Cushing's disease presenting with severe osteoporosis
Acta Endocrinologica
|February 1, 1986
Summary
Cushing's disease typically presents with many symptoms. This case highlights a rare presentation of Cushing's disease, primarily featuring severe osteoporosis and hypopituitarism, despite a pituitary adenoma.
Area of Science:
- Endocrinology
- Oncology
- Neurosurgery
Background:
- Cushing's disease, a condition caused by excess cortisol, usually has a distinct set of clinical signs.
- Pituitary adenomas are common causes of Cushing's disease, leading to hormonal imbalances.
Observation:
- A unique case of Cushing's disease is presented, stemming from a pituitary adenoma.
- The patient exhibited severe osteoporosis as the predominant clinical manifestation.
- Unusually severe hypopituitarism was also noted in this patient.
Findings:
- The pituitary adenoma in this patient led to Cushing's disease with atypical symptoms.
- Osteoporosis was the most prominent sign, diverging from the typical presentation of Cushing's disease.
- The co-occurrence of severe hypopituitarism alongside Cushing's disease suggests complex pituitary dysfunction.
Implications:
- This case underscores the importance of considering atypical presentations in diagnosing Cushing's disease.
- Understanding rare clinical manifestations aids in refining diagnostic strategies for pituitary adenomas.
- Further research into the relationship between pituitary adenomas, Cushing's disease, osteoporosis, and hypopituitarism is warranted.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
