Abstract:
Introduction. Streptococcus constellatus collectively with Streptococcus anginosus and Streptococcus intermedius constitute the Streptococcus anginosus (formerly Streptococcus milleri) group. Though they are commonly associated with abscesses, bacteremia with subsequent septic thrombophlebitis is extremely rare, and resulting mortality is infrequent. Case Presentation. We report a case of a previously healthy 60-year-old African American female who presented with Streptococcus constellatus bacteremia associated with septic thrombophlebitis to the right ovarian vein extending into the inferior vena cava. She was urgently treated with antibiotics and anticoagulation. Conclusion. Septic thrombophlebitis has a clinical presentation that is often misleading. Therefore, a high clinical index of suspicion and the use of appropriate imaging modalities (computed tomography) are essential in recognizing and confirming this diagnosis. Prompt treatment is warranted. Surgical thrombectomies have been successfully replaced by a combination of antibiotics and anticoagulation therapy.
Insights
This case report details a rare instance of Streptococcus constellatus bacteremia leading to septic thrombophlebitis. Prompt antibiotic and anticoagulation therapy proved effective, highlighting the importance of early diagnosis for this uncommon condition.
Area of Science:
- Infectious Diseases
- Hematology
- Medical Case Reports
Background:
- Streptococcus constellatus is part of the Streptococcus anginosus group, typically linked to abscess formation.
- Bacteremia with septic thrombophlebitis caused by this group is exceptionally rare.
- Septic thrombophlebitis often presents with misleading clinical signs.
Purpose of the Study:
- To report a rare case of Streptococcus constellatus bacteremia with septic thrombophlebitis.
- To emphasize the diagnostic challenges and effective management strategies for this condition.
Main Methods:
- A case presentation of a previously healthy 60-year-old female.
- Utilized computed tomography (CT) for diagnosis.
- Treatment involved urgent antibiotics and anticoagulation therapy.
Main Results:
- The patient presented with Streptococcus constellatus bacteremia.
- Septic thrombophlebitis of the right ovarian vein extending into the inferior vena cava was diagnosed.
- Successful treatment was achieved with antibiotics and anticoagulation, avoiding surgery.
Conclusions:
- Septic thrombophlebitis requires a high index of clinical suspicion for timely diagnosis.
- Computed tomography is crucial for confirming the diagnosis.
- Antibiotic and anticoagulation therapy is an effective alternative to surgical thrombectomy.

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...
