NLS-Based Diagnosis and Monitoring of Lung Abscesses
S.N. Makarova
Screening via Nonlinear Systems (NLS) diagnostics identified two cases of lung abscess in patients presenting with high fevers and acute pain in the right hypochondriac region. Initially, these patients underwent ultrasound imaging to rule out abdominal pathologies; however, NLS-investigation provided further clarity. The examinations were performed using advanced NLS diagnostic equipment featuring a 1.4GHz digital trigger sensor.
Case Study: Patient N., a 57-year-old male, was admitted to the therapeutic ward exhibiting a week-long fever reaching 40°C, a mild non-productive cough, and discomfort in the right hypochondrium following a respiratory infection. His medical history noted bilateral pneumonia fourteen years prior. Laboratory results showed elevated leukocytes at 18.7 x 109 with a significant left shift, while urinalysis was unremarkable. Physical evaluation noted vesicular breathing, which was notably diminished in the lower right lung without presence of rhonchi. Clinical signs included a dry, coated tongue and tenderness in the right abdomen, though no peritoneal irritation or Pasternatski’s signs were detected.
Abdominal NLS assessments found no abnormalities in the liver, gallbladder, or pancreas. However, significant findings emerged in the thoracic region: blackening of the diaphragmatic pleura (rated 4-5 on the Flandler scale) and a voluminous mass in the right lung (5-6 points). A heterogeneous, chromogenic formation measuring 85x65x54 mm was localized on the dorsal thoracic wall, surrounded by infiltrated lung tissue with increased chromogenic density. Spectral analysis showed a high similarity to the lung abscess reference standard (D=0.312). NLS conclusions indicated a developing abscess in the right lung, which was subsequently confirmed by radiological imaging.
A follow-up NLS scan 10 days later revealed a rounded, hypochromogenic mass (81x60x51 mm) with irregular borders. Persistent infiltration was observed in the surrounding tissue, alongside blackened pleural layers in the lower right lung. Despite a recommendation for specialized surgery, the patient opted for conservative anti-inflammatory treatment. After three weeks, he presented with a productive cough and profuse sputum. While his temperature and white cell counts normalized, his ESR remained high (37 mm/h). The NLS update showed the mass had reduced to 47x43 mm with more defined borders and decreased peripheral infiltration. The patient was eventually discharged for outpatient care.
Case Study: Patient M., 63, initially underwent NLS screening to evaluate potential gallbladder or liver issues. While the left lung appeared healthy, the right lung (spanning segments IX to XI) showed a dense, heterogeneous parietal formation of 85x60 mm with uneven outlines and small hypochromogenic inclusions. The NLS findings suggested a lung abscess, which radiology confirmed in the lower right lobe.
Monitoring continued during anti-inflammatory therapy. Ten days later, NLS revealed a more rounded formation of 73x50x60 mm with high chromogenic density (4-5 points) surrounded by infiltration. A subsequent two-week check revealed no further positive changes, indicating a plateuing in the therapy's effectiveness.
These clinical observations highlight the vital diagnostic potential of NLS-investigations for pulmonary diseases—a method currently underutilized in standard practice. Implementing dynamic NLS monitoring allows practitioners to accurately evaluate treatment success while significantly reducing radiation exposure for both patients and medical staff.
