Periodic Drop Thumb, Hypokalemia and Adrenal Adenoma

چکیده
OBJECTIVE To report an unusual involvement of focal distal muscles but not proximal muscles in a patient with hypokalemic periodic paralysis (hypoPP). CLINICAL PRESENTATION AND INTERVENTION A middle-aged woman presented with episodic weakness of the bilateral thumbs lasting for 2 years. Hypokalemia and a left adrenal mass were subsequently found. Her weakness subsided after surgical removal of the adrenal mass, which was pathologically proven to be an adrenal adenoma. CONCLUSION The findings for this patient should alert physicians to consider focal distal motor paresis due to hypoPP. A preexisting occult trauma may predispose to paralysis at an atypical location in secondary hypoPP.

Primary hyperaldosteronism is one of the few causes of hypertension that can be cured by surgery. Primary hyperaldosteronism is caused by adrenocortical adenoma or hyperplasia. It is important to differentiate between adrenal adenoma and hyperplasia because the preferred treatments are different. In all patients with new-onest or worsening hypertension the primary hyperaldosteronism should be c...
متن کاملPrimary aldosteronism in a patient with an aldosterone-producing adenoma.
We describe an unusual patient presenting with a history of refractory hypertension and hypokalemia. Initial screening tests for adrenal hypertension were consistent with primary aldosteronism and an abdominal computed tomography scan showed an 8-mm left adrenal mass. However, adrenal venous sampling revealed markedly suppressed plasma aldosterone in the left adrenal vein but increased plasma a...

Thyrotoxic Periodic Paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. Thyroid-Stimulating Hormone (TSH)-secreting pituitary adenoma is a rare cause of hyperthyroidism. Even more rare is the occurrence of TPP as the first manifestation of a TSH-secreting pituitary adenoma. We report a 31-year-old Asian male patient suffering from TPP cau...

Primary aldosteronism is a potentially curable cause of hypertension, especially when caused by an adrenal adenoma. Aldosteronomas because of their small size often elude techniques to locate them. This case illustrates the advantages, disadvantages and complications of noninvasive techniques used for their diagnosis. A patient with hypertension and hypokalemia underwent an adrenal venous efflu...
متن کاملMalignant hypertension and hypertensive encephalopathy in primary aldosteronism caused by adrenal adenoma.
Two cases are reported as follows: 1) 1 female patient with accelerated-malignant hypertension secondary to an aldosterone-producing adrenal adenoma; and 2) 1 female patient with adrenal adenoma, severe hypertension, and hypertensive encephalopathy. This association is a rare clinical finding, and malignant hypertension may modify the hormonal characteristic of primary aldosteronism, making its...
