Bilateral Adrenal Incidentalomas: A Case Report and Review of Diagnostic Challenges When incidentally discovered adrenal masses are bilateral, a refined diagnostic approach is warranted since bilateral disease is more likely to be pathologic. We review a case of a 34-year-old man with incidentally discovered bilateral adrenal nodules.n the case of the bilateral adrenal incidentaloma, patients who present with symptoms such as hypotension, dizziness, weight loss, or abdominal pain in the setting of bilateral adrenal masses should be evaluated for adrenal insufficiency using an ACTH stimulation test (Table 1).

- This is why transbronchial biopsy has such a high diagnostic yield and is the favored means of obtaining tissue for diagnosis. The involvement of the lung parenchyma by sarcoidosis can have very different appearances ranging from reticulonodular lung tissue densities to multiple masses and miliary lesions. These radiographic expressions of sarcoidosis can mimic many other diseases including malignancies and infections which involve the lungs.

- In children, hypoparathyroidism most often results from destruction of the thyroid gland as a result of an autoimmune disorder. This may be associated with type 1 diabetes mellitus and thyroid disorders. Hypoparathyroidism may occur when the parathyroid tissue is destroyed by amyloidosis (the buildup of a waxy substance in tissues and organs), hemochromatosis (excess iron storage), or malignant (cancerous) tumors.

Endometrial stromal sarcoma Undifferentiated uterine sarcoma, or undifferentiated (high-grade) endometrial stromal sarcoma, does not resemble normal endometrial stroma and behaves much more aggressively, frequently metastasizing.The differential includes leukemia, lymphoma, high-grade carcinoma, carcinosarcoma, and differentiated pure sarcomas.here are three grades for endometrial stromal tumors, as follows. It was previously known as endolymphatic stromal myosis because of diffuse infiltration of myometrial tissue or the invasion of lymphatic channels.

- True thyrnic hyperplaisa is characterized by massive thymic hypertrophy however, the normal thymic architecture is retained3. Massive thyrnic hyperplasia (MTH), a rare variant of hyperplasia of the thymus, is known to cause mediastinal compression or acute and recurrent respiratory infections in the pediatric age group. It needs to be distinguished from other commonly seen masses of the anterior mediastinum2.

Thymus disorders Any condition affecting the thymus. The thymus is the infection fighting immune system gland which is larger in children than adults. It is located in the top part of the chest.

Symptoms of acromegaly include abnormal enlargement in bones of the hands, arms, feet, legs, and head.n rare cases, non-pituitary tumors in the pancreas, lungs or adrenal glands may cause acromegaly. These tumors may directly produce excess growth hormone or they may produce growth hormone-releasing hormone (GHRH), which stimulates the pituitary gland to release GH.

- Goldenhar syndrome has a wide range of. manifestations including craniofacial, vertebral, cardiac, renal and central nervous system. anomalies. The classic facial aspect of. Goldenhar syndrome is described as hemi. facial microsomia. The typical presentation of. Goldenhar syndrome includes epibulbar. dermoids, microtia, mandibular hypoplasia, strabismus, most probably caused by develop-. mental defects of first & second branchial. arches and vertebral anomalies [3].

Definitions &Translations Thymoma is an uncommon tumor, best known for its association with the neuromuscular disorder myasthenia gravis; thymoma is found in 20% of patients with myasthenia gravis. Once diagnosed, thymomas may be removed surgically. In the rare case of a malignant tumor, chemotherapy may be used.

Original contributionPleuroparenchymal fibroelastosis: a pattern of chronic lung injury â ââ Histologic examination of H&E-stained slides showed a heterogeneous pattern of normal-appearing lung parenchyma next to patches of severe diffuse interstitial fibrosis composed primarily of elastic fibers, consistent with PPFE (Fig. 5 A-D).

Cortical Lesions of the Tibia: Characteristic Appearances at Conventional Radiography The tibia and fibula are the most common locations. The epicenter is cortical. The appearance consists of diffuse, mature cortical thickening. Severe venous insufficiency or venous ectasia can result in tibial or fibular cortical thickening secondary to mature periosteal bone formation (Fig 27).Venous stasis is probably the most common cause of diffuse cortical thickening in the tibia.tress fracture occurs at all ages, and there is no sex predilection. The location is diaphyseal in the tibia, and the epicenter is eccentric. The appearance consists of smooth cortical thickening, sometimes associated with lucent foci.

- LYMPHADENOPATHY ON CT. Bilateral symmetric hilar and right paratracheal mediastinal adenopathy, as in this patient, is the most common pattern of lymphadenopathy in sarcoidosis. Computed tomography shows para-aortic and retrocaval lymphadenopathy. CT can demostrate enlarged lymph nodes which are not visible on radiographs. There is an enlarged ...ilar lymphadenopathy has not been found to develop or increase after a patient has presented with Stage III sarcoidosis. If a patient with only parenchymal lung disease on a chest radiograph developes or has an increase in lymphadenopathy, the patient either has an incorrect diagnosis or a second disease.

Imaging in Adrenal Metastases A metastatic melanoma to the right adrenal gland appears as a hyperintense mass on this T1-weighted MRI. Chemical-shift imaging with in-phase and out-of-phase imaging techniques is used to exclude metastatic disease by detecting the presence of intracellular lipid within adrenal gland lesions.

- No edema or cortical irregularity is present. Anteroposterior radiograph of the distal tibia shows a solitary, small, well-defined lucent lesion in the lateral distal tibial metadiaphysis that abuts the cortex. This finding is consistent with a benign fibrous cortical defect or nonossifying fibroma.Note the lack of multiple lobulations in this early lesion.nteroposterior radiograph of the distal tibia shows a solitary, small, well-defined lucent lesion in the lateral distal tibial metadiaphysis that abuts the cortex.
