Lung cancer commonly metastasizes to the skeletal system, and when affecting the spine, it may initially be mistaken for a typical musculoskeletal source of back pain. We report a previously healthy 52-year-old male non-smoker with an eight-week history of low back pain that radiated into his left thigh and recent weight loss, yet no respiratory symptoms. Initially, the patient visited his primary care physician, who suspected a musculoskeletal condition and prescribed a nonsteroidal anti-inflammatory drug and muscle relaxant, then referred the patient to the chiropractor. Based on the patient's pain pattern, limited mobility, and other features, the chiropractor suspected a lumbar disc herniation. However, the patient's condition worsened during a one-week trial of care, so the chiropractor ordered magnetic resonance imaging (MRI) and, as the findings suggested vertebral metastasis, promptly referred the patient to an oncologist, who confirmed a diagnosis of lung adenocarcinoma via positron emission tomography (PET)/computed tomography and biopsy. Chiropractors should be aware of warning signs of malignancy, such as unexplained weight loss or progressive worsening despite treatment. If providers suspect spinal metastasis, they should order advanced imaging such as an MRI and refer patients to an oncologist for timely care.

Cases of lumbar and gluteal pain are commonly encountered in chiropractic clinics, with a broad differential diagnosis primarily centered on musculoskeletal conditions. This report presents the second documented case of sacral chordoma diagnosed at a chiropractic clinic and emphasizes the importance of considering alternative diagnoses and interdisciplinary collaboration in patient care. A 42-year-old man presented to a chiropractic clinic with complaints of lumbar and gluteal pain. The initial conservative management based on a presumptive musculoskeletal diagnosis was ineffective. Suspicion of an alternative etiology prompted a referral for imaging, which revealed a sacral chordoma. An interdisciplinary collaboration involving orthopedic surgeons, oncologists, radiologists, and other healthcare professionals was initiated to optimize the treatment outcomes of this rare and aggressive tumor. This case report underscores the importance of maintaining a high index of suspicion in cases of musculoskeletal presentations in chiropractic clinics and the critical role of advanced imaging in establishing a definitive diagnosis. Interdisciplinary collaboration is essential for managing complex conditions such as sacral chordomas, ensuring the delivery of the highest quality of care, and optimizing patient outcomes. Chiropractors play a crucial role in identifying, referring, and contributing to the management of patients with complex presentations as part of a comprehensive multidisciplinary treatment plan.

A 67-year-old woman presented to a chiropractor with a four-week history of neck and low back pain, lower extremity paresthesia, profound fatigue, and cutaneous pallor. Previous cervical radiographs had revealed multilevel degenerative spondylosis. However, abnormal hematological indices, including severe thrombocytopenia and anemia, prompted concerns of an underlying hematopoietic malignancy. Interdisciplinary collaboration facilitated expedient hematological assessment, confirming acute lymphoblastic leukemia (ALL), as evidenced by lymphoblasts in a peripheral blood smear and bone marrow biopsy. Karyotyping detected a Philadelphia chromosomal mutation; the patient therefore received oral targeted tyrosine kinase inhibition coupled with serial intrathecal chemotherapy. Complete remission was achieved. However, sensorimotor symptoms persisted due to herpetic neuralgia secondary to immunosuppression. This complex case underscores the role of chiropractors as primary contact clinicians in identifying sinister pathologies underlying musculoskeletal complaints via judicious history-taking, physical evaluation, and interpretation of investigational findings. Interprofessional collaboration is pivotal in formulating an effective therapeutic strategy to improve the prognosis of patients with this disease.
