“…Similarly, the previously described increased posterior through‐transmission was not seen in these cases as a specific feature, as this finding was present in 20% of masses from cat scratch disease and 25% from other causes. An additional finding, the presence of a markedly increased Doppler signal within involved nodes, has been previously identified as a suggestive feature of cat scratch disease, possibly related to neovascularization resulting from Bartonella infection, which may also produce vasoproliferative lesions involving the skin, brain, bone marrow, and mucosal surfaces 21 – 23 . The conspicuity of this feature on power Doppler imaging has been described as the “fire” pattern 12 .…”

“…The presence of a subcutaneous nodule in the patient's groin area, which later developed into hyperemia of the skin, could represent the site of entry for Leptospira . As Bartonella also presents with self-limiting lymphadenopathy in the draining site of cat scratch [ 11 ], this infection was also suspected, but serological analysis revealed negative results.…”

Leptospirosis, a zoonotic infection caused by the Leptospira bacteria, can manifest with varying clinical severities, ranging from subclinical disease to severe multiorgan failure. This progression to severe multiorgan failure, also known as multi-organ dysfunction syndrome (MODS), is a life-threatening condition characterized by the dysfunction of two or more organ systems. Often, MODS is a consequence of events triggered by underlying pathologies, such as severe infections, including those caused by Leptospira . Here, we present a case report of a 29-year-old female patient who initially sought care for increased temperature, fatigue, diarrhea, and vomiting. The patient exhibited signs of septic shock (SS). Her medical history raised suspicion of multiple potential sources of infection. She experienced cat scratch several days before admission, accompanied by an enlarged inguinal lymph node and a history of frequent interaction with animals, as well as freshwater exposure, which prompted investigations into various zoonotic infections. Empiric treatment was started, and, subsequently, after several days, Leptospira titer came back positive. Over the hospitalization course, the patient developed multi-organ failure, which was attributed to the underlying Leptospira infection. The complexity and severity of the patient's condition underscore the far-reaching impact of leptospirosis in precipitating a spectrum of systemic complications culminating in multiorgan failure. The treatment interventions yielded successful outcome, and the patient recovered in one month. This case report highlights the difficulties in diagnosing and treating patients with multiple possible sources of infection. it emphasizes the need for a careful history-taking and high level of suspicion for zoonotic infections in patients with a history of animal exposure and clinical symptoms suggestive of infectious diseases.

“…Bacterial proliferation results in the release of proinflammatory chemicals and growth regulators and the cessation of apoptosis, which manifests as new lumps inside the vascular system. The signs can mimic cancer in half of cases, and in a minority of instances, they are connected with the musculoskeletal system, including osteitis, arthritis, and myositis [ 30 , 31 ]. In usually healthy subjects, the disease progresses slowly and may self-regulate.…”

The Clinical Profile of Cat-Scratch Disease’s Neuro-Ophthalmological Effects

et al. 2022

View full text Add to dashboard Cite

Cat-scratch disease is an illness caused by Bartonella henselae that occurs as a result of contact with an infected kitten or dog, such as a bite or scratch. It is more prevalent in children and young adults, as well as immunocompromised individuals. There are limited publications examining the features of CSD in patients. As such, the purpose of this research was to assess the clinical neuro-ophthalmological consequences of CSD reported in the literature. Among the ophthalmologic disorders caused by cat-scratch disease in humans, Parinaud oculoglandular syndrome, uveitis, vitritis, retinitis, retinochoroiditis and optic neuritis are the most prevalent. The neurological disorders caused by cat-scratch disease in humans include encephalopathy, transverse myelitis, radiculitis, and cerebellar ataxia. The current review addresses the neuro-ophthalmological clinical manifestations of cat-scratch disease, as described in papers published over the last four decades (1980–2022). All the data gathered were obtained from PubMed, Medline and Google Scholar. The current descriptive review summarizes the most-often-encountered clinical symptomatology in instances of cat-scratch disease with neurological and ocular invasion. Thus, the purpose of this review is to increase knowledge of cat-scratch disease’s neuro-ophthalmological manifestations.
