III. Infections
a. Tuberculosis:
-TB on the chest wall can occur as an isolated
primary infection with no evidence of pulmonary
disease
- Spread to the chest wall from pulmonary infection
may also occur althrough symptoms may be minor
- Presentation may be similar to pyogenic abscess or
simply an enlarging mass.
Chest wall lesions in childhood
b. Actinomycosis : rare, may mimic TB with pulmonary
infiltration and spread to the chest wall
c. Aspergilosis: in immunocompromised patients, usually
by local invasion from the lung.
d. Progenic abscess
: Staphylococcus, Klebsiella infection
e. Other infection illness: Strongyloidiasis (Strongyloides
stercoralis)糞小桿線蟲

1. Tietze syndrome: infectious costochondritis

Inflammation of the costal cartilages (Costochondritis) with a
large, tender, fusiform (spindle-shaped), nonsuppurative
swelling at the costochondral or chondrosternal junction.
Principles and Practice of Pediatric Infectious Diseases, 2nd ed

Etiology:
-Exact cause unclear
-Most often idiopathic
-Associated with excessive exercise, chest injury or a preceding
viral respiratory illness (postinfectious)
1. Tietze syndrome



Epidemiology
-Generally occurs in late teens to early twenties, but has been
described in young children.
S/s: sharp pain in anterior chest wall, may radiate to
back or upper abdomen.
: varies in intensity and quality.
PE: Tender by palpation at local site or movements of
the arm or shoulder.
:May show evidence of tachypnea, tachycardia or
systolic HTN.
: Distortion of local soft tissue.
1. Tietze syndrome
Diagnostic workup
-Made with historical and physical clues.
-Biopsy: increased cartilage and lack of inflammatory
fibrosis.
 Management:
NSAIDs, Injections into the painful area with
triamcinolone are sometimes curative.
Question: Fever ? preceding viral respiratory illness?

2. Pleurodynia
Nelson 17ed p1045, Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183


Etiologic agents are most frequently coxsackieviruses B3 and
B5, as well as coxsackieviruses B1 and B2 and echoviruses 1
and 6.
Nelson 17ed p1045
Sex: Males are affected more than females. Half of these
patients are younger than 5 years, and 30% are younger than 1
year.

Coxsackievirus B usually causes an asymptomatic or brief
upper respiratory tract or gastroenteric infection. Nelson 17ed p1045

The virus has an incubation time of 1 week in the GI tract and
subsequently involves the target organs through hematogenous
dissemination.
2. Pleurodynia
Nelson 17ed p1045, Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183

Prodromal symptoms such as malaise, myalgias, headache
and diarrhea are followed by sudden onset of fever and pain.
Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183

Involvement of the intercostal and other muscles of respiration
results in enhanced pain with deep breathing and a sensation of
“pleuritic” pain that can result in splinting of the chest and rapid,
shallow breathing.
Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183


Pain, typically located in the chest or upper abdomen, and is
spasmodic and can be excruciatingly severe. Nelson 17ed p1045
During spasms, respirations are usually rapid, shallow, and
grunting, pale, sweaty, and shock-like appearance.Nelson 17ed p1045
2. Pleurodynia
Nelson 17ed p1045, Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183



Causes necrosis of the striated intercostal muscles in patients
with pleurodynia.
Muscle tenderness can be detected by direct palpation; less
commonly, localized swelling is observed ( Sylvest, 1934 )
Associated symptoms related to the viral infection may include
the following:
-Upper respiratory tract symptoms, including sore throat, rhinitis,
and cough.
-Constitutional symptoms, including headaches (50%), fever,
and malaise
2. Pleurodynia
Nelson 17ed p1045, Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183
-GI symptoms, including nausea, vomiting, diarrhea (50%), and in
children, abdominal pain (usually in the epigastric area)
 Diagnosis:
-Viral cultures(throat) isolation of coxsackievirus B in cell
cultures .
-RT-PCR(throat)
-Histologic Findings: Necrosis of the striated intercostal muscles
is visible .
-Serum creatine kinase is usually elevated because of muscle
necrosis.
-CxR: reveals clear lung fields; less than 10% of patients have a
pleural friction rub or pleural fluid evident on chest radiographs.
2. Pleurodynia
Nelson 17ed p1045, Principles and Practice of Pediatric Infectious Diseases, 2nd ed P1183




