Summary
A young, non-smoking male with mental retardation presented with back pain due to a rare lung cancer. Early diagnosis is crucial, especially for patients with cognitive impairments.
Area of Science:
- Oncology
- Neurology
Background:
- Large cell neuroendocrine carcinoma (LCNEC) is a rare and aggressive form of lung cancer.
- Patients with cognitive impairments may face diagnostic delays due to underestimation of symptoms.
Observation:
- A 25-year-old African-American male with mental retardation presented with four months of low back pain, anorexia, and weight loss.
- Imaging revealed an L2 vertebral body fracture, leading to surgical intervention.
- Biopsy confirmed LCNEC of lung origin, with a mediastinal mass identified on CT scan.
Findings:
- The patient's low back pain was an unusual initial presentation of metastatic lung cancer.
- Immunostaining confirmed the lung origin of the neuroendocrine carcinoma.
- Surgical management included L2 corpectomy, bone grafting, and fusion.
Implications:
- This case highlights the importance of thorough diagnostic evaluation for all patients, regardless of cognitive status.
- It underscores the need to consider metastatic disease in patients presenting with unexplained back pain.
- Raising awareness of LCNEC's varied presentations can improve patient outcomes.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
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...
