Congenital anomalies of the MCA are rare compared with the rest of the intracranial vasculature. An aplastic MCA, known as a twiglike MCA, is the result of replacement of MCA trunk by a plexiform network of small vessels. In this report, we aim to review the radiologic features of a twiglike MCA and its differential diagnosis, helping the reader differentiate this entity from more common pathologies to avoid unnecessary further investigation.

Abstract Objective: Placental mesenchymal dysplasia (PMD) is a rare vascular anomaly characterized by mesenchymal stem villous hyperplasia. Accurate differential diagnosis of PMD is crucial to predict fetal outcomes associated with serious obstetrical complications. Methods: We reviewed the clinical and pathological features and immunohistochemical and imaging findings of three patients with PMD. Results: First trimester sonographic cystic findings identified molar pregnancy or PMD. However, PMD was highly suspected according to the maternal serum human chorionic gonadotropin (hCG) titers, fetal karyotypes, and imaging findings. The outcome of patient 1, in whom placental multicystic areas decreased as pregnancy progressed, was a live birth. In contrast, the babies of patients 2 and 3 were stillborn, and multicystic formations detected during the first trimester completely and consistently occupied the placentas. Pathological and immunohistochemical analyses using anti-CD34 and anti-D2-40 antibodies distinguished the cisternae from multiple small vessels in the villi. Immunohistochemical analyses using anti-CK7 and anti-Ki-67 antibodies did not detect excessive proliferation of trophoblasts. Most abnormal villi associated with PMD comprised stromal cells that did not react with an anti-p57kip2 antibody. Conclusion: In patients with PMD, if the percentage of the normal placental area decreases as pregnancy progresses, the possibility of fetal growth restriction and intrauterine fetal demise should always be considered. The immunostaining pattern of CD34 and D2-40 may represent a unique feature of PMD and can provide supporting evidence for the differential diagnosis of PMD.

Choledochal cysts are rare congenital anomalies that have a variable presentation with occasional diagnostic and therapeutic dilemmas. Our case is a 14-year female presented with recurrent abdomen pain with confusing diagnostic findings, suggestive of a large choledochal cyst (22x29x17cm) initially managed by percutaneous tube biliary drainage and later underwent excision and HPE revealing non-malignant findings. The choledochal cyst should always be a differential diagnosis for any patient presenting with an abdominal mass and should be managed accordingly.

With the use of sophisticated imaging modalities, congenital anomalies of the inferior vena cava and its tributaries, such as agenesis of the hepatic vena cava, are becoming more and more commonly encountered. Scimitar syndrome, also called venolobar syndrome and hypogenetic lung syndrome, is a rare pulmonary vascular anomaly of the right lung that can sometimes be associated with some cardiovascular anomalies. We present here a case with agenesis of the hepatic vena cava associated with scimitar syndrome.

Abstract Purpose The main objective of this study is to demonstrate the diagnostic accuracy of susceptibility-weighted angiography (SWAN) in the diagnosis of slow-flow cerebral vascular malformations, especially developmental venous anomaly (DVA). We also aimed to determine the prevalence of DVAs identified by SWAN at 1.5 T. Methods We retrospectively evaluated 1,760 axial SWAN images for the diagnosis of low-flow vascular anomaly. Among them were 305 patients who underwent contrast-enhanced examination due to different indications. Postcontrast images were analyzed by different radiologists who were blinded to patients. The presence of DVA and other features such as location, length, depth, and direction of drainage vein was evaluated. Results Twenty-six patients with DVA had both SWAN and postcontrast images. There were four false-negative patients with SWAN. The sensitivity of the SWAN sequence was 84.6%. In addition, totally 77 DVA (4.36%), 2 capillary telangiectasia (0.11%), and 2 cavernous malformations (0.11%) were detected in 1,760 patients. Conclusion SWAN is an effective method for the diagnosis of developmental venous anomalies and other low-flow cerebral vascular malformations. Especially in the pediatric age, susceptibility-weighted imaging sequences are useful to limit contrast use.

Background: Clinically, the recurrent artery of Heubner (RAH) aneurysm is extremely rare, commonly presents with subarachnoid hemorrhage (SAH). Case Report: A 73-year-old man with a known moyamoya disease who presented as caudate hemorrhage attributable to an incidental flow aneurysm distal on the right RAH, which was managed conservatively after an unsuccessful endovascular attempt. Unfortunately, the patient died five weeks after  hospital discharge because of re-rupture of the aneurysm. To the best of our knowledge, the RAH aneurysm manifesting as caudate hemorrhage without SAH has not previously been reported. Conclusion: This case highlights that the RAH aneurysm masquerading as caudate hemorrhage without SAH is exceedingly rare but can be encountered, representing a diagnostic and therapeutic challenge, and should be considered in the differential diagnosis. Moreover, early identifying and then eliminating such vascular anomaly if possible is of importance to prevent fatal hemorrhage.

Pigmented villonodular synovitis, a rare proliferative disease of unknown etiology, is rare in the foot (2% of these lesions). A retrospective review was undertaken of the case histories, radiographs, and imaging results of eight patients treated for pigmented villonodular synovitis of the foot. Pigmented villonodular synovitis was located in the rearfoot in five patients and in the forefoot in the other three. Radiographs in six patients showed bone involvement. Affected bones included the talus, first cuneiform, first and fifth metatarsals, and second phalanx. Treatment was surgical, and only one recurrence was recorded after 24 months. Pigmented villonodular synovitis should be considered in the differential diagnosis of foot tumors. (J Am Podiatr Med Assoc 97(5): 415–419, 2007)

AbstractFibro adipose vascular anomaly (FAVA) is a rare type of vascular malformation with distinct clinical features. The authors here discussed the clinical, imaging, differential diagnosis, histopathological features, and treatment options of FAVA along with an illustrative case. It is important to know about this uncommon entity as this can be misdiagnosed due to the overlapping clinical features with other common entities. It is a benign condition with no proven malignant potential. There are no guidelines regarding the best treatment option.

A case of chondrodystrophia calcificans congenita in a newborn infant, born of a hypothyroid mother who had episodes of tetany during pregnancy, is reported. On the basis of a review of significant findings in 88 cases reported in the world literature the following conclusions are drawn. Chondrodystrophia calcificans congenita is a disorder that is well established at the time of birth. The diagnosis is based primarily on roentgenologic findings; it may be missed either if insufficient indication for radiologic investigation is present or if radiologic investigation is delayed beyond 4 years of age, when the epiphyses begin to fuse. A possible relationship between this disorder and dysplasia epiphysialis multiplex is indicated by the similarity in the radiologic features of each and the inability to differentiate between the two, once epiphysial fusion has commenced. One wonders whether the reported cases of dysplasia epiphysialis multiplex may represent partial fusion in chondrodystrophia calcificans congenita. Further pathologic investigation is necessary to elucidate this point. Maternal hypothyroidism may have a teratogenic role in this disorder, as in other congenital anomalies. In those patients surviving infancy and childhood, the prognosis for useful function is good if anomalies of other systems are not present. The skeletal deformities can be managed by orthopedic surgery, and the cataracts can be extirpated.
