The female patient initially showed the acquired type of total lipoatrophy at about 8 years of age. At 12 years of age, the onset of diabetes mellitus was speculated from advanced pyodermia and dedentition. At 29 years of age, glucosuria was found, and she developed proteinuria, ascites, and pretibial edema. The physical examination revealed: hepatosplenomegaly, complete absence of subcutanous fat, cutaneous xanthomas, and emaciated facies with pronounced zygomatic arches. Diabetic retinopathy was revealed in the ophthalmological examination, and nephropathy was evident in renal biopsy specimens. She also had peripheral diabetic neuropathy. No adipose tissue was found in the mesenterium under peritoneoscopy. The hepatic biopsy specimen revealed advanced portal liver cirrhosis. Laboratory findings included: hyperlipidemia, elevation of BMR without evidence of hyperthyroidism, impaired renal function, and undetected anti-insulin antibodies and anti-insulin antibodies. Endocrinological examinations revealed normal value, except for an impaired hGH response in the arginine test. C-peptide immunoreactivity was high. Her condition was fairly well controlled by 140 units of insulin injection daily.

Frequency-selective chemical shift magnetic resonance (MR) imaging was applied on the calf musculature and the abdomen of a patient with acquired generalized lipoatrophy (AGL; Lawrence syndrome), a very rare syndrome affecting selectively several types of adipose tissue accompanied by alterations in glucose and energy metabolism. In addition, (1)H-MRS was used for assessment of intra- (IMCL) and extramyocellular lipid stores (EMCL) in the skeletal musculature of the calf. Results from the AGL patient were compared with an age-matched group of five healthy volunteers. Fat-selective imaging of the calf revealed a total lack of subcutaneous adipose tissue. No EMCL signal was found in the spectra from the soleus muscle of the AGL patient. IMCL signals were present in the spectra but were clearly lower than in the controls (14% of normal value in the soleus muscle). In abdominal images, subcutaneous fat signal was not detectable, as in the calf, but nearly normal conditions were shown for visceral adipose tissue between abdominal organs. Fat-selective images showed the liver with high signal intensity, indicating hepatic steatosis combined with hepatosplenomegaly. Modern chemical shift-selective MR imaging and localized spectroscopy allow a noninvasive and quantitative assessment of tissue composition in patients with disorders of carbohydrate and lipid metabolism.
