Intrathyroid parathyroid adenoma - Report of two cases

Abstract

Intra thyroid parathyroid adenoma is a
rare presentation. It may be frequently
misdiagnosed in initial stage of the disease.
Its location is usually achieved by
cervical ultrasound and scintigraphy.
Similarity in cytological picture between
thyroids and parathyroids may further
complicate diagnosis by fine needle aspiration
cytology. Nuclear imaging scintigraphy
accurately localizes the tumor in
90 of cases.We had two cases of intra
thyroid parathyroid adenoma which confirmed
by nuclear imaging scintigraphy
and managed surgically.
Keyword :None. INTRODUCTION Primary
Hyperparathyroidism is known to
present with protean manifestations leading
to misdiagnosis in the initial stages of
the disease due to inability to locate the
adenoma in an ectopic parathyroid
gland1. Aberrant migration during development
may lead to intrathyroidal or
other ectopic locations of parathyroid
glands2.
This may lead to their misdiagnosis as a
thyroid nodule or failure to locate parathyroids
during surgery. We herein report two
cases of intrathyroidal parathyroid adenoma.
In the first case, preoperative localization
studies confirm the intrathyroidal
adenoma. In the second case, intrathyroid
parathyroid adenoma was diagnosed postoperatively
after histopathological examination
of the specimen.
