We present the case of a 52-year-old woman who presented to the emergency department with chest and neck pain. Initial cervical spine magnetic resonance imaging shows an abnormal flow void in the left vertebral artery, which prompted a computed tomographic angiogram. This demonstrated a hyperdense thickened ascending aortic wall, which extended into the great vessel origins. Clinically and radiographically interpreted as an acute aortic syndrome and/or intramural hematoma, the patient underwent ascending aortic repair with graft...

BACKGROUND: Pyoderma gangrenosum (PG) is an uncommon, ulcerative, cutaneous condition, often caused by surgical trauma that can masquerade as a pyogenic disease process requiring debridement and antibiotics. Treatment is, however, medical, with delay leading to significant morbidity. In addition, medical workup for coincident disorders has been suggested. The purpose of this study was to test the hypothesis that pediatric PG has differing disease associations and therefore requires a differing medical workup...

CONTEXT: Hyperinsulinemia can lead to pathologic ovarian growth and androgen production. CASE DESCRIPTION: A 29 year old woman developed an autoantibody to the insulin receptor (Type B insulin resistance), causing extreme insulin resistance and hyperinsulinemia. Testosterone levels were elevated to the adult male range. Treatment with gonadotropin releasing hormone (GnRH) analog led to normalization of testosterone, despite persistent extreme insulin resistance...

Metanephric adenofibroma is a rare, biphasic, benign tumor containing both stromal and epithelial components and could be potentially mistaken as Wilms' tumor (WT). We present a 5-year-old girl who was suspected to have metastatic Wilms' tumor on radiological investigations/tru-cut biopsy and had received neoadjuvant chemotherapy, but postoperatively final histopathology revealed it as metanephric adenofibroma. No postoperative chemotherapy was given.

This study aims to focus on a rare presentation of spinal hydatid cyst as cauda equine syndrome and misdiagnosed as intradural extramedullary (IDEM) benign lesion on magnetic resonance imaging. In this article, we report a case of spinal hydatid cyst masquerading as IDEM tumor, and intraoperatively, we accidently find clumped granuloma with severe arachnoiditis and hydatid cyst in lumber region, which was present as bilateral S1 radiculopathy with cauda equina syndrome. An 11-year-old boy who presented with symptoms and signs of cauda equina syndrome and planned for surgical excision...

Hydatid disease, caused by the larval stage of Echinococcus granulosus, is found most commonly in the liver and lungs, but no organ is immune. The ovarian involvement is often secondary to a cyst's dissemination localized in a different site. Occasionally, the cyst enlarges, thus mimicking an ovarian tumor. Patients with hydatid cysts at unusual locations present with atypical presentations and pose a diagnostic dilemma. A high index of suspicion is required in order to make a correct diagnosis pre-operatively to prevent spillage of the cyst contents during surgery...

Nasopharyngeal cancer (NPC) with mastoid recurrence is extraordinarily rare, and its development is thought to involve the Eustachian tube. We herein report a case of NPC with mastoid recurrence masquerading as acute otomastoiditis with facial paralysis in a 60-year-old man 44 months after concurrent chemoradiotherapy. The diagnosis was confirmed by exploratory tympanomastoidectomy with biopsy and Epstein-Barr-encoding region (EBER) in situ hybridization. Distant liver metastasis was detected simultaneously, and the patient underwent salvage treatment...

Urine drug testing is common for workplace drug testing, prescription management, emergency medicine and the criminal justice system. Unsurprisingly, with the significant consequences based upon the results of urine drug testing, a donor in need of concealing the contents of their sample is highly motivated to cheat the process. Procedures and safeguards ensuring sample validity are well known, and include measuring sample temperature at the time of collection, and laboratory measurements of creatinine, specific gravity and pH...

Primary neuroendocrine tumors of the upper urinary tract are extremely rare. We report a case of de novo small cell carcinoma of the ureter that presented masquerading as a distal ureteral stone. A 55-year-old lady presented to our clinic with 1 month history of right lower back pain and hematuria. Her history was notable for stage 1B mixed clear cell-endometroid cancer of the uterus status post radical abdominal hysterectomy with adjuvant radiotherapy, 7 years before the current episode. The patient had no evidence of recurrence...

