The association of consumptive hypothyroidism secondary to hepatic hemangioma and severe heart failure in infancy

Infantile Hepatic Hemangioma: A Novel Approach Using Propranolol and Transarterial Embolization

Benign vascular tumors, or hemangiomas, are common in young children. The most frequent way to identify them on the skin is as bright red surface lesions, although they can also be detected deeper as subcutaneous lesions. Visceral involvement, particularly of the liver, is commonly observed in patients with multiple cutaneous hemangiomas. Since most hemangiomas are self-limited, they can be clinically monitored. Despite this, hepatic hemangiomas can result in significant consequences, such as severe hepatomegaly, which can induce abdominal compartment syndrome, inadequate ventilation, and renal vein compression, as well as significant arteriovenous shunts that compromise the functioning of the heart. Depending on the patient's findings, management may range from routine follow-up to liver transplantation. Here, we present a case of hypothyroidism, hepatomegaly, and cardiac failure in a two-month-old female newborn with infantile hepatic hemangioma. The patient's symptoms were managed with the use of levothyroxine, propranolol, and transcatheter arterial embolization (TAE).

Consumptive Hypothyroidism due to Hepatic Hemangiomas: A Case Series and Review of the Literature

Consumptive hypothyroidism (CH) is a rare and potentially overlooked complication of hepatic hemangiomas (HH) overexpressing the enzyme deiodinase, which converts thyroxine (T4) to reverse triiodothyronine (rT3).

Materials and methods

Here, we report a case series of 3 patients and a systematic review of the literature.

Results

Hypothyroidism (mean serum TSH 52.03 mIU/L) was detected at a mean age of 4.6 months (range 3-6) in 3 infants with infantile hepatic hemangiomas, treated with thyroxine (mean dose 12 µg/kg/day). All received treatment with propranolol (1-3 mg/kg/day) from the mean age of 4 months. Hormonal treatment was stopped at a mean age of 20 months (range 12-30). Hypothyroidism reoccurred in a patient concurrently with the increase of liver lesions, requiring liver transplantation (LT) at age 39 months.Literature review retrieved 42 studies (48 patients): HH (n = 43) were isolated in 24 infants and associated with cutaneous hemangiomas in 19. Hemangiomas were only cutaneous in 5.In the first 43 patients, hypothyroidism was detected at a mean age of 1 month; 21 of 43 patients were prescribed propranolol alone (n = 8) or associated with other medicaments (n = 13); 2 of 43 patients underwent LT. Hormonal treatment consisted of T4 in 35 of 43 patients and T3 in 10.CH associated with only cutaneous and extrahepatic visceral hemangiomas (n = 5), detected at a mean age of 7 months (TSH mean levels at diagnosis of 150.3 mIU/L). Three of 5 patients received treatment with propranolol ± other medicaments. All 5 patients were treated with T4.

Conclusions

Periodical thyroid function assessment is necessary in patients with hepatic hemangiomas, particularly when lesions' size and number increase rapidly.

Multiple infantile hepatic hemangiomas leading to consumptive hypothyroidism successfully treated with propranolol: A case report

Hepatic hemangioma is a commonly encountered benign vascular tumour of liver during infancy. Acquired hypothyroidism is one of the rare manifestation of this entity. We report a 4-month-old infant born to a diabetic mother who developed acquired hypothyroidism not responding to treatment due to multiple hepatic hemangiomas. The mechanism behind is increased type 3 deiodinase activity due to hemangiomas of liver, which catalyses conversion of T4 to rT3 and T3 to T2. Hemangiomas were successfully treated with propranolol which lead to its regression and ultimately resulted in euthyroidism. Hence, screening for hepatic hemangioma should be done in all cases of congenital hypothyroidism not responding to thyroxine treatment. We also propose early initiation of treatment of hemangiomas with propranolol as the first line therapy to prevent growth retardation and intellectual loss.

