A patient with systemic lupus erythematosus developed an acute surgical abdomen secondary to spontaneous rupture of the liver and died. Postmortem examination revealed an arteritis of the liver, pancreas, adrenal gland, skeletal muscle, and spleen. It appeared that an arteritis of the liver produced areas of infarction that ruptured and caused the clinical findings.The clinical features of patients with systemic lupus erythematosus (SLE) vary depending on the organs involved. One organ, the liver, is rarely involved with clinically significant disease ( I ) . We report an unusual case of SLE with spontaneous rupture of the liver secondary to arteritis.
CASE REPORTA 27-year-old black female with SLE was admitted to the University of Virginia Medical Center for evaluation of Submitted for publication May 7. 1976; accepted September 27. 1976. renal failure. SLE was diagnosed in 1967 because of Raynaud's phenomenon, arthritis, malar facial rash, sun sensitivity, and positive lupus erythematosus cell test and serum fluorescent antinuclear antibody test. She responded to prednisone. which was discontinued in 1970. Later she took aspirin for intermittent arthritis. She remained relatively well until the twenty-fourth week of her fourth pregnancy, when proteinuria was first detected. At that time a creatinine clearance was normal. but serum concentration of C3 was low. One month before admission, following the delivery of a 32-week old baby. she developed intermittent abdominal pain, hypertension, ascites. and a n elevated serum creatinine (3.5 mg/dl).On physical examination the patient was in no acute distress. Vital signs were normal except for a blood pressure of 160/100 rnm Hg. There was mild erythema and hypopigmentation over the bridge of the nose and rnalar area. A grade 2/6 systolic ejection murmur was heard along the left sternal border without radiation. The abdomen was nontender, tense with fluid, and without organomegaly. Pelvic and rectal examinations were unremarkable. Edema of the legs and sacrum were noted, as were small effusions of both knees.Admission laboratory data included a blood urea nitrogen of 58 mg/dl, serum creatinine 2.9 mg/dl, serum albumin 2.5 mg/dl, urinalysis 3+ protein with 9 white cells per high power field, a 24-hour total urine protein of 2.8 g. hematocrit 34% and white blood count 9400/mm3, positive fluorescent antinuclear antibody test, and total hernolytic complement 21 units (normal: 3 4 4 8 units). Cryoglobulins, anti-DNA antibody, and Clq precipitable immune complexes were not detected. Roentgenograms of the abdomen showed diffuse haziness consistent with intraperitoneal fluid. A chest roentgenogram demonstrated elevated diaphragms bilaterally with right basilar atelectasis. A diagnostic paracentesis yielded clear yellow fluid with 48 white blood cells/mm3 (56% polymorphonuclear leukocytes and 44% monocytes), glucose of 103 mg/dl, and protein of 3.0 g/dl. N o organisms were cultured from the fluid and malignant cells were not revealed by cytologic examination.
