TL;DR
A 26-year-old Vietnamese man was diagnosed with hypogonadotropic hypogonadism, presenting with unoccluded growth plates. This case highlights atypical initial signs and diagnostic challenges.
A 26-year-old Vietnamese man was diagnosed with hypogonadotropic hypogonadism after presenting with atypical clinical features, including unoccluded growth plates. This case underscores the importance of considering this diagnosis even when typical skeletal maturation signs are absent, which can influence clinical assessment and management strategies.
The patient, a Vietnamese male aged 26, exhibited delayed puberty and low testosterone levels, prompting further investigation. Notably, radiological examination revealed unoccluded growth plates, a finding that is uncommon in hypogonadotropic hypogonadism cases typically associated with advanced skeletal maturation. The diagnosis was confirmed through hormonal assays showing low gonadotropins (LH and FSH) alongside low testosterone, consistent with central hypogonadism.
The case was documented in a recent medical publication, marking it as a rare initial presentation. The clinicians emphasized that unoccluded growth plates can complicate diagnosis, as they may suggest ongoing growth potential, which is unusual in adults with this condition. The report highlights the necessity for comprehensive hormonal and radiological evaluation in atypical cases.
Implications for Diagnosis and Management of Atypical Cases
This case challenges the conventional understanding that hypogonadotropic hypogonadism in adults is always associated with closed growth plates, which indicate completed skeletal maturation. Recognizing such atypical presentations is crucial for accurate diagnosis, especially in young adults with delayed puberty or other endocrine abnormalities. It also suggests that clinicians should consider hypogonadotropic hypogonadism even when radiographs show unoccluded growth plates, preventing misdiagnosis or delayed treatment.

Rare Presentation of Hypogonadotropic Hypogonadism in Young Adults
Hypogonadotropic hypogonadism is typically characterized by low gonadotropin levels leading to decreased testosterone and delayed or absent puberty. Usually, it is associated with advanced skeletal maturity in adults, evidenced by closed growth plates. However, this case report documents a rare presentation in a 26-year-old patient where growth plates remained unoccluded, which is uncommon in the literature. Prior cases have primarily focused on adolescents or confirmed skeletal maturity in diagnosis.
The report adds to the limited data on atypical presentations, emphasizing that skeletal maturity may not always align with hormonal status, especially in cases with underlying congenital or acquired hypothalamic-pituitary dysfunctions.
“This case illustrates that unoccluded growth plates can still be present in young adults with hypogonadotropic hypogonadism, which may lead to diagnostic challenges if not carefully evaluated.”

Unclear Aspects of Growth Plate Persistence in Adults
It remains unknown why some patients with hypogonadotropic hypogonadism retain unoccluded growth plates into adulthood. The case report does not clarify whether this is due to genetic factors, delayed skeletal maturation, or other underlying mechanisms. Further research is needed to understand the prevalence and implications of this atypical presentation.

Further Research and Clinical Vigilance Needed
Future studies should investigate how common unoccluded growth plates are among adults with hypogonadotropic hypogonadism and whether this affects treatment outcomes. Clinicians are advised to include radiological assessment in atypical cases and consider endocrine evaluation even when skeletal maturity appears incomplete. Monitoring and long-term follow-up of similar cases are essential to refine diagnostic criteria and treatment strategies.

Key Questions
Can hypogonadotropic hypogonadism present with unoccluded growth plates in adults?
Yes, as demonstrated by this case report, although it is rare, some adults with hypogonadotropic hypogonadism may still have unoccluded growth plates, which can complicate diagnosis.
What are typical signs of hypogonadotropic hypogonadism in young adults?
Delayed puberty, low testosterone levels, and low gonadotropins are common signs. Skeletal maturity usually indicates completed growth, but this case shows exceptions.
How does the presence of unoccluded growth plates affect treatment?
It may influence decisions regarding hormonal therapy and prognosis, but further research is needed to determine specific impacts on treatment outcomes.
Is this presentation common or rare?
This presentation is considered rare, with limited cases reported in the literature. It highlights the need for awareness of atypical manifestations.
What further research is needed on this topic?
Studies are needed to determine the prevalence of unoccluded growth plates in adults with hypogonadotropic hypogonadism and to understand the underlying mechanisms.