Illness usually lasts 3–6 days, but can last up to a
couple of weeks.
Illness may occasionally be associated with meningitis,
orchitis, myocarditis, or pericarditis.
Management:
-Analgesics and limitation of physical activity are helpful in
reducing pain, which is generally most severe on
presentation and then progressively diminishes during the
course of illness (which is typically 4 to 6 days but which
may last as long as 3 weeks) ( Warin et al., 1953)
Question: Serum creatine kinase within normal range
3. Tuberculosis
Principles and Practice of Pediatric Infectious Diseases, 2nd ed
I. Bony tuberculosis
 Osteomyelitis is otherwise most frequently found in the
metaphysis of long bones, although the ribs, pelvis
and skull may be infected.
 In children in countries in which TB is prevalent,
osteomyelitis is a significant cause of crippling
deformity.
 Trauma does not predispose to tuberculous
osteomyelitis
3. Tuberculosis
Principles and Practice of Pediatric Infectious Diseases, 2nd ed


Bony TB may be accompanied by sinus tracts or soft
tissue masses.
Diagnosis:
-May be difficult because lesions can appear osteolytic
or sclerotic on radiography.
-Biopsy : acid-fast bacilli (AFB) stains, culture or PCR
3. Tuberculosis
Principles and Practice of Pediatric Infectious Diseases, 2nd ed
II. Tuberculous abscesses:
 May form in most soft tissues, including muscle .
 This is usually secondary to contiguous spread of infection but
may follow hematogenous dissemination.
 The classic abscess site is in the psoas muscle, and such an
abscess can occur with or without localizing signs
 Cough, diarrhea and vomiting can be happened, but rare and
chronic when the pulmonary and gastointestinal were involved.
 Question: Contact history? insidious enlarging mass? Chronic
steroid usage? Body weight loss? Night weating?
4. Actinomycosis



Nelson Textbook of Pediatrics, 17th
Actinomyces israelii , a slow-growing, gram-positive bacteria
that are part of the normal oral flora in humans.
Infection caused by these bacteria is termed actinomycosis,
which is a chronic, granulomatous, suppurative disease
characterized by peripheral spread with extension to contiguous
tissue in the formation of numerous draining sinus tracts.
7% of the patients <10 yr of age. The youngest patient in this
series was 28 days old.
4. Actinomycosis




Nelson Textbook of Pediatrics, 17th
Actinomycosis is usually not an opportunistic infection, disease has been
described in patients receiving corticosteroids and those with leukemia,
renal failure, congenital immunodeficiency diseases, and HIV infection
three important sites of Actinomyces infection in order of frequency are
cervicofacial, abdominal, and thoracic
Pulmonary actinomycosis may present as fever, productive cough, chest
pain, and weight loss.
Infection frequently dissects along tissue planes and may extend through
the chest wall or diaphragm, producing numerous sinuses.
4. Actinomycosis



Nelson Textbook of Pediatrics, 17th
Diagnosis : confirmed by examining purulent sinus tract
drainage for sulfur granules, and by appropriate cultures.
The differential diagnosis of pulmonary actinomycosis includes
lung abscess and tuberculosis.
Tx: mainstay of treatment for actinomycosis is prolonged
antibiotic therapy (Penicillin) and an appropriate surgical
approach to sinus tracts and abscesses.
4. Actinomycosis
Nelson Textbook of Pediatrics, 17th
Question: Chronic process, underlying
immunocompromise status; diarrhea? Vomiting?
5. Pneumonia- Pyogenic Empyema Necessitatis



