Acute hematogenous osteomyelitis is the most common cause of osteomyelitis in children. It requires early diagnosis and treatment to minimize the risk of sequela of growth disturbances and deformity. We present a case of an unusual presentation of osteomyelitis of the tibia with Superficial venous thrombosis in a 2½ year male child, which was 1st ever reported association. A high degree of clinical suspicion of venous thrombosis, especially in pediatrics osteomyelitis, is required, with high C-reactive protein and erythrocyte sedimentation rate levels, as the child presents insidiously.

| Introduction|| |
It is not uncommon to encounter complicated osteomyelitis in pediatric practice. Acute hematogenous osteomyelitis is the most common source of infection in children, typically affecting the long bones such as the femur (27%) and tibia (26%). Acute osteomyelitis (13/10,000) associated with venous thrombosis is a rare presentation with an estimated incidence of 0.07/10,000.
Our case developed an unusual association of superficial venous thrombosis (SVT) and prolonged hospital course; its the first-ever reported association. SVT further led to an eccentric course in this case.
| Case Report|| |
A 2½-year-old male child was presented with fever, limp and pain full left limb swelling for 10 days. Fever was intermittent, high grade with chills. The swelling was Sudden in onset and seen from ankle to knee. The pain was dull and continuous, which started with a pain score of 3/10 and increased to 5/10, aggravated by walking and standing, slightly relieved by rest. Restricted knee and ankle movements were seen in the patient. He has a history of upper respiratory tract infection-10 days before the onset of swelling. The patient’s treatment history revealed antibiotic and adhesive bandage usage from a quack [Figure 1].
During the physical examination, the patient was pale, lethargic, irritable, and a squint of the right eye was found. During the general examination, the pulse rate was 144/min; the temperature was 103°F; blood pressure was 80/56 mm of Hg; the respiratory rate was 36/min, dorsalis pedis and posterior tibial arterial pulses were felt. Local examination of leg revealed swelling in the medial aspect of left leg, extending from ankle to knee, diffuse with ill-defined borders; overlying skin was erythematous, warm, tender to touch with no discharging sinus and soft in consistency (not attached to the skin, nonmobile). The knee and ankle have only a limited range of motion from 0° to 30°, and further movements were painful. For hip, all movements are normal, and no pain is felt. All systemic examinations were found to be normal. Differential diagnoses include osteomyelitis, septic arthritis, deep-vein thrombosis, Juvenile idiopathic arthritis, and cellulitis.
The child was admitted to the pediatric intensive care unit with suspicion of sepsis, started on ceftriaxone, and linezolid with intensive and supportive care. Laboratory findings revealed an elevated erythrocyte sedimentation rate, elevated C-reactive protein (CRP), microcytic hypochromic anemia, neutrophilic leukocytosis. Widal, HIV, surface antigen of the hepatitis B virus (HBsAg) tests showed negative. Blood and pus cultures were sterile, immune profile, and hemoglobin electrophoresis was normal. X-ray of the left leg showing mid-calf swelling extending up to mid-thigh with no bony pathology [Figure 2]. As the radiological findings of acute osteomyelitis are absent/subtle in the initial days, one cannot rule it out; one has to go for advanced investigations. Ultrasonography revealed a moderate amount of fluid seen surrounding the Left tibia. Nonsteroidal anti-inflammatory drugs, warm compresses, magnesium sulfate, dressings were provided to the patient. The child remained febrile, and painful swelling of the leg persisted despite intensive care. Vascular insufficiency was suspected, and work up was enhanced in that direction.

Colour Doppler test revealed a thrombus measuring 12 cm length, 3.5 mm width in a great saphenous vein in the upper 1/3rd of the left leg. Magnetic resonance imaging scan revealed fluid intensity noted surrounding the left tibia (1.5 cm thick and 11 cm length), Patchy marrow edema, extensive hyperintense signals throughout the length of the tibia [Figure 3] and [Figure 4]. For the osteomyelitis of the tibia with an abscess – Enoxaparin was initiated according to the American college of chest physicians protocol and continued till thrombus resolution. The abscess was drained by making a drill hole in the bone after packed red blood cells transfusion. The child was monitored meticulously for distress and pulmonary embolism. The child gradually responded to the treatment and was discharged on oral faropenam and linezolid with weekly follow-up and wound dressing.

| Discussion|| |
Acute osteomyelitis (13/10,000) associated with venous thrombosis is a rare presentation with an estimated incidence of 0.07/10,000. Hematogenous spread of osteomyelitis is the most common source of infection in children, typically affecting the long bones. The femur (27) % and tibia (26) % are most commonly affected.
The possible contributing factors for the prolonged hospital stay were anemia, delayed presentation, the possibility of methicillin-resistant Staphylococcus aureus (MRSA), cellulitis, and septic arthritis involving both the knee and ankle joints. Superficial venous thrombus further led to an eccentric course in my case [Figure 5].

Subtle or absent radiological features in the first 2 weeks mandate a high degree of clinical suspicion. Delayed diagnosis can lead to long-term sequelae/permanent disabilities. Clinical suspicion of venous thrombosis should be high, especially in pediatric osteomyelitis with high CRP, through routine screening is not needed. Early recognition and prompt treatment comprising antibiotics and anticoagulant therapy should be initiated as soon as thrombus is suspected; any delay in diagnosis may contribute to serious complications and even fatal consequences.
Our case developed an unusual association of SVT and prolonged hospital course; its first-ever reported association. The possible contributing factors for the prolonged hospital stay were delayed presentation, possibilities of MRSA, extensive osteomyelitis, and a subperiosteal abscess that might lead to septic thrombophlebitis, mismanagement by a quack might have contributed to the development of SVT. SVT further led to an eccentric course in this case.
Such cases are usually a diagnostic dilemma due to overlapping clinical presentation of SVT and osteomyelitis. Unless acute osteomyelitis in children is diagnosed early and treated appropriately, it leads to prolonged hospital safety and antibiotic administration, and it can be a devastating or even fatal disease. Awareness and a high index of suspicion of this association are necessary for an early diagnosis and prompt correct treatment.
