Objectives: To determine the spectrum of diseases that can involve the
rectus abdominis muscle and sheath (RMS) and to describe the clinical
features of these conditions. Method: A retrospective medical record
review of RMS disorders seen at The New York Hospital-Cornell Medical
Center from 1971 to 1992. Results: A total of 40 patients with disease
s of the RMS were identified. Thirty patients had primary diseases of
the RMS, most commonly desmoid tumor and hematoma. Secondary disorders
of the RMS included abscesses from diverticulitis, a perforated sigmo
id carcinoma, gallbladder empyema, and disseminated actinomycosis. Ele
ven of 18 patients with desmoid tumors had familial adenomatous polypo
sis (FAP). The desmoid tumors in patients with FAP resulted in greater
morbidity and mortality than those in patients without FAP. All patie
nts with hematomas were on anticoagulation or had a history of trauma,
vigorous coughing, or physical exertion. Conclusions: 1) RMS disease
should be suspected in patients with a palpable abdominal mass and a h
istory of familial adenomatous polyposis, trauma, anticoagulation, or
vigorous coughing or exercise, 2) The most common nonneoplastic condit
ion of the RMS is a hematoma, 3) The desmoid tumor is the most common
neoplasm of the RMS, 4) Abdominal ultrasonography and CT readily disti
nguish RMS disease from intraabdominal pathology.
