Hypoechoic Mass (hypoechoic + mass)
Selected AbstractsPrenatal diagnosis of an intertwin membrane hematomaJOURNAL OF CLINICAL ULTRASOUND, Issue 7 2010Marian Kacerovsky MD Abstract We report a case of a 26-year-old woman, gravida 2, para 1, with a dichorionic diamniotic twin pregnancy at 33 weeks of gestation with a 1-day history of mild vaginal bleeding and irregular uterine activity. Ultrasonography showed 18 × 15 × 3-cm-sized complex hypoechoic mass located in the dividing intertwin membrane. Based on this finding, the diagnosis of an intertwin membrane hematoma was made. This unusual sonographic diagnosis was confirmed during the cesarean section. In the case of dichorionic twin pregnancy, partial placental abruption can lead to a subclinical intertwin membrane hematoma. © 2010 Wiley Periodicals, Inc.

Most common sites are head, neck and axilla, and scrotal lymphangioma is very rare. Lymphangiomas are classified as capillary, cavernous, and cystic type and cystic type is most common. Complete surgical excision is definitive treatment and incomplete excision leads to local recurrence. We report a case of scrotal lymphangioma in 68-year-old male patient. Gray-scale sonography revealed multiseptated, hypoechoic mass abutting the upper pole of the normal right testis. Color Doppler sonography showed no remarkable blood flow in the mass. MRI demonstrated multispetated extratesticular and extraepididymal mass in the right scrotum. Surgical excision was performed and the histopathologic diagnosis was a cystic lymphangioma. In conclusion when multiseptated cystic scrotal mass was discovered in an elderly patient, scrotal lymphangioma should be included in differential diagnosis. © 2009 Wiley Periodicals, Inc. J Clin Ultrasound 2009 [source] A rare case of granulomatous prostatitis caused by Mycobacterium tuberculosisJOURNAL OF CLINICAL ULTRASOUND, Issue 1 2007Sadık Tamsel MD Abstract We report a rare case of infective granulomatous prostatitis caused by Mycobacterium tuberculosis that may be mistaken for prostatic carcinoma, both on clinical examination and transrectal sonography (TRUS). A large hypoechoic mass was detected in the prostate of a 46-year-old man during TRUS and histopathologic examination after TRUS-guided biopsies reported the diagnosis of tuberculous prostatitis. We herein describe the clinical and TRUS findings of this case. © 2006 Wiley Periodicals, Inc. J Clin Ultrasound, 2006 [source] Role of sonography in diagnosing and staging invasive lobular carcinomaJOURNAL OF CLINICAL ULTRASOUND, Issue 7 2004Veronica L. Selinko MD Abstract Purpose The goal of this study was to compare the sensitivity of sonography with that of mammography in the detection of invasive lobular carcinoma (ILC), to identify ILC's typical imaging characteristics, and to further show the important role of ultrasound in the staging and treatment planning of this elusive tumor. Methods We identified all patients with ILC seen at our institution from 1998 through 2001; 62 had pathologically proven pure ILC. We retrospectively reviewed and analyzed the sonographic appearances in correlation with mammographic, pathologic, and clinical findings. We reviewed the results of sonographic examinations of the nodal basins and fine-needle aspiration (FNA) of suspicious nodes and correlated them with initial clinical and final pathologic staging. We noted all cases of multicentricity or multifocality and analyzed the relative sensitivity of mammography and sonography according to tumor size. Results Sonography had a sensitivity of 98% versus 65% for mammography. The most common mammographic pattern was a spiculated mass or architectural distortion (39%). On sonography the most common pattern was a hypoechoic mass with (58%) or without (27%) shadowing. An infiltrative pattern was observed in 13% of the cases. Ultrasound-guided FNA confirmed disease was present in the axillary lymph nodes in 21% of the patients, and sonographic examination of the nodal basins resulted in a change of clinical staging from N0 to N1 in 75% and from N1 to N0 in 30% of the cases. Multicentricity/multifocality was identified sonographically and proved by FNA in 21% of patients. Conclusions Sonography has a much higher sensitivity than mammography in detecting ILC and therefore is an important adjunctive tool in the diagnosis of this form of cancer. Routine examination of node-bearing areas in patients with ILC proved useful in refining the disease staging. © 2004 Wiley Periodicals, Inc.