BACKGROUND: Benign lichenoid keratosis (BLK, LPLK) is often misdiagnosed clinically as superficial basal-cell carcinoma (BCC), especially when occurring on the trunk. However, BCCs undergoing regression may be associated with a lichenoid interface dermatitis that may be misinterpreted as BLK in histopathologic sections. METHODS: In order to assess the frequency of remnants of BCC in lesions interpreted as BLK, we performed step sections on 100 lesions from the trunk of male patients that had been diagnosed as BLK...

Bulky naevocytoma of the perineum is a very rare variant of giant congenital melanocytic naevus (GCMN). It presents as a bulky naevocytic tumour in the perineal region with characteristic histological findings, such as extensive areas with a neural appearance called 'lames foliacees', formation of a pseudofollicular structure and extension of naevus cells between collagen bundles in a row called 'Indian-file' pattern. We report a case of late-onset bulky naevocytoma of the perineum in a 13-year-old girl. The patient presented with two bulky, pedunculated, heavily pigmented masses in the vulvar area that developed in a pre-existing GCMN lesion, which began around puberty and caused severe gait disturbance...

PURPOSE: We report a 75-year-old woman with a history of multiple myeloma immunoglobulin D (IgD) variant, who presented with an epibulbar plasmacytoma masquerading as a subconjunctival hemorrhage. METHODS: Magnetic resonance imaging of the brain and orbits with and without contrast was obtained and surgical biopsy of the subconjunctival lesion was performed; histopathology confirmed the diagnosis of plasmacytoma. RESULTS: Subconjunctival biopsy revealed a plasma cell neoplasm infiltrate in the episcleral layer...

The differential diagnoses for chronic peripheral neuropathy are broad and diagnosing a cause can be challenging. We present a case of isolated perineural spread of adenoid cystic carcinoma to the trigeminal nerve involving skull base foramina and Meckel's cave in the setting of chronic trigeminal neuropathy and no known prior malignancy. Computed tomography-guided core (CT) needle biopsy was needed to arrive at a diagnosis and a novel approach was required to obtain tissue from the trigeminal nerve lesion at foramen ovale...

The orthokeratinized odontogenic cyst (OOC) is a rare developmental odontogenic cyst that has been considered as a variant of the keratocystic odontogenic tumor until Wright (1981) defined it as a different entity. Recognition of OOC as a unique entity has long been due, yet its inexplicable clinical, radiographic presentation resembling dentigerous cyst due to its association to an impacted tooth, and its histological features makes it rather perplexing. This is the report of a case of OOC in relation to an impacted maxillary canine and its immunohistochemical analysis with Ki-67...

Neurocutaneous melanosis is congenital melanocytic nevus with neurological manifestations. We report a 4-year-old female child presenting with hyperpigmented and nodular skin lesion associated with developmental delay and convulsions. The child had multiple brownish-black nevi on the face and chest and giant melanocytic nevi on thoraco-abdomen, back, and gluteal region. Computed tomography scan of the brain showed calcification in the pons, right cerebellar hemisphere, and left medial temporal lobe. Skin biopsy done from nodular hyperpigmented site was suggestive of melanocytic nevi...

Nephron sparing surgery has seen a phenomenal rise in its application over the past few decades. The use of Surgicel and gel foam for closure of defect created after partial nephrectomy has become a routine practice at many centers. In this case report, we describe radiological artifact secondary to a surgical bolster mimicking a residual disease or an early recurrence in the kidney. This case highlights two facts; first, reapproximation of the renal tissue is best done without the use of Surgicel bolsters...

Genitourinary involvement of neurofibromatosis is uncommon and genital neurofibromatosis is even rarer. Involvement of clitoris by neurofibroma can lead to clitoromegaly masquerading as a male penis. We report such a case of ambiguous genitalia in a 7-year-old female child presenting with clitoromegaly since birth, in which magnetic resonance imaging (MRI) revealed the presence of extensive neurofibromatosis in the clitoris and lumbosacral regions. We emphasize the central role of MRI in evaluation of hormonal and non-hormonal causes of ambiguous genitalia...
