A Case of Slipped Capital Femoral Epiphysis in Association With Craniopharyngioma

Slipped capital femoral epiphysis with hypopituitarism in adults: A case report and literature review

RATIONALE

Slipped capital femoral epiphysis (SCFE) is a common disease in pediatric orthopedics. Most research on SCFE has focused on high-risk groups or the whole population, and studies focusing on adult SCFE patients are rare. In the present study, we report the case of an adult patient with SCFE.

PATIENT CONCERN

A 37-year-old man presented to our clinic with persistent pain that was poorly localized to both hips, groin regions, and thighs for more than 1 year.

DIAGNOSES

A bilateral hip X-ray examination was performed, and the femoral epiphyses were found to be unfused on both sides. Low levels of growth hormone (GH), insulin-like growth factor-1 (IGF-1), triiodothyronine (T3), thyroxine (T4), follicle-stimulating hormone, luteinizing hormone, estradiol, and testosterone, and high levels of thyroid-stimulating hormone, prolactin, and cortisol.

INTERVENTIONS

Hormone-substitution therapies (levothyroxine sodium to treat hypothyroidism and testosterone enanthate to treat hypogonadism) were prescribed. Total hip arthroplasty was performed to treat femoral epiphysis slippage.

OUTCOMES

After 6 months of postoperative follow-up, the patient's gait improved significantly, and bilateral hip pain was relieved.

LESSONS

When treating adults with SCFE, clinicians must be alert to endocrine disorders. Comprehensive imaging evaluation is crucial for the accurate diagnosis and selection of an appropriate treatment.

Association of Slipped Capital Femoral Epiphysis With Panhypopituitarism Due to Pituitary Macroadenoma: A Case Report

Slipped capital femoral epiphysis (SCFE) commonly occurs in overweight or obese adolescents, but can also be associated with endocrine disorders including hypothyroidism, pituitary tumors, and growth hormone deficiency. In this article, we present a case of panhypopituitarism that initially presented with SCFE. A 16-year-old male presented with right SCFE. After a right hip open reduction and percutaneous pinning procedure, findings of skeletal maturity that lagged behind his chronologic age and a delayed Tanner stage resulted in a referral to an endocrine specialist. Endocrine laboratory evaluation identified elevated prolactin levels (1493 ng/mL), hypogonadotropic hypogonadism, and central adrenal insufficiency as evidenced by low morning cortisol level of 1.0 µg/dL. Magnetic resonance imaging revealed a large pituitary T2 isointense mass measuring 1.8 × 2.7 × 2.3 cm. The patient was diagnosed with panhypopituitarism due to a pituitary macroadenoma. Multidisciplinary collaboration for treatment of this patient consisted of oral cabergoline, oral levothyroxine, oral hydrocortisone therapy, intramuscular testosterone therapy, and a prophylactic closed reduction percutaneous pinning of the left hip due to high risk of also developing SCFE of the left hip. Panhypopituitarism should be considered as a diagnosis after atypical presentations of SCFE. In our case, an astute clinical assessment resulted in prompt endocrine referral and management of panhypopituitarism. Our report highlights the importance of multidisciplinary collaborations to guarantee early detection of endocrinopathies in patients with SCFE undergoing surgical interventions in order to avoid potential complications, such as adrenal crisis during surgery.

Slipped Capital Femoral Epiphysis in an Adult Patient With Kabuki Syndrome

Introduction:

Slipped capital femoral epiphysis (SCFE) is a condition which predominantly occurs in adolescents. SCFE is extremely rare in adults, and nearly all previous reported cases have been associated with an endocrine disorder.

Methods:

We present a case of a 19-year-old man with Kabuki syndrome who was diagnosed with an unstable SCFE requiring surgical fixation. A literature search on PubMed and Google Scholar was done looking for all published cases of delayed-onset SCFE. All previous reported cases were reviewed to determine the likely cause of the SCFE.

