An 11-year-old male Norwegian cat was presented with a 3-week history of weakness, dysorexia, tachypnea, dyspnea, and weight loss. Thoracic point-of-care ultrasound (POCUS) revealed severe bilateral pleural effusion without cardiac chamber enlargement. Blood work including serum protein electrophoresis (demonstrating polyclonal gammopathy) was suggestive of FIP. Analyses of pleural effusion consisted of real-time PCR being positive for FCoV nucleic acids with a high viral load and slightly equivocal increased NT-proBNP. Together with the noncardiogenic nature of the effusion, these findings were consistent with a diagnosis of FIP. Three days after the presentation, the cat exhibited progressive dyspnea secondary to newly collected pleural effusion with markedly increased NT-proBNP. At that time, echocardiography revealed left ventricular wall thickening and left atrial enlargement, thus suggesting hypertrophic cardiomyopathy or myocarditis with left-sided congestive heart failure. Cardiac troponin I concentration was increased. Nine days after admission, the patient was discharged on cardiac therapy and nucleoside analog GS-441524. Fifteen days after initiation of GS treatment, echocardiography showed a decrease in left ventricular wall thickness. No long-term complications or recurrences of FIP or myocardial hypertrophy were observed at the 1.5-, 4-, and 18-month follow-ups, with normalization of cardiac troponin I concentration and echocardiographic variables, thus supporting the hypothesis of FIP-related transient myocardial thickening.

At 1.5 months of age, both cats were vaccinated with a vaccine containing the FHV-1 MLV strain F2 at another clinic. A few days later, they developed sneezing and ocular discharge almost simultaneously. Ten days after vaccination, they were diagnosed with allergic conjunctivitis and administered corticosteroid eye drops for 7 days.

Treatment with oral antiherpesvirus medication and hyaluronic acid eye drops was initiated. A genomic analysis of FHV-1 strains isolated on Day 0 and of specimens obtained on Day 3 for real-time PCR suggested that both cats were infected with the same strain as the F2 strain and that there was no mixed infection with the field strain. Real-time PCR was performed to identify ocular surface pathogens other than FHV-1, and feline calicivirus (FCV) was detected in specimens collected from the superficial corneal ulcers of both cats on Day 3.

Initial medical management included oral analgesics, oral anti-inflammatories, lifestyle changes, and epidural steroid injections. Ultimately, progression of the patient's clinical signs resulted in referral to a board-certified veterinary neurologist. Magnetic resonance imaging revealed marked bilateral L7 nerve root enlargement with L7-S1 foraminal widening and concurrent L7-S1 intervertebral disc extrusion, causing moderate to severe left-sided compression of the cauda equina. Given the marked changes of nerve roots on imaging and foraminal widening, consideration was given to a neoplastic process versus inflammatory neuritis.