Infantile hepatic hemangioendothelioma associated with pulmonary artery hypertension and cardiac insufficiency successfully treated with transcatheter arterial embolization and propranolol: A case report

INTRODUCTION

Infantile hepatic hemangioendothelioma is a type of benign hepatic tumor that occurs in infancy. Many hepatic tumors are diagnosed when screening is done for multiple cutaneous hemangiomas. Hepatic tumors are small multifocal lesions and are mostly asymptomatic. There have been many case reports of asymptomatic infantile hepatic hemangioendothelioma, but few of these have pointed out that hepatic hemangiomas can sometimes be life-threatening due to fatal hepatomegaly complications such as pulmonary artery hypertension or even congestive heart failure. At present, there are no standard protocols for treating infantile hepatic hemangioendothelioma, though most clinicians agree that treatment is unnecessary for multiple small hepatic hemangiomas in asymptomatic patients. Little is known about treatment for cases with life-threatening complications induced by infantile hepatic hemangioendothelioma as there are so few reported cases. Here, we report a special case with hepatomegaly, pulmonary artery hypertension, and cardiac insufficiency induced by infantile hepatic hemangioendothelioma.

PATIENT CONCERNS

We present a case with hepatomegaly, pulmonary artery hypertension, and cardiac insufficiency caused by infantile hepatic hemangioendothelioma.

DIAGNOSIS

Infantile hepatic hemangioendothelioma was diagnosed.

INTERVENTIONS

The patient underwent transcatheter arterial embolization and was given propranolol.

OUTCOMES

The patient responded well to treatment with transcatheter arterial embolization and propranolol. The patient gained weight steadily, liver volume, and mass size have decreased considerably, echocardiography showed normal pulmonary artery pressure and ejection fraction, and we discovered no serious complications after 1 year of follow-up.

CONCLUSION

Transcatheter arterial embolization combined with propranolol is an effective treatment for life-threatening infantile hepatic hemangioendothelioma.

Resolution of Consumptive Hypothyroidism Secondary to Infantile Hepatic Hemangiomatosis with a Combination of Propranolol and Levothyroxine

Infantile hepatic hemangiomas (IHH), particularly of the diffuse subtype can, in severe cases, be associated with hepatic and cardiac failure, compartment syndrome and consumptive hypothyroidism. Early recognition and treatment of these pathologies is paramount in order to minimise the risk of long-term sequelae. We report an interesting case of a female infant who presented with systemic compromise, in the absence of large or obvious cutaneous infantile hemangiomas. Imaging identified innumerable hepatic hemangiomas, consistent with diffuse infantile hepatic hemangiomatosis. Subsequent to this, thyroid function tests confirmed an associated but comparatively rare form of hypothyroidism, known as consumptive hypothyroidism. Following joint consultation with dermatology and endocrinology she was promptly treated with oral propranolol and levothyroxine, with subsequent improvement in her clinical parameters. This case reiterates the importance of aggressive investigation and management of consumptive hypothyroidism in any infant diagnosed with IHH, particularly when there is systemic compromise. We advocate propranolol as a single first line treatment for IHH, supported by thyroid replacement when appropriate.

Consumptive Hypothyroidism: Case Report of Hepatic Hemangioendotheliomas Successfully Treated with Vincristine and Systematic Review of the Syndrome

OBJECTIVES

To provide a comprehensive description of consumptive hypothyroidism syndrome (CHS), a severe form of hypothyroidism that occurs due to the high expression levels of thyroid hormone inactivation enzyme type 3 deiodinase (D3) in tumors.

STUDY DESIGN

Case report and systematic review.

RESULTS

A 7-month-old girl with a diagnosis of massive hepatic hemangioendotheliomas was treated with high doses of thyroid hormones and tumor-directed chemotherapy with vincristine. The tumor displayed excellent response, and euthyroid status was regained. A systematic review on the databases PubMed/Medline and Embase was performed, using the term "Consumptive AND "Hypothyroidism." From the 33 selected references, we extracted 42 case reports of CHS: 36 children and 6 adults. The laboratory profile at diagnosis displayed high TSH and low T4 and T3 serum levels. The serum reverse T3 and D3 activity levels were high in all patients tested. In children, 97% had vascular tumors, whereas in adults 33% were vascular tumors, 33% fibrous tumors, and 33% gastrointestinal stromal tumors. The conservative treatment was predominant in children, while in adults all cases were treated with surgery. Death occurred in 16% of children and 33% of adults.

CONCLUSIONS

CHS is a rare form of hypothyroidism that occurs in children and adults, usually linked to hepatic vascular tumors. The condition is associated with high lethality. Prompt diagnosis, followed by high-dose thyroid hormone replacement and tumor-directed therapy are the keys to optimize outcomes.

Diffuse hepatic hemangioma with single cutaneous hemangioma: an alerting occurrence

Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. However, diffuse hepatic hemangioma can develop even in patients with single cutaneous hemangioma. This highlights the importance of physical examination and screening ultrasound in these patients.
