Ovarian adrenal rest tumor in congenital adrenal hyperplasia: Is medical treatment the first line option?

SUMMARY Ovarian adrenal rest tumors (OARTs) are very rare. We describe a case of a young woman with uncontrolled classical congenital adrenal hyperplasia (CCAH), presenting with bilateral OARTs, successfully treated with steroid replacement. A 20-year-old woman, known to have 21OH-CCAH, presented with severe abdominal pain, vomiting, diarrhea, and fever. As a result of poor compliance, 6 months before her admission hirsutism worsened and amenorrhea, hyperpigmentation, and weakness developed. ACTH levels were 278 < pmol/L and 17OHP 91.3 nmol/L. She was admitted for parenteral antibiotics and high-dose hydrocortisone treatment. CT revealed bilateral juxta-ovarian masses (6.2 x 3.6 x 7.4 cm left and 5 x 2.2 x 3.2 cm right) that on MRI were iso-intense in T1 and hypointense in T2, with early enhancement and rapid washout. One week of high-dose hydrocortisone resulted in significant clinical and laboratory improvement and the patient was discharged with 2 mg dexamethasone/day. One month later US revealed shrinkage of the masses and dexamethasone dose was decreased. At three months from discharge, she has resumed regular menses, and a repeated MRI revealed the para-ovarian masses have shrunk. One year after the diagnosis, the para-ovarian masses have shrunk more to 2.8 x 1.9 x 4.3 on the left and 2.1 x 0.9 x 1.2 on the right with less contrast enhancement in comparison to previous test possibly due to fibrotic changes of the tissue. OARTs are rare tumors with a poorly known natural history, and surgery has been the first option in the few reported cases. We demonstrate that medical treatment is a good alternative, leading to significant tumor shrinkage over a short period.

Humoral hypercalcemia of pregnancy treated with bisphosphonates

SUMMARY Hypercalcemia can be hazardous during pregnancy, most cases being due to primary hyperparathyroidism. We report a case of hypercalcemia with suppressed PTH levels necessitating treatment with bisphosphonates during pregnancy. A 38-year-old woman at the 26th week gestation was admitted because of symptomatic hypercalcemia. She did not take any medication that could influence her calcium levels. Physical examination was unremarkable. Laboratory tests on admission were: calcium 12.7 mg/dL (8.5-10.5 mg/dL), phosphorus 1.8 mg/dL (2.5-4.5 mg/dL) and PTH on 3 consecutive tests 1.2, 1.3 and 1.2 pg/mL (15-65 pg/mL). Her 24h urine calcium was 900 mg, 25-OH-D 40 ng/mL (30-58 ng/mL) and 1,25-OH-D 99 pg/mL (80-146 for women in the third trimester). Abdominal ultrasound revealed multiple hypervascular liver lesions consistent with hemangiomas by MRI. Breast and neck ultrasound were normal, and chest CT revealed few non-significant 0.3-0.7 cm pulmonary nodules with no change after an interval of 3 months. She was treated with isotonic saline, loop diuretics and calcitonin. Despite this treatment, calcium levels remained high (14.1 mg/dL), and pamidronate was initiated. On 35th week gestation, she underwent a cesarean section complicated by hypocalcemia of the newborn. Eight weeks after delivery, her calcium levels are 9.4 mg/dL and PTH 18 mg/dL. According to the extensive workup and the post-partum normalization of PTH and calcium levels, we conclude that excessive secretion of placental PTHrP was the cause of hypercalcemia in this patient. No significant adverse effect of bisphosphonate on the mother or baby were seen at the short term follow up.
