A 13-year-old girl presented to our emergency with a one week history of fever and skin rash and new onset of chorea for the last three days. There was a long standing history of right predominant headache; followed by personality change, fatigue, arthralgia and weight loss over the last few months. Previous investigations by head CT and ophthalmological examination did not explain the symptoms. Further investigations revealed peri- and pancarditis with aortic insufficiency, a renal involvement with elevated creatinin, protein- and hematuria and a hemolytic anemia. Diagnosis of lupus eythematodes was confirmed by high ANA, anti-dsDNS and Anticardiolipin antibodies. Within the first 48 hours after admission there was significant deterioration with reduced vigilance and dysarthria. MRI of the brain and dopplersonography of cerebral vessels showed a complete thrombosis of the right medial cerebral artery with a small net of collaterals, irregularities of the left cerebral artery due to vasculitis and several subacute leftsided ischemias. Immunosuppressive therapy with high-dose corticosteroids and cyclophosphamid together with antithrombotic therapy induced an improvement of neurologic, renal and cardiac function.

A 69-year-old male (case 1) was admitted due to acute non-ST-segment elevation myocardial infarction (NSTEMI). Eight years earlier, he had previously undergone treatment with a sirolimus-eluting stent (SES). Four years after stent implantation, a follow-up angiography was obtained showing a patent stent without obstructive in-stent restenosis (Panel A). Angiograms obtained at the time of NSTEMI (Panel B) disclosed subtotal occlusion in the middle of the SES (arrowheads). Optical coherence tomography revealed a signal intense luminal layer with an underlying, highly attenuating, diffusely demarcated area, suggestive for an instent fibroatheroma (Panel D) with a minimal cap thickness of 80 µm. Accordingly, ischaemia was caused by the high degree of stenosis (Panel E). Similarly, a 59-year-old male (case 2) was admitted due to STEMI. Nine years before, he had received a paclitaxel-eluting stent (PES). Five years after stent implantation, a follow-up angiography revealed a patent stent (Panel F). Angiograms obtained at the time of STEMI (Panel G) disclosed total occlusion in the proximal of PES (arrowheads). Optical coherence tomography showed a rupture of thin cap fibroatheroma within the stented segment (Panel I). The thin cap fibroatheroma caused a severe stenosis with superimposed thrombus (Panel J). Neoatherosclerosis has been recently described as particular disease entity being responsible for very late stent failures. These two cases illustrate that the presence of a favourable long-term angiographic result years after DES implantation does not exclude a future neoatherosclerosis-related event (restenosis or stent thrombosis). Large observational and long-term intracoronary imaging studies are required to fully elucidate the dynamics and clinical relevance of neoatherosclerosis.

Cytomegalovirus infections are widely distributed with a seroprevalence of up to 100%. The majority of the cases take a silent course or deal with unspecific clinical symptoms. Complications in immunocompetent patients are rare but may affect the liver and lead up to an acute organ failure. In this case report, we describe a 35-year-old immunocompetent female with an acute cytomegalovirus infection presenting as acute hepatitis with ongoing upper right abdominal pain after cholecystectomy. Upper right abdominal pain is a common symptom with a wide range of differential diagnoses. If common reasons can be excluded, we want to sensitize for cytomegalovirus infection as a minor differential diagnosis even in immunocompetent patients.
