Summary
A rare case of infected congenital dermal sinus (CDS) in a baby
Area of Science:
- Pediatric Surgery
- Dermatology
- Radiology
Background:
- Congenital dermal sinus (CDS) is a rare developmental anomaly.
- Lateral CDS in the buttocks is exceptionally uncommon, with few reported cases.
- Early diagnosis and treatment are crucial for preventing complications.
Observation:
- A 6-month-old infant presented with a purulent discharge from a buttock dimple and a palpable subcutaneous abscess.
- Infection indicators included low-grade fever, leukocytosis, and elevated C-reactive protein.
- Cultures identified Klebsiella and Enterococcus species in the abscess pus.
Findings:
- Computed tomography (CT) and magnetic resonance (MR) imaging revealed a subcutaneous tract connecting the dimple to the abscess.
- MR imaging excluded spinal canal abnormalities.
- Surgical excision confirmed the dermal sinus tract ending at the subcutaneous abscess.
Implications:
- Lateral congenital dermal sinus should be considered in the differential diagnosis of buttock dimples.
- Advanced imaging (CT and MR) is essential for evaluating suspected lateral CDS.
- Prompt surgical intervention after infection control can lead to favorable outcomes.

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:11Overview of Systemic Veins
Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

01:21External Anatomy of the Kidney
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