Pyogenic Empyema Necessitatis:
A rare complication of empyema; is a collection of
inflammatory tissue that usually extends directly from
the pleural cavity into the thoracic wall forming a mass
in the extrapleural soft tissues.
The hallmark of empyema necessitatis is a mass
The most common etiologies are tuberculosis and
actinomycosis.
5. Pneumonia- Pyogenic Empyema Necessitatis



1-year-old boy with Streptococcus pneumoniae
empyema necessitatis and review previously
reported . Pediatr Infect Dis J - 01-FEB-2004; 23(2): 177-9
Symptoms: as the underlying disease, fever, chest
pain, chest wall mass,cough and short of breath may
be occur.
Pediatr Infect Dis J - 01-FEB-2004; 23(2): 177-9
The mass might be painful and fluctuant.
5. Pneumonia- Pyogenic Empyema Necessitatis

Diagnosis:
-Chest radiograph:
Pleural effusion, with thickening of the pleura at the
involved site, may be an enlargement of the overlying
ribs with a thick, calcified pleural rind.
-CT scan:
may show a thick-walled, possibly well-encapsulated, pleural
mass that protrudes through the chest wall.(Virtually diagnostic
of empyema necessitatis)
5. Pneumonia- Pyogenic Empyema Necessitatis
Questions: Rare chronic complication of pneumonia,
decreased breath sounds, dull percussion on
physical examination, vomiting, diarrhea?
6. Pyogenic abscess



Pyogenic abscesses involving Staphylococcus or
Klebsiella infection of the chest wall may also occur
and may be due to central line or catheter-related
sepsis in immunocompromise.
Large multifocal lesions may develop .
Question: diarrhea, vomiting? Cough? No predisposing
factor? Not multifocal mass?
7. Osteomyelitis: Rib or sternum




Nelson 17ed P2297
Most cmmon in young children, more common in boy
than girl(2:1)
The majority of infection in otherwise healthy children
are hematogeneous origin.
Long bone is principlly involved in osteomyelitis (2.9%
in chest bones)
Blunt trauma, bacteremia, illness, malnutrition, immune
system deficiency have been described as
predisposing conditions.
7. Osteomyelitis


Etiology: S. aureus is the most frequently isolated
pathogen excluding patients with hemoglobinopathies,
such as SCD, where Salmonella sp. is more likely .
Primary viral infections of bone are exceedingly rare, but
accompanied viral syndrome, suggesting immune-mediated
pathogenesis.
Nelson 17ed P2298
- Extremely rarely, the viruses which cause chickenpox and
smallpox have been found to cause a viral osteomyelitis.
7. Osteomyelitis


Clinical features may including chills, fever,chest
pain,tenderness,swelling and erythema over the
involved bone.
Scand J Infect Dis 1999 ;31: 98–100.
Insidious onset of nonspecific symptoms associated
with gradual painful swelling over the bone area.

Pediatr Infect Dis J 2001; 20: 547–50
7. Osteomyelitis
Diagosis:
-CBC: leukocytosis with left shift, and a thrombocytosis may be
present.Pediatric Clinics of North America 43: 933-947, 1996
-ESR and CRP are the nonspecific sign of inflammation.
-Culture taken from the bone, either surgically or by needle
aspiation.
-CT or Three phases bone scan
 Question: More insidious process? Chickenpox? Smallpox?

8. Strongyloidiasis (Strongyloides stercoralis)

8. Strongyloidosis (Strongyloides stercoralis)

Pulmonary disease secondary to larval migration through the lung rarely occurs and
may resemble Löffler's syndrome (cough, wheezing, shortness of breath, and
transient pulmonary infiltrates accompanied by eosinophilia).
Nelson 17ed P1160
Clinical manifestations of strongyloidiasis in southern Taiwan.
J Microbiol Immunol Infect - 01-MAR-2002; 35(1): 29-36
