Summary
Epidural spinal cord compression in acute lymphoblastic leukemia (ALL) is rare. A persistent mass after treatment may indicate fibrosis, not resistant disease, requiring over a year for resolution.
Area of Science:
- Pediatric Oncology
- Hematology
- Neurology
Background:
- Acute lymphoblastic leukemia (ALL) can present with rare complications like epidural spinal cord compression.
- Extramedullary disease in ALL typically affects bone, soft tissue, skin, and lymph nodes.
Observation:
- A child with B-lineage ALL presented with a spinal epidural mass.
- Initial treatment resolved symptoms but left a persistent mass.
- Biopsy revealed fibrosis, not residual tumor, after 7 months.
Findings:
- Persistent epidural masses in ALL may not signify treatment resistance.
- Complete resolution of such masses can take over a year despite adequate therapy.
Implications:
- Clinicians should consider prolonged observation for persistent epidural masses in ALL patients.
- Histological confirmation is crucial to differentiate fibrosis from resistant disease.
- This finding impacts treatment monitoring and patient management strategies for ALL with extramedullary disease.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

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...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
