excision.

Abstract
Myxedema madness is a very rare but established entity. A psychotic patient having hypothyroid features should always be evaluated regarding same. A 30-year-old female without known significant past medical history had, for the past one and half year, continuous persecutory and referential delusions; second and third person auditory hallucinations, facial puffiness and Brief Psychiatric Rating Scale (BPRS) score of 41 on admission. Her thyroid profile was: Thyroid stimulating hormone - 63.71 mIU/L, Free tri iodo threonine (FT3) - 2.1 pg/ml, free tetra iodo thyronine (FT4) - 0.6 ng/ml with normal ultrasound-thyroid. Patient was started on thyroxin 100 μg with a low dose risperidone 2 mg. Risperidone was withdrawn over a week and the patient was discharged on thyroxin alone with BPRS score of 8 and absence of delusions and hallucinations.

Abstract
Ogilvie's syndrome [acute colonic pseudo-obstruction (ACPO)] presents as massive colonic dilatation without a mechanical cause, usually in critically ill patients due to imbalanced sympathetic and parasympathetic activity. The initial therapy remains conservative with supportive measures (correction of metabolic, infectious or pharmacologic factors) followed by neostigmine and decompressive colonoscopy. Surgery is reserved for patients with clinical deterioration or with evidence of colonic ischemia or perforation. A 60-year-old lady presented with fever, altered sensorium, obstipation, bradycardia and abdominal distension. Investigation revealed hyponatremia and acute colonic pseudo-obstruction. Supportive measures and decompressive colonoscopy were not of great benefit. Thyroid profile was suggestive of primary hypothyroidism. Colonic motility was restored only on starting thyroxin. The case is illustrative of the need to consider hypothyroidism, a common endocrine disorder, in the differential diagnosis of Ogilvie's.

Abstract
Myxedema ascites caused by hypothyroidism is rare, so its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a 71-yr-old man with clinical ascites that was the first manifestation of hypothyroidism, and which resolved completely in response to thyroid hormone replacement therapy. To our knowledge, this is the first report of myxedema ascites in Korea. A review of the literature revealed 51 well-documented cases of myxedema ascites. Analyses of ascites from patients in this condition usually show high protein (>2.5 g/dL) and low white blood cell counts, with a high proportion of lymphocytes. A consistent feature is the good response to thyroid hormone replacement therapy, which has always led to resolution of the ascites. Myxedema ascites is thus rare but easy to treat; it should be borne in mind, especially if the ascites fluid has a high protein content.

Abstract
We report the first child presenting to the emergency department with undiagnosed myxedema in whom incidental detection of pericardial effusion led to diagnosis. Moreover, this patient presented with the highest serum thyrotropin concentration reported to date, a phenomenon that caused the hook effect during laboratory analysis. We discuss key elements of the recognition and management of hypothyroidism in the pediatric population and emphasize the importance of annual screening for hypothyroidism in all patients with Down syndrome.