Methods We retrospectively reviewed the sonograms and pathology specimens of 24 patients with pathologically proven epidermal inclusion cysts. We evaluated the lesions for shape, size, internal echogenicity, posterior sound enhancement, and presence of color Doppler signals. We classified the masses into 5 sonographic types according to their internal echogenicity. The relationship between the sonographic types and the pathologic findings was examined. Results The masses were ovoid or spherical in 17 cases (71%), lobulated in 5 (21%), and tubular in 2 (8%). The longest diameter ranged from 1 to 6 cm (mean, 3.1 cm). Twenty-three cases (96%) were associated with posterior sound enhancement. Color Doppler signals were absent in 20 cases, but some vascularity was noted in 4 ruptured epidermal cysts, in areas of granulation tissue. The most common sonographic type was a hypoechoic lesion with scattered echogenic reflectors (10 cases). Sonographic findings were related to the lamellation of keratin debris and the granulation tissue secondary to rupture. Most cases with a lobulated configuration (4 of 5) or color Doppler signals (4 of 4) were ruptured cysts. Conclusions Epidermal inclusion cysts most often appeared sonographically as a hypoechoic mass containing variable echogenic foci without color Doppler signals. Ruptured epidermal cysts, however, may have lobulated contours and show color Doppler signals, mimicking a solid mass. © 2001 John Wiley & Sons, Inc.

Ding Abstract The purpose of this article was to describe the clinical and microscopic features of a foreign-body granuloma in submental region that resulted from a fish bone embedded in the floor of mouth. A 45-year-old female patient complained of a hard mass in submental region. Clinical examination showed a non-compressible, firm, fixed lump, painless on palpation. Ultrasound examination showed an internally uneven, uncircumscribed, hypoechoic mass with a steaky hyperechoic spot of 1.1 cm length in the center. A microscopic examination showed newly-formed granuloma, composed of lympocytes and epithelioid cells, and some microabscess with neurophiles. The final diagnosis was a foreign-body granuloma with fish bone. Even though foreign-body granulomas in submental region are rare lesions, surgeon should be familiar with their features and include them in the differential diagnosis of tissue masses. [source] Tamoxifen in the Management of Pseudoangiomatous Stromal HyperplasiaTHE BREAST JOURNAL, Issue 6 2001Sandhya Pruthi MD Pseudoangiomatous stromal hyperplasia (PASH) is a relatively uncommon histologic finding in breast specimens. The clinicopathologic spectrum of this disease entity can range from a focal nonsignificant microscopic finding to a dominant palpable breast mass. To confirm the diagnosis, a biopsy is required primarily to distinguish PASH from a low-grade angiosarcoma. The mammographic description of PASH is a round or ovoid, circumscribed or partially circumscribed mass. The sonographic feature is a hypoechoic mass. PASH is similar to a fibroadenoma in clinical and imaging features. Progressive breast enlargement associated with engorgement, cyclical breast pain, and burning sensation is of significant concern for some women. The management of the palpable mass and associated symptoms has included excisional biopsy, often leading to recurrent excisions and even mastectomy. This report documents an impressive response to tamoxifen in a patient with PASH presenting with breast enlargement, pain, and breast masses. To our knowledge, there are no reports on the use of tamoxifen or other selective estrogen receptor modulators in the management of this benign breast condition. [source] Diabetic Fibrous Mastopathy: Case Reports and Radiologic-Pathologic CorrelationTHE BREAST JOURNAL, Issue 6 2000Julie K. Shaffrey MD Abstract: Diabetic fibrous mastopathy, an unusual finding in patients with early onset, long-standing insulin dependent diabetes, can present as a palpable mass with mammographic and sonographic findings highly suggestive of breast cancer. These suspicious clinical and imaging findings necessitate a biopsy, which demonstrates characteristic findings of dense, keloid scarring and intralobular lymphocytic infiltrates. We present 2 cases of diabetic fibrous mastopathy with characteristic mammographic, sonographic, and pathologic findings diagnosed with ultrasound guided core needle biopsy and confirmed with surgical excision. In the appropriate clinical setting, a patient with long-standing insulin dependent diabetes with a firm, mobile breast mass and characteristic sonographic findings of a hypoechoic mass with lobulation and marked posterior acoustic shadowing should suggest the possibility of diabetic fibrous mastopathy. Awareness of this entity may obviate the need for surgical excision in patients whose clinical, imaging, and pathologic findings are consistent with diabetic fibrous mastopathy.

Hassan Summary Genitourinary tuberculosis (TB) is the most frequent manifestation of extrapulmonary TB, where the epididymides, seminal vesicles and prostate are the commonly infected sites, followed by the testes. We report a 29-year-old man who presented with primary infertility since 2 years. He had a history of bilateral painful scrotal swelling with fever since 4 years, diagnosed as pyogenic scrotal abscess, which was managed by incision and drainage. At presentation, fever, weight loss and night sweats were absent. On examination, he had ovoid slightly tender, firm to hard irregular masses in the lower poles of both testes with no line of separation encroaching on both epididymes. Both testes were not felt distinctly and the overlying scrotal skin showed no signs of inflammation. Semen analysis revealed azoospermia. Scrotal colour coded duplex ultrasonography demonstrated moderately enlarged testes having well defined hypoechoic masses with foci of calcifications. Magnetic resonance imaging confirmed these findings. Biopsy and histopathology detected the presence of caseating granuloma and Ziehl,Neelsen staining of paraffin sections demonstrated acid-fast bacilli. The patient was treated with combination therapy. Tracing of the condition is discussed. [source] | ||||||||||