Results:

No previous cases of SCFE were described in patients with Kabuki syndrome. Literature review revealed 27 articles describing 32 cases of delayed-onset SCFE. Thirty-one of these cases were associated with endocrine disorders or pituitary tumors. Endocrine disorders associated with delayed-onset SCFE included hypothyroidism, hypogonadism, and panhypopituitarism. Pituitary adenomas and craniopharyngiomas were also associated with delayed-onset SCFE.

Discussion:

This is the first reported case of SCFE in a patient with Kabuki syndrome. Kabuki syndrome is a genetic disorder known to cause delayed growth, resulting in delayed physeal closure, placing the patients at risk of SCFE even into adulthood. The literature search revealed that nearly all previously described delayed-onset SCFE cases were associated with endocrine disorders or pituitary tumors. We recommend that all patients diagnosed with delayed-onset SCFE be evaluated for endocrine disorders, pituitary tumors, and/or genetic disorders which can cause delayed skeletal maturation as these disorders can range from severe endocrine disorders to intracranial tumors.

Slipped capital femoral epiphysis in an adult with congenital hypopituitarism: A case report

RATIONALE

Slipped capital femoral epiphysis (SCFE) is a common hip problem in adolescents, usually individuals between 8 and 15 years old. Because of the frequent finding of growth abnormalities in affected children, various endocrine disturbances have been reported as the cause of the disease. However, there are few case reports of older patients in previous literature. To the best of our knowledge, congenital hypopituitarism with normal growth hormone (GH) level has not been reported.

PATIENT CONCERNS

We describe a 29-year-old man who had a 3-month history of pain in the left hip with tall stature and unobvious secondary sexual characteristics. Laboratory testing showed low thyroxine, low cortisol, low follicle-stimulating hormone, low luteinizing hormone, low testosterone, but normal GH.

DIAGNOSES

Brain magnetic resonance imaging showed pituitary hypoplasia. An anteroposterior pelvis radiograph showed severe varus SCFE in the left hip, it was also confirmed with computed tomography scans.

INTERVENTIONS

The patient was treated with levothyroxine, hydrocortisone, and testosterone replacement therapy before surgery. We performed open reduction and anatomical reduction by Dunn's procedure.

OUTCOME

We have followed this patient for 6 months, the left hip mobility gradually improved. No slip in the contralateral proximal femoral physis has been observed.

LESSONS

When unobvious secondary sexual characteristics and body abnormalities were found in clinical practice, endocrine condition should be evaluated, since the contralateral side may prone to slip due to the lack of endocrine therapy.

Xanthomatous hypophysitis causing hypogonadotropic hypogonadism resulting in delayed presentation of slipped capital femoral epiphysis

An 18-year-old man who underwent bilateral pinning of his hip joints after a left unstable Slipped Capital Femoral Epiphysis (right pinned prophylactically) was noted to have delayed secondary sexual characteristics and post-operative diabetes insipidus. The patient also described a history of fatigue, headache and polydipsia for the past 4 years. Endocrine investigations revealed reduced androgen levels, hypocortisolism, a borderline normal Serum ACE and secondary hypothyroidism. Magnetic Resonance Imaging of the pituitary gland identified an enhancing mass and a thickened stalk which trans-nasal endoscopic biopsy found to be necrotic with pus. Histology confirmed a diagnosis of Xanthomatous Hypophysitis, an inflammatory condition likely related to a partial rupture of a Rathke cleft cyst. The patient was subsequently commenced on Androgen, Thyroxine, Desmopressin and Hydrocortisone therapy with on-going endocrine follow-up. Although endocrine dysfunction & hypogonadism has been recognised to be a risk factor for SCFE at an atypically older age, due to reduced androgen levels leading to a weakened physeal plate, this is the first known case of a Xanthomatous Hypophysitis resulting in pituitary dysfunction and eventual SCFE. This case highlights that an increased range of pituitary disorders should be considered in late presentations of SCFE; and vice versa the risk of SCFE should be considered in patients with prolonged hypogonadotropic hypogonadism.
